AudioConverter

Free. Runs in your browser.

"This file won't open." I hear that one a lot. AudioConverter is a universal adapter for sound files: pick the format you want on the other end, drop your files on it, press one button.

MP3, WAV, FLAC, M4A, OGG, WMA and more. Pull the audio out of a video too.
Drop a whole folder and it converts everything inside, subfolders included.
The engine runs in your browser. No upload, no waiting on a server, no file-size fees.
Nothing you convert ever leaves your computer.

Why I ask: I might reach out with a question about how to improve this tool, or to mention other cool tools I build. I will never give your email address to anyone else. You only have to do this once per browser.
