What to know before you convert
Lossy or lossless?
MP3, M4A, OGG and Opus are lossy: small and great for listening. WAV, FLAC, ALAC and AIFF are lossless: bigger, but every bit is kept, which is what you want for editing, DJing and archiving.
Private by default
Files up to 100 MB are converted inside your browser with WebAssembly. Nothing is uploaded, so it's fast and private, even on public Wi-Fi.
Frequently asked questions
Which formats can I convert?
Input: MP3, WAV, FLAC, M4A/AAC, ALAC, OGG Vorbis, Opus, AIFF, WMA, AMR, AC3, CAF and WebM audio, plus MP4, MOV, MKV, WebM and AVI video. Output: MP3, WAV, FLAC, M4A, ALAC, OGG, Opus, AIFF and M4R ringtones.
Can I convert many files at once?
Yes. Add up to 20 files, set one format for all of them or customize each one, then download everything as a ZIP.
Do my files get uploaded?
Usually not. Files up to 100 MB are converted on your own device with WebAssembly, so they never leave it. Larger files, or browsers that can't run the converter, use our servers; those files are deleted automatically after a short time.
What's the maximum file size?
Up to 500 MB per file and 20 files per batch by default. Files up to 100 MB are converted on your device.
