Windows users can also have Freemake Audio Converter as their solution to daily audio format conversions.

It has an intuitive interface. Simply add the audio, select the target 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. It can also convert video to audio without a problem.

However, keep in mind that Freemake’s audio converter only allows up to 3 minutes of audio conversion. To break the limits, you’ll have to purchase the Freemake Infinite Pack.

If you already have VLC installed on your device, you can take advantage of this very app to convert audio files too.

Besides being a universal media player, this free open-source program can also be used as a decent audio converter for basic audio conversion needs. It can work with 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.

Unlike Free HD Video Converter and Freemake, VLC as music converter software would require extra steps to finish a conversion. Check out how to convert audio with VLC for more details.

You may have heard of Audacity as a free, open-source, cross-platform audio software for recording and editing audio files. But it’s also one of the top audio converters to deal with audio files losslessly. Once you create a music project, it can export it to 16-bit PCM WAV and AIFF without losing quality.

Audacity also works well for simple audio conversions. It supports MP3, WAV, AIFF, AU, and OGG inputs and MP3, WAV, and OGG outputs. You can have more conversion options if you have installed the FFmpeg plugin. But the biggest advantage of Audacity over others is that it allows you to edit music files like professionals before conversions. In short, Audacity is the optimal choice for experienced users.

X Lossless Decoder (XLD) is what I consider to be the best free audio file converter for Mac for its reliability, usability, and powerfulness. It’s capable of diverse audio processing, including decoding, playing, and of course, converting audio files.

“Lossless” is its hallmark, and you can use it to convert audio that’s not supported on Mac to ALAC and AIFF flawlessly. In addition, it can also transcode audio files to M4A, AAC, and MP3 for smaller file sizes. Thanks to its multi-threaded conversion feature, it can speed up the conversion process for all files at the same time.

XLD has many features worth exploring, such as splitting music cues into single tracks and ripping CDs. It also has a command-line version that can run shell scripts to automate the tasks you need. Although it is an old application, it is still frequently updated today.

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.

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 - the simple interface explains everything!

However, it’s a little weak in the file input support but covers major audio formats, though. 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.

Switch Audio File Converter Software is a feature-rich program that does a very good job of converting nearly all types of audio files, including the rarest ones, into 35 output formats (the widest support I’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. If you’re looking for a one-stop audio conversion tool, then this might be a good option.

However, note that the free trial version of the software is for non-commercial home use only.

Recommended by many advanced users, the free open-source FFmpeg can do a lot of audio-related work, including audio conversion, audio recording, and audio streaming.

I don’t know how many audio formats it supports. But during my tests, it recognized and processed all the audio files (both common- and uncommon-seen) I threw at it. It’s also the best batch audio converter that can convert a folder of audio files all at once.

However, one important thing to note is that, unlike other GUI software, FFmpeg performs tasks through the command line, giving power users much flexibility to customize conversions to their own preferences. But this on the other hand also causes troubles for rookies. In short, FFmpeg is for users who are comfortable with shell scripting.

Fre:ac - Free Audio Converter, as the name suggests, is a freeware converter for audio conversion. It’s compatible with a wide range of audio formats and can freely convert between MP3, AAC, FLAC, WAV and many other formats. But what really makes it stand out from the rest is its integrated CD ripper, which can easily rip audio CDs to MP3 or M4A. You can even convert your entire music library while preserving the folder and file name structure.

However, please note that Fre:ac will convert audio files to a lower bitrate, and while this will reduce the file size, it will also result in a certain degree of quality loss. So you'd better start with a higher bitrate audio source file.

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’s a high-quality MP3 converter that can convert a total of 27 audio formats to 9 different popular audio files (APE, MP3, FLAC, WAV, etc.) and retain the original quality. It can do it with multithreading encoding, meaning it can handle multiple files concurrently. 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.

Helium Converter is a free lightweight audio converter available only for Windows. It’s a bit like Switch in that both feature a very easy-to-use interface. Users with little or no conversion skills can easily use this converter without hassle.

As for conversion, it pales in comparison to some other converters because it does not have a wide support of input formats. However, it does cover the most basic audio formats. As a high-quality MP3 converter software, it can convert FLAC, WAV, WMA, etc. to MP3 while maintaining high quality.

Helium doesn’t have fancy features like audio editing or tag editing. But I guess that is why it holds a special place for some users.
