The software allows converting more than 420+ video and audio file formats to MP3. You can also adjust various parameters of the output MP3 file, including bitrate, sample rate, and channels, to get the desired output quality and size.

Audio Converting Features in VideoProc Converter

VideoProc Converter uses advanced algorithms to ensure that the quality of the converted MP3 file is as close to the original as possible. The batch conversion feature can help save time and effort when converting multiple video or audio files at once. Despite being a commercial tool, this MP3 converter for Windows includes a free trial so you may try it out before buying.

2. MediaMonkey

Best Free MP3 Converter for Windows 10

Platform: Windows and Android

MediaMonkey Convert MP3

MediaMonkey is a popular media player and audio library application for Windows. Besides media organizing and managing, it also serves as the best free MP3 converter for Windows 10. This software can help convert files in your library to various formats, including MP3, OGG, WAV, FLAC, etc. It also provides customizable output settings, such as sample rate and channels.

However, for MP3 conversion, customizable MP3 settings require a gold license. Otherwise, you'll be stuck with the default MP3 conversion settings, which include a time-limited LAME MP3 encoder. Besides, an additional codec pack is also required for AAC (.m4a, .m4b), H.264 (.mp4, .m4v, .mkv), and MPEG4 (.avi) files.

One of the Best MP3 Converter Programs

Platform: Windows, Mac, and Linux

MP3 Converter - FFmpeg

  • A large array of plug-ins
