16 Best MP4 to MP3 Converters [Software & Apps]

I'll be honest, I never gave much thought to MP4-to-MP3 conversion tools until I recently needed one. I had recorded a podcast interview as a video file, and all I wanted was to extract the audio, edit it, and upload it. Of course, my reason wasn’t far-fetched; the video was eating up storage space on my phone, and I just needed a clean, lightweight MP3 I could work with. That's exactly what led me to test different converters.

While exploring, what shocked me wasn’t how many options exist, but how wildly different they perform. Some desktop apps converted my 2GB video file in under three minutes. Others took forever, and some even crashed halfway through. Generally, most online tools seemed convenient at first, until the watermarks, file limitations, and upload caps almost had me frustrated. Similarly, mobile apps worked fine for short clips, but in most cases, they struggled with anything longer than 10 minutes.

After weeks of testing, crashes, and more than a few headaches, I found the converters that actually delivered results. I tested desktop software like Movavi Video Converter and HandBrake, tried online tools like Convertio and FreeConvert, and put mobile apps through their paces on both Android and iOS. Some impressed me with their speed and reliability. Others let me down with hidden limitations and poor quality output.

That being said, whether you're extracting audio from videos for podcasts, creating music libraries, or just trying to save storage space, these are the 16 MP4 to MP3 converters that I found to deliver consistently.

There are quite a few desktop converters that you can download. Some are designed for Windows 8, 10, 11, and others are for Mac and other operating systems. With a download, you never have to worry about being connected to the internet.

Why I picked it: from my observation, speed defines Movavi. I couldn’t overlook the fact that it converted a 2-hour video file in under 10 minutes while maintaining pristine audio quality.
OS: Windows, macOS

Movavi Video Converter handles MP4 to MP3 conversion with impressive efficiency. I tested it with files ranging from short clips to full-length recordings, and it consistently delivered fast, high-quality results. The interface feels intuitive: you drag in your MP4 file, select MP3 as the output format, and conversion begins immediately without any complication. Even better, I like that it doesn't bog down your system during conversion, and I could use it over a long stretch lag-free.

Another intriguing thing about Movavi Video Converter is that it supports over 180 formats and includes preset profiles for various devices, thus simplifying conversion for specific hardware. While testing, I also appreciated the basic editing tools that let me trim unwanted sections before conversion, saving me from having to open a separate editor.

Meanwhile, the recently introduced AI upscaling feature also works well for enhancing older video files, though I mainly used it for audio extraction. In the latest update (version 24.3.0, released March 2025), Movavi fixed DVD conversion issues and added hardware support for ARM processors on Macs, an update that makes it even faster on newer Mac models. The program also includes compression tools that reduce file sizes without sacrificing quality, which proved helpful when I needed to save storage space.

Why I picked it: simplicity is the strength of Free MP4 Video Converter. It converts MP4 to MP3 cleanly without clutter or unnecessary complexity, which makes it perfect for quick tasks.

OS: Windows
Free MP4 Video Converter delivers straightforward conversion without overwhelming you with options. I tested it with various MP4 files, and it consistently produced clean MP3 output. The preset editor makes it easy to adjust video and audio formats, and the interface feels intuitive enough that I didn't need to reference any guides.

What stands out for me is the unique feature that lets you merge multiple video files into one before conversion, which saved me time when I needed to combine podcast segments. The software also supports many formats, including MP3, FLV, and AVI, which is why I consider it a versatile tool for various conversion needs.

During testing, it ran smoothly on Windows 10 and 11 without any compatibility issues. I would say the converter particularly focuses on doing one thing well rather than trying to be an all-in-one solution. This is quite noticeable in its lack of advanced editing tools; albeit, that simplicity means faster conversions and a cleaner user experience.

Why I picked it: power and consistency put Vidmore on this list. It maintains audio quality even with 4K source files and delivers noticeably faster conversions than most desktop tools.

OS: Windows, macOS

Similar to Movavi, Vidmore Video Converter impressed me with its conversion speed. I tested it with several large MP4 files, and to my greatest shock, the 50x faster processing claim held up in practice. The software handles 4K footage without loss of quality, which matters when you're working with high-resolution source material.

What I also like about Vidmore is how it balances speed with quality. The converter supports full 1080p HD and 4K output, and during testing, I didn't notice any audio degradation in the MP3 files it produced. Beyond the solid output, the interface feels modern and organized, making it easy to find the features you need without digging through menus.

The software also includes editing options that let you trim, merge, and enhance both video and audio quality before conversion. While these tools are basic compared to dedicated editors, they're sufficient for quick adjustments. More importantly, Vidmore works from any device, which adds flexibility when you need to convert files on different systems.

