How to Convert FLAC to MP3

Edited by Pat Bitton

August 28, 2019

FLAC, or Free Lossless Audio Codec, is an audio format that compresses music files without losing any data. However, as is the case with most lossless formats, the files are often quite large and can fill your storage space with just a few albums. Also, the FLAC format is not widely supported on mobile devices, so you might want to turn your FLAC files into the more widely supported MP3 format to be on the safe side.

There are two main ways to convert files – by using a desktop program or an online service. Check out the guide below to learn more about these conversion options and the differences between FLAC and MP3 files.

How to Use Movavi’s FLAC-to-MP3 Converter

An easy way to convert your files is by using Movavi Video Converter. This powerful conversion software for Windows and Mac can help you not only with changing FLAC to MP3 but also with multiple other media file conversion and compatibility issues. Just download the appropriate version of Video Converter and follow the guide below.

Install the Movavi Converter

Download and run the Movavi Video Converter installation file, and follow the on-screen instructions to set up the app.

Add FLAC Files You Want to Transfer

Click Add Media, select the Add Audio option and choose the audio file for which you would like to change the format. You can also add a batch of files to perform mass conversion. Movavi Video Converter supports a wide range of formats, so you can not only transcode MP3 to AAC, WMA, and other formats but also do the reverse operation and convert MP3 to FLAC, although it won't improve the sound quality because of the specifics of the MP3 format.

Select the Output Format

Open the Audio tab, click on the MP3 group, and select the bitrate that best suits your needs. Since you're converting from a lossless audio format, higher bitrates (like 320 kbps) will certainly retain more quality, but the output files will be larger than those with lower bitrates.

Switch the Format from FLAC to MP3

Check the output folder in the Save to field and click the Folder button if you want to specify another path, then press Convert to transform your FLAC files to MP3. Once conversion is done, the destination folder will open automatically.

FLAC vs. MP3 – Comparing Formats

MP3 vs. FLAC: which one is better? One of the main advantages of FLAC is the sound quality. However, FLAC is not supported by all media players, and the file size is just too large. If you want to play your audio files on different devices and save some storage space, then definitely choose MP3 over FLAC.
