How to Convert Audio and Video Formats
Phone recordings arrive as .m4a, screen captures as .mp4, and plenty of audio tools will open neither. This converter turns them into MP3 or WAV.

The encoder runs inside your browser. Long files take longer, and the progress bar shows how far along it is.

Download
The converted file is saved with _converted added to the original name, so it will not overwrite your source.
Frequently Asked Questions
Is my file uploaded anywhere?
No. Conversion runs locally in your browser using FFmpeg compiled to WebAssembly. Your audio never leaves your device, which also means you can use it on material you would not want to send to a server.
What output formats are supported?
MP3 and WAV. MP3 uses variable bitrate encoding for a good balance of size and quality; WAV is uncompressed.
Can I convert video?
Yes. Drop in an .mp4 file and the audio track is extracted and converted.
Why does a long file take so long?
The encoder runs on your own machine rather than on a fast server, so speed depends on your device. A phone will be noticeably slower than a laptop.