Why I picked it: The GPU acceleration technology earned VideoProc a place on this list. It processes files far quicker than CPU-only tools, and the built-in audio cutter makes quick edits painless.

OS: Windows 7 and later, macOS X 10.6 and later

VideoProc Converter delivers fast, high-quality MP4-to-MP3 conversions with minimal system resource usage. I tested it with several large video files, and the GPU acceleration made a noticeable difference in speed. The software also supports batch processing, letting you convert multiple videos simultaneously without performance drops.

Another upside is how the interface feels very intuitive, making it accessible even for beginners. I particularly liked the audio editing tools that let you merge tracks, adjust volume, and cut sections before conversion. And the best part for me? VideoProc supports a wide range of formats, eliminating the need to convert files twice when dealing with unusual formats. During testing, the software proved reliable and stable as it was able to convert files without crashes or loss of quality.

Why I picked it: I find HandBrake to be very reliable. I picked it because of its open source, which is frequently updated, and its professional-grade audio extraction control that rivals paid alternatives.

OS: Windows, macOS, Linux

After spending a significant exploring HandBrake, I consider it a robust open-source video transcoder that converts MP4 to MP3 with precision. I tested it across multiple projects, and it consistently delivered clean audio output without compression artifacts. The software offers built-in presets that simplify the conversion process, though you can dig into advanced settings for granular control over bitrate and audio channels.

Like most high-end converters, HandBrake also offers support for hardware acceleration. When I enabled GPU encoding, the conversion speeds improved dramatically, especially with large files. Similarly, the software also handles batch processing, letting you queue multiple videos for conversion without babysitting the process. On top of that, it's completely free with no hidden costs or trial limitations.

The latest update (version 1.10.2, released September 2025) fixed crashes that typically occurred during high-depth video encoding and updated the SVT-AV1 encoding stack to version 3.1.2. HandBrake also introduced support for the VideoToolbox AV1 hardware decoder and added a preference to run custom actions when the queue completes, a move that streamlines workflow automation.

Why I picked it: VLC made the cut because most people already have it pre-installed. It converts MP4 to MP3 reliably without requiring additional downloads or complex setup.

OS: Windows, macOS, Linux, Android

VLC does more than play videos; the industry veteran converts multimedia files too. I used it to extract audio from several MP4 files, and the process proved straightforward once I learned the steps. You access conversion through the Media menu, select Convert/Save, add your MP4 file, and choose MP3 as the output format. The conversion is quick, and VLC preserves audio quality throughout.

Meanwhile, like most high-end converters, the software supports batch conversion, which saved me considerable time when I needed to convert multiple files at once. I also appreciate that it works across virtually every platform, making it a versatile choice regardless of your operating system. VLC also handles most file formats without error feedback, and since it's free and open-source, there are no trial limitations or watermarks to worry about.

However, if it’s not much of a concern for you, VLC is primarily a media player, not a dedicated converter. This explains why the conversion interface feels hidden and less intuitive than purpose-built tools. During testing, I found that conversion settings require manual adjustment each time, which may become tedious for regular use.

Freeware, shareware, and more are available for some of the best online converters. There's no need to download these as you can simply visit a website and use them as long as you have an internet connection.

Why I picked it: Online Converter is versatile! It’s the type of tool that works as a video, audio, document, and ebook converter all in one place, handling over 50 source formats with ease.

OS: any (browser-based)

Online Converter delivers straightforward conversion without complications. I tested it with various MP4 files, and it handled everything smoothly. The tool quickly identifies the target format, and conversion happens fast enough for most use cases. I also like how it includes settings to adjust screen size, frame rate, and even mirror or flip the video before conversion. Even though, these features may not be relevant for audio conversion, they could easily come in handy for other use cases.

Meanwhile, the interface feels clean and uncluttered, focusing on getting the job done without getting distracted by unnecessary features. During testing, files under 100 MB converted in under 2 minutes on average. The converter also supports documents and ebooks, adding versatility if you need to convert other file types.

While it lacks advanced editing tools, that simplicity makes it perfect for quick conversions when you don't want to install software. The best part for me, however, is that it works entirely in your browser, eliminating downloads and setup time.

Why I picked it: Convertio wins in terms of convenience. It works entirely in your browser, supports 300+ formats, and handles conversions up to 100 MB without requiring account creation.

OS: any (browser-based)

Convertio makes online conversion effortless, at least from my observation. I tested it with various MP4 files, and the process proved straightforward every time. You upload your file (or pull it from Google Drive or Dropbox), select MP3 as the output format, and conversion begins in seconds. The interface feels clean and uncluttered, focusing on getting the job done quickly.

