Every direction, one tool
A WAV from a recorder that's too big to send, an M4A voice memo the editor won't take, a FLAC album for a car stereo that only reads MP3 โ audio formats are a compatibility maze. This converter runs the real FFmpeg engine in your browser and goes in any direction: MP3, WAV, OGG, FLAC, and it reads M4A, AAC, OPUS and WMA as input too.
Batch is free and unlimited โ drop twenty recordings and pick up twenty MP3s. Recordings are often meetings, demos and voice notes: exactly the kind of audio that shouldn't visit a stranger's server, and here it never does.
Frequently asked questions
Which format should I choose?
MP3 at 192 kbps for universal playback; WAV for editing software; FLAC to archive without loss; OGG for the smallest decent-quality files.
Does converting MP3 to FLAC improve quality?
No โ lossless formats faithfully store what the MP3 contains, but detail already lost cannot return. Convert to FLAC only to stop future degradation.
Why does the first conversion start slowly?
The audio engine (~32 MB) downloads once and is cached โ after that everything starts instantly, even offline.
