If you already know you’re going to use an audio conversion program a lot, it’s best to opt for more professional software such as Movavi Video Converter.

Which Free Audio File Converter to Choose?


Supported OS: Any

Supported Formats: more than 1200 formats in total, including all common audio filetypes.

Description: This is one of the oldest free online tools – it’s been out there since 2006. It’s a reliable solution for converting all sorts of digital files – video, text documents, images, and audio tracks. Its only real drawback is the fact that it can only handle up to 150 MB at a time, so it might not be able to handle some high-quality files. However, the number of conversions you can process is unlimited, and the service will store your converted files (up to 5GB per user) on its server for 24 hours. Larger files and additional server space are available for a license fee.


VSDC Free Audio Converter

Description: This is a fast and reliable solution for converting your audio tracks into pretty much any format. The app has advanced export presets, supports downloading audio files from the internet, and can easily delete audio from a multimedia file – or, conversely, extract audio from a video clip. The app has no paid plans and is currently available in 8 languages.


Free Audio Converter

Supported OS: Windows

Supported Formats: AAC, AC3, AIFF, APE, FLAC, M4A, M4B, MKA, MP3, OGG, RA, TTA, WAV, WMA, and more

Description: The name of the app pretty much says it all. A simple, hassle-free app that supports lossless audio conversion with a choice of output presets. It also enables both single and batch mode conversion, which helps you save time – particularly when you need to process a lot of files at once. The developer also offers a similar app specifically for converting YouTube videos into audio files.


Switch Audio File Converter Software

Another universal online tool that could qualify for the best free audio converter. Aside from audio, it can also convert documents, images and videos. Like Zamzar, this service limits the maximum file size it can accept (100 MB for non-registered users, 180 MB after registration). Additionally, you can only convert 10 audio tracks per day free of charge. If you need to do more, you might consider buying one of FileZigZag’s 24-hour plans.

There’s a limit on the file size, too: each track has to be really compact in length – three minutes is your maximum! Freemake can also extract audio from video files (MP4, MPEG and other types). The output file can be saved directly to your Google Drive or Dropbox.


Format Factory

Supported OS: Windows

Supported Formats: MP3/WMA/AMR/OGG/AAC/WAV/FLAC.

Description: If you just need a quick tool for converting your audios and nothing more, MediaHuman Audio Converter is the right choice. It works in a drag-and-drop mode: all you have to do is upload the file you want to transform and choose the output format. The software doesn’t let you customize the output folder or search for album covers. But it’s perfect when it comes to its original function – which is the main point in most cases. 



Supported OS: Windows

Supported Formats: MP4, FLV, MKV, MPG, AVI, MOV, WMV, M4V, 3GP, MP3, WEBM, OPUS, AAC, FLAC, APE, WAV, ASF

Description: This is a simple, user-friendly converter that works with the video and audio formats listed above.