What I like most is how it handles file security. Convertio automatically deletes uploaded files immediately and converted files after 24 hours, ensuring your content stays private. Additionally, the conversion happens in the cloud, so it doesn't slow down your device. During testing, I found that files under 100 MB convert quickly, typically in under 2 minutes.

The free version works well for occasional conversions, but frequent users will hit the 100 MB file size limit, and may be required to invest for full functionality. For larger files or batch conversions, the paid plans start at around $10 per month, which is a considerable value-packed fee for those that convert regularly.

Why I picked it: I picked it because it offers a three-step process that converts MP4 files to MP3 in seconds, supports files up to 50 MB, and automatically deletes files after conversion.

OS: any (browser-based)

AnyConv delivers quick conversions with minimal fuss. I tested it with multiple MP4 files, and the process proved reliable each time. You upload your file (up to 50 MB), select MP3 as the output format, and the conversion happens immediately. The interface feels straightforward, eliminating unnecessary steps between you and your converted file.

What impressed me during testing was how fast conversions were completed; most files finished in under a minute, which is a competitive time when compared with other online converters. AnyConv further supports over 300 file formats across different categories, making it versatile beyond just video-to-audio conversion.

Meanwhile, the platform takes security seriously, deleting all files immediately after conversion to ensure your content stays private. During testing, I appreciated that no account creation was required, letting me convert files without sharing personal information. The free version allows up to 60 file conversions per hour, which should be enough for most users.

Why I picked it: FreeConvert’s generous file limit caught my attention. The free version supports files up to 1 GB, includes advanced customization options, and lets you adjust audio parameters before conversion.

OS: any (browser-based)

FreeConvert delivers reliable online conversion with more flexibility than most competitors. I tested it with files ranging from short clips to full-length recordings, and it handled them all smoothly. More interestingly, the interface lets you adjust audio codec, fade in/out, and other parameters before conversion, giving you full control over the final output.

What impressed me during testing was how the free version supports files up to 1GB, which is significantly more generous than most online converters. The conversion speed further proved competitive, and I didn't encounter the crashes or quality issues that plague some free tools.

FreeConvert also includes basic editing features, such as trimming, which saves time when you only need part of the audio. And the best part? The tool works entirely in your browser, eliminating the need for downloads or installations. Not to mention that every file is protected with 256-bit SSL encryption and automatically deleted after a few hours, ensuring your content remains secure throughout the process.

Why I picked it: ConvertFiles stores converted files for 1 hour and offers a simple interface that works seamlessly on smartphones for on-the-go conversions.

OS: any (browser-based)

Above all else, ConvertFiles handles MP4 to MP3 conversion quickly and efficiently. I tested it on both desktop and mobile devices, and the simple UI made it equally easy to use on my smartphone. The converter supports files up to 250 MB, which covers most casual conversion needs.

What stands out is the one-hour storage feature. After conversion, your file remains available on the server for an hour, giving you time to download it from different devices or locations. While testing, I found this particularly useful when I started a conversion on my phone but wanted to download the results later on my computer.

Meanwhile, the platform supports over 300 file formats beyond audio and video, making it versatile for a wide range of conversion needs. Even better, ConvertFiles works entirely in your browser without requiring software installation or account creation, which streamlines the process considerably.

There might be instances when users might need to convert their MP4 files to MP3 on the go on their smartphones. It is especially the case when users want fast file conversions where there is no need to sit down with their laptop or PC. So, here are some of the best free MP4-to-MP3 converters that you can use for Android and iOS.

Why I picked it: Media Converter's strength lies in its comprehensive format support. I liked it because it handles any video and audio format, includes compression tools, and functions as a universal video player.

OS: iOS

Media Converter delivers reliable conversion on iOS devices. I tested it with various file formats, and it handled everything I threw at it without compatibility issues. The app supports all major video and audio formats, which eliminates the frustration of finding unsupported files.

Beyond conversion, the app includes video and audio compression tools that help reduce file sizes when storage space is limited. During testing, I found that the compression balanced the quality and file size effectively. The app also functions as a media player, letting you preview converted files without switching to another app.

Furthermore, I find the program interface to be very clean and well-organized, making navigation simple even for users unfamiliar with file conversion. At the same time, conversion speed proved adequate for mobile use, though the paid pro version unlocks faster processing and removes conversion time limits.

Why I picked it: Video to MP3 Converter is both Versatility and mobile friendly. I liked it because it includes an integrated MP3 cutter for creating ringtones, and supports variable bitrate for quality control.

