Best Audio Converter Software in 2021

1. Free HD Video Converter Factory - Best Free Audio Converter for Windows

Don’t get confused by the name. Free HD Video Converter Factory is the de facto best audio converter software available for Windows users. With full support for all the popular audio formats and even the rare ones, the software can meet all your audio conversion needs, be they FLAC to MP3, WAV to MP3, or the general video to audio conversions. Moreover, it makes converting and compressing audio files a breeze. For high-demanding audiophiles, it also lets you edit basic audio tags and customize audio parameters as you want. All features are free and easy to use without limits. The only drawback is that it is compatible with Windows solely.

2. Audacity (Windows, macOS, Linux)

Audacity is a free, open-source, cross-platform audio software for handling various audio tasks. And it is one of the top audio converters to deal with audio files losslessly (It supports file exporting to 16-bit PCM WAV and AIFF). Audacity also works well for simple audio conversions. It supports MP3, WAV, AIFF, AU, and OGG inputs and MP3, WAV, and OGG outputs. If you have installed FFmpeg plugins, you will have more conversion options. But the biggest advantage Audacity has over others is that it allows you to edit music files like professionals before conversions. However, due to its dull and complicated interface, Audacity is the better choice for experienced users.

3. VLC (Windows, Mac, Linux, Android, iOS)

If you have a VLC installed on your device, you can take advantage of this very app to convert audio files too. Yes, you heard it right. Besides being a universal media player, this free open-source program can also serve as a decent audio converter for basic audio conversion needs. It can work on major audio formats and convert them to 10 output formats, including MP3, AAC, WAV, FLAC, OPUS, etc. Additionally, it allows simple CD ripping as well. However, the conversion feature is not shown evidently as the playing function. New users may want to follow some tutorials before converting on their own. [For reference, please check VLC Converter.]

4. Freemake Audio Converter (Windows)

Freemake Audio Converter is a Windows-based audio converter that is extremely easy to use. Simply add the audio, select output format, click convert, and done. Freemake has wide support for all the major audio file types that can be outputted to MP3, WMA, WAV, FLAC, AAC, and OGG. Yet, the freeware only allows up to 3 minutes of audio conversion. To break the limits, you’ll have to purchase Freemake Infinite Pack. Freemake also has a relatively slower conversion speed compared with other converters. Another thing to note is that there could be bundleware downloaded to your PC through the setup. So be sure to watch for that during the installation.

5. MediaHuman Audio Converter - Best Free Audio Converter for Mac

Fancy a straightforward free audio converter program without complicated features and confusing interfaces? MediaHuman Audio Converter is the best of this genre. No need for a tutorial, MediaHuman Audio Converter can take you to convert between all key audio formats, including WMA, MP3, AAC, WAV, FALC, OGG, AIFF, and so on, easily. Apart from that, it also makes extracting audio from videos possible. Moreover, converting multiple files will automatically activate the batch conversion mode that would significantly boost the conversion process. And if you use iTunes, you can choose to export the converted files to your iTunes playlist directly. One more benefit is that MediaHuman Audio Converter is multi-language supported.

6. VSDC Free Audio Converter (Windows)

VSDC Free Audio Converter is the program that would make your audio conversions easy and smooth, for all conversions will take place in a very simple and intuitive interface. However, it has limited support for input and output formats, covering only some mainstream formats such as MP3, WMA, AAC, M4A, AMR, OGG, WAV, AIFF, and AU. Yet, on the other hand, it enables you to convert audio files from online URLs, which is an uncommon feature you don’t get from most other converters. VSDC Free Audio Converter also comes with a tag editor that can be used to edit the title, author, album, genre, year, etc. of your music file.

7. Hamster Free Audio Converter (Windows)

It looks like an audio converter for Android, but it’s not. Hamster Free Audio Converter is in fact a top free audio converter for PC Windows. And it isn’t hard to use at all. However, it is a little weak in the file input support (covers major audio formats, though). But it allows you to output files to not only basic audio formats like MP3, AAC, and WAV but also a variety of device presets. Another benefit the freeware offers is that you can merge audio files if you want. Hamster Free Audio Converter is a simple program, and it lacks some advanced features that many other converters usually have.

8. Switch Audio File Converter Software (Windows, Mac, Android, Kindle)

Switch Audio File Converter Software is a feature-rich program that does a very good job in converting nearly all types of audio files, including the rarest ones, into 35 output formats (the widest support we’ve ever seen). It can also extract audio from DVDs and video files. What’s more, Switch comes with an audio normalization function that can automatically enhance the audio quality and make it clearer. Nevertheless, it has a rather slow conversion speed. It cannot batch convert more than five files, hence making the conversion a time-consuming process. The last thing to note is that the free trial version of the software is for non-commercial home use only.

9. FFmpeg (Windows, macOS, Linux)

Recommended by many advanced users, the free open-source FFmpeg can do a lot of audio-related works, including audio conversion, audio recording, and audio streaming. We don’t know how many audio formats it supports. But during our tests, it recognized and processed all the audio files (both common- and uncommon-seen) we threw at it. However, one important thing to note is that, unlike other GUI software, FFmpeg performs tasks through the command line instead, giving power users much flexibility to customize conversions to their own preferences on the one hand while causing troubles for rookies on the other hand. In short, FFmpeg is for users who are comfortable with shell scripting.

10. Fre:ac - Free Audio Converter (Windows, macOS, Linux, FreeBSD and Haiku)

Fre:ac - Free Audio Converter, as the name suggests, is a freeware converter for audio conversions. It is compatible with a variety of audio formats and can convert freely between MP3, AAC, FLAC, WAV, and many others. But what really outshines others is its integrated CD ripper that can easily rip your audio CDs to MP3 or M4A. You can even convert the whole music libraries while retaining the folder and filename structure. Yet, take note of that Fre:ac will convert audio files to lower bitrate, which means the quality of the converted file will drop to some degree. So you’d better start off with higher bitrate audio source files.

11. AIMP (Windows, Android)

Best known as a freeware audio player for Windows and Android, AIMP also features an impressive audio converter that can take care of various types of audio conversions. It can convert a total of 27 audio formats to 9 different popular audio files (APE, MP3, FLAC, WAV, etc.). And it can do it with multithreading encoding. Another function seldom mentioned but might have a use is that it can output all sources into a single result (with the ability to generate a CUE Sheet) and vice versa. In addition, it’s got an advanced tag editor. To access the AIMP Audio Converter, open AIMP > MENU > Utilities > Audio Converter.

12. Helium Converter (Windows)

Helium Converter is a free, lightweight audio converter for Windows only. It is a bit like Switch in the way that they both have a very simple-to-use interface. Users with little knowledge of conversion stuff can easily handle this converter without hassle. As for conversion, it pales by comparison with some other converters, for it does not have wide support for input formats. However, it indeed covers the most basic audio formats that can be converted to FLAC, WAV, MP3, WMA, and even MP4. Helium doesn’t have many fancy features, either (no audio editing or tag editing). But I guess that’s why it holds a special place in some users.
