Audio Converter
AudioConvert audio between MP3, WAV, M4A and more.
Audio Converter moves audio between formats when something insists on a specific one — MP3 for a player that won't take anything else, WAV for an editor, or a compressed file to save space. Drop the file in, pick the output, and the decode and re-encode happen on your own device. Nothing is uploaded, so interview tapes and unreleased tracks aren't sitting on someone else's server.

Frequently asked questions
How do I convert WAV to MP3?
Drop the file in, choose MP3 and a bitrate, and it's encoded on your device. WAV files are enormous — often ten times the size — so this is usually the last step before publishing or emailing audio.
What bitrate should I use?
128 kbps is plenty for spoken word like a podcast or an interview and keeps the file small; 192 or higher suits music, where the extra data actually shows. Going higher than the source was recorded at adds size without adding quality.
Can I convert several files at once?
Yes — drop in a batch and they're all converted with the same settings, returned as a zip with your original filenames. The batch counts as a single run against the daily free allowance.
Which formats can it read?
MP3, WAV, M4A, OGG, AAC and FLAC in; MP3 or WAV out. Decoding uses your browser's own audio engine, so anything it can play, this can convert.