OS: Android

Video to MP3 Converter handles mobile conversion efficiently. I tested it on several Android devices, and it performed consistently well across different hardware. The app extracts audio from MP4 files without compressing the output, preserving the original audio quality throughout the conversion process.

What I like most is the built-in MP3 cutter that lets you create custom ringtones or trim audio sections without switching apps. The interface also feels straightforward; you select your video, choose the conversion quality, and the app handles the rest. Conversion speed proved fast enough for most use cases, though larger files occasionally caused some lag.

The app supports variable bitrate, giving you control over file size and quality balance. During testing, I found that the default settings work well for most situations, but the ability to adjust the bitrate is helpful when storage space is limited.

Why I picked it: this tool combines MP4 to MP3 conversion with advanced audio editing tools like compression, trimming, and ringtone creation, making it perfect for users who need more than basic conversion.

OS: iOS

MP3 Converter: Audio Tools impressed me with its comprehensive feature set. I tested it with various MP4 files, and the conversion proved fast and reliable. What particularly stands out is how the app goes beyond simple extraction; it includes audio compression, trimming, denoising, and even equalizer adjustments.

Another thing I like about this tool is its all-in-one approach. You can convert your video to MP3, then immediately trim unwanted sections, adjust audio levels, or create custom ringtones without switching apps. While testing, I found the compression feature particularly useful for reducing file sizes while maintaining quality.

Meanwhile, the interface feels modern and intuitive, with clear buttons and straightforward menus. The app supports multiple import methods, including the Files app, Photo Library, and Music collection. You can extract audio from local videos or audio files on your device, with no internet connection required for the core conversion features.

Why I picked it: MP3 Video Converter wins at simplicity. I picked it because it offers one-click conversion, lets you choose the codec, and includes an album-creation feature to organize your converted audio files.

OS: Android

MP3 Video Converter handles file conversion with minimal complexity. I tested it on multiple Android devices, and it consistently delivered quick results. The one-click conversion process eliminates unnecessary steps; you can simply select your video file, choose the codec, and conversion begins immediately.

What I like about this app is the album creation feature. After converting multiple files, you can organize them into albums directly within the app, making it easy to manage your music library. The interface feels clean and uncluttered, which makes navigation simple even for first-time users.

The app supports various bitrates, allowing you to control output quality and file size. During testing, conversion speed proved adequate, though the app occasionally lagged with huge files. The codec selection feature adds flexibility when you need specific audio formats for different devices.

Why I picked it: multiple reviews suggest that It's one of the fastest converters on Google Play. Truly, it handles conversions quickly while including trim, resize, and ringtone creation features.

OS: Android

Video MP3 Converter impressed me with its conversion speed. I tested it with various video files, and it consistently outperformed many competitors in raw processing time. The app converts video files to MP3 or AAC formats with minimal wait time, making it ideal for users who need quick results.

Furthermore, the app supports various video formats, including 3GP, FLV, and MP4, giving you flexibility with different source files. It also includes basic editing tools for trimming and resizing videos before conversion. The ringtone creation feature works smoothly, letting you create custom ringtones from any converted audio file.

When it comes to choosing an MP4-to-MP3 converter, I keep coming back to Movavi Video Converter more than any other tool. It's fast, reliable, and polished enough to handle everything from quick conversions to batch processing without breaking a sweat. For me, Movavi’s Superspeed technology makes a real difference when you're working with large files, and the interface stays out of your way.

That said, I keep a few other converters in rotation depending on the situation. When I need a free, no-strings-attached option and don't mind a slightly technical interface, HandBrake delivers solid results. For quick conversions when I'm already using VLC for playback, the built-in converter works fine for simple tasks.

When I’m on a device without installed software, Convertio is the online tool I reach for. It works in any browser, integrates with cloud storage, and handles smaller files quickly. If the file size is bigger, FreeConvert is the better option thanks to its generous 1 GB limit and adjustable audio parameters. For on-the-go tasks, Video MP3 Converter on Android and Media Converter on iOS deliver the fastest and most flexible mobile conversions.

If you convert regularly, desktop tools always win. They process larger files faster, avoid upload limits, and maintain higher audio quality. Online tools like Convertio, Online Converter, and AnyConv work for quick, one-off tasks, but they typically hit size caps quickly with the exception of FreeConvert.

On the other hand, mobile apps are convenient for small clips but aren’t built for heavy lifting. Generally, if your priority is speed, reliability, and clean output every single time, Movavi Video Converter remains an exceptional choice. It’s not free, but the reliability, and time it saves makes the investment worthwhile for anyone who converts files frequently.
