Top 10 Best Online Free Audio Converters for Windows/Mac
Just as with digital image formats, the world of audio formats is something of a minefield; an audio track that plays on one device in a certain app may not work on another. As such, you may well want to consider using an audio converter -- or even an online audio converter -- to save a file in a format that is more compatible or convenient. For instance, Apple uses the M4A format for audio files, but MP3 is far more popular, so you may have been seeking an M4A to MP3 converter for the sake of ease.
There are other reasons for wanting to convert between formats. Some lossless formats such as WAV produce huge files that can be difficult to manage, and this is when a WAV to MP3 proves handy. But why restrict yourself to converting between audio formats? If you have a video that you would like to extract the audio from, you can use a video to audio converter to convert from MP4 to MP3.
But where should you start? Here we take a look at the best desktop and online free audio converters to help you change files into the formats that suit you the best.

Available for Windows and Mac, Wondershare Free Video Converter lets you convert a range of videos formats into audio files. It also gives you the opportunity to convert audio from DVDs and save it in MP3 or other audio formats. All popular formats are supported, and to make your life easier there are lots of preset configurations for you to choose from -- but of course you can customize any of the format settings as require. As well as working with audio and video files you have on your computer, Free Video Converter can be used to save audio from YouTube video and other streaming services. The free version of the program has a great deal to offer, but if you upgrade to the Premium edition, you can enjoy additional features such as saving YouTube and other online videos as audio files, and the removal of ads.
You've almost certainly heard of VLC, and even if you don't use it, you probably consider it to be a media player -- which it is. But it also includes the option to convert files between format. Take a look in the Media menu and you'll find the Convert / Save option. You can convert to a range of audio and video formats, but you have more choice when it comes to video. There are numerous ready made format profiles for you to work with, and these can all be customized as required. Files can be converted on an individual basis, or you can queue up several for batch conversion. A very neat and tidy solution for your conversion needs.
All2MP3 is available for Windows and macOS, and it allows for the conversion of audio and video files into MP3, WMA, WAV, M4A, AAC, FLAC and much more. In all there's support for dozens of audio formats, and you can convert over 300 video formats into audio files. There is support for batch conversion, and on top of this there are audio editing options that can be used to join, split and trim files, add special effects and more. You just need to be careful during the installation to decline the optional bloatware -- you have been warned!
MediaHuman Audio Converter does very much what the name suggests, making it easy to convert audio files between formats. There's a simple drag and drop interface and support for all popular formats including lots of handy presets. If you're looking to save YouTube videos as MP3 files, there's also MediaHuman's YouTube to MP3 Converter to consider. This will appeal to many people thanks to the fact it's available for not only Windows and Mac, but also Ubuntu -- and there's even a portable version that you can pop into a USB drive.
VSDC Free Audio Converter has the look of a Windows XP era program, but this does not stop it being a powerful tool. There's support for a wide range of audio formats for both input and output, and you can work with individual files, entire folders of audio, or even M3U playlists. You can also convert music from DVDs or video files, and if there are conversion settings you use frequently, you can save them as a profile for ease of access.
You may well like the idea of being able to convert audio files without the need to install software -- and this is where Online UniConverter (originally Media.io) can help you out. A delightfully accessible and easy-to-use interface means it is very quick to upload a number of files (or just one if you prefer), and use a simple menu system to choose the format you would like to convert to -- and there are more than a dozen to choose from. If you have opted to convert a number of files, you have the option of converting them all to the same format or selecting different formats for each one. There are no complicated options to concern yourself with, just quick and easy results.
Like Online UniConverter, Zamzar is an online converter and it can handle a wide range of file types. It is capable of converting images and office files, but its support for audio and video formats is very impressive. As well as giving you the option of uploading files to convert ready for downloading, the site also lets you convert files that are stored online -- a very handy option!
Another online tool, KeepVid Online Audio Converter focuses on saving extracting the audio from videos and saving it as a new file, or saving existing audio files in a different format. Although this is an online tool, there is no option to work with online content -- you have to upload files from your computer. It's a pretty simple utility, but it gets the job done.
The simply name Convert files may not support as many formats as some other tools we've looked at here (3GP, AC3, AMR, AAC, ALAC, WMA, AIFF, DAUD, FLAC, MP4, MP2, MP3, M4A, OGG, VOC, and WAV), but it is so quick and easy to use, it is well worth checking out. Options are very limited, but if you just need a simple converter, it is ideal.
As the name suggests, Any Audio Converter can handle just about anything you throw at it. It can be used to convert music from CDs, convert audio and videos formats, and also convert the audio from online videos from sites such as YouTube. There are lots of presets to help you convert files for specific purposes, or for playback on particular devices. Just take care during the installation as there is optional software bundled that you may want to decline.
