11 Best Free Image Converters [2025]

• The standouts: Movavi Video Converter if you want one program that does a bit of everything, XnConvert if you’re dealing with obscure formats or giant batches, and Pixillion if you just want your files flipped fast without fuss.
• Every converter has its strengths. Some are built for speed, others for tinkering, and a few include bonus perks like compression tools or quick edits.
• Always take the free or trial version for a spin before paying – you’ll know right away if the interface clicks or makes you want to shut the whole thing down.
• Match the tool to the job. Use a lightweight online converter for a quick PNG to JPG, and save the heavyweight desktop software for serious batch image conversion or when you’re in the mood to turn a photo to video.

It’s useful to have one downloaded to your PC to avoid such situations. Check out my list of the best image converters for PC.

Why I picked it: a reliable all-in-one solution with support for 180+ formats, plus handy editing tools like cropping and watermarking.

Movavi Video Converter is a handy tool when you need to change the format of media files, including photos. It is an all-in-one image converter that supports more than 180 media formats. Before converting a picture, the software lets you crop, rotate, add a watermark, or type in some titles. It also works with music and video files, and besides converting photos, it can also turn stills into clips, working as an easy photo to video option. I mainly noticed how smooth the image conversion was.

The application is available for both Windows and Mac, making it a reliable choice if you need image converter software for PC. The software is paid, but you can download the trial version for free and then decide if the full version is worth it. I liked having the chance to test it first.

Why I picked it: excellent for batch image conversion and rare file types, with 500+ formats supported.

This program will save your day if you need to convert a rare image file format. It can read more than 500 image formats and change them into over 70 others. With XnConvert, you can convert multiple images at once, change their size, import folders, and do much more.

The interface might seem complicated if you only want to quickly convert PNG or RAW to JPG, although it can be customized and offers plenty of advanced settings when needed. The software works on Windows, macOS, and Linux. It seemed great to me for handling large sets of images and unusual formats.

Why I picked it: super simple drag-and-drop, plus a neat photo-to-video option for extra flexibility.

A free unlimited image converter for those who need to get their files converted quickly and with minimum effort. Its user-friendly interface is very easy to understand, so even if you have no experience in file converting at all, you will be able to do it without any difficulties. All you do is drag and drop your file to the program and then choose a suitable format from the suggested list. I liked how simple this process felt.

On the other hand, Adapter comes with advanced features, including the ability to act as a simple photo to video tool, as well as custom file and output directories, quality and resolution adjustments, and edits. So experienced users also will like it and will find it quite helpful. Available for Windows 10, Windows 11, and Mac.

Why I picked it: lightweight, fast, and doesn’t bog you down with unnecessary features.

Pixillion Image Converter Software is a high-quality image converter that supports all the popular image formats with a number of rarer ones.

The great thing about this application is that it is really light-weighted and works very fast without any bugs. It’s a perfect tool for those who don’t want to spend a lot of time converting files and need to get the result in a couple of minutes. I liked how quickly it handled my test conversions. The program makes it easy to get results without delay.

Online image converters work essentially the same way as their desktop versions. The obvious advantage of the former is that they do not require any downloading, with a few rare exceptions. A common setback for online services is that they fall behind their desktop counterparts, and you need a stable Internet connection for them to work properly. Try out and choose the best image converter online for you in this section.

Why I picked it: quick browser-based option with extra tools like resizing, compression, and watermarking.

Image Candy allows you to convert images to and from the most popular formats in just two clicks. I appreciated that it also offers extras like resizing, compressing, rotating, flipping, watermarking, and even converting HEIC to JPG. It works entirely in the browser so there’s no need to install anything. Converted files remain available for about 120 minutes, after which they are automatically removed.

Why I picked it: straightforward one-file converter that works fast when you just need a quick result.

A free online image converter that will help you to quickly change the format of your picture. It seemed very straightforward to me and I had no trouble getting the result. The free version doesn’t have a batch converting option, you can process only one image at once. On the other hand, it works pretty fast. It’s good to have this program if you need to convert an image from time to time for personal needs and don’t need complicated software with advanced settings.

Why I picked it: dependable online service with wide format support and useful compression features.

One of the best free image converters online with the paid version that supports the most widely used photo and graphic formats. With Zamzar, you can convert images up to 50 MB and run bulk conversions. You’ll get a link with your processed images to your email or on the download page.

The only little inconvenience is that you need to download your converted files individually, even if you uploaded them together at once. However, free users face limits in speed, number of conversions per day, and lower priority compared to paid users. It seemed reliable to me for quick, occasional conversions. In August 2025, Zamzar improved its compression tools, giving more control over the balance between quality and file size.

Why I picked it: clean interface, lots of format support, and it makes tasks like PNG to JPG super easy.

Convertio is an online conversion tool available for free. It supports almost all popular media formats, including image formats. Before the conversion, the service allows you to crop your picture, select the DPI, and resize the image. I found the interface easy to navigate and the process felt quick.

Popular formats such as PNG to JPG or TIFF to PNG are handled easily. Note that if you don’t have a paid subscription, Convertio has some limitations: the maximum file size is 100 MB, and you can convert up to 10 files per day.

Why I picked it: packed with advanced settings and flexibility, great for when you want more control.

The next option to change image formats online is to use Online-Convert.com. This service allows you to convert files fast as well as to apply some basic options, like changing a preset and screen size, cut and flip your image. I liked how many advanced settings were available compared to other online converters. Note that the free plan has some restrictions: the maximum video size is 100 MB and the number of concurrent conversions is limited. If you want to remove these limitations, the service offers a few subscription plans. It also offers an educational account, which gives verified students and teachers access to premium tools for free.

Mobile image converters allow you to conveniently change the file formats on the spot in a matter of seconds. Both Android and iOS platforms provide a great number of apps to choose from, making it more challenging to handpick a service that suits your personal needs. So, I have made a selection of some of the best free image converter apps for Android and iOS you can try out.

Why I picked it: easy-to-use iOS app with smooth sharing and AirDrop integration.

The app can convert from and to the most popular image formats. You can try it out for free, and if you are a professional, you can opt for the Premium Pass for more advanced options. The interface is easy to understand, and it seemed very convenient to me for quick tasks. You can share and view your post-conversion images immediately, browse through your previously converted files, or move the files to another device via AirDrop.

Why I picked it: solid Android choice with support for 200+ formats and quick batch processing.

Image Converter is an Android service that supports over 200 image formats. It has an easy-to-use interface fitting for beginners. The conversion process goes through the server, so you need to be connected to the Internet. I noticed that it worked quickly for smaller jobs, although the speed may slow down when handling many files at once.

After trying out all these converters, I can tell you one thing: there’s no single winner here among image to video converter software options. It really comes down to what you need at the moment. If you just want something fast, straightforward, and browser-based, Image Candy is the one to open.

Need to wrangle a whole folder of oddball formats? That’s where XnConvert or Movavi Video Converter come in. If you’re impatient (like me) and just want your file done already, Pixillion Image Converter is the fastest ticket.

And then there are the tinkerers. If you’re the type who actually enjoys flipping through settings and trying every possible export option, Convertio and Online-Convert are basically playgrounds.

The smartest approach is not to crown a single winner but to try one or two of these and see which vibe works for you. They’ll all do the basics just fine. The best converter is the one that doesn’t make you want to throw your laptop across the room.
