MP3 is the format every phone, car, editor and upload form accepts. Drop in a voice memo, a WAV from a recorder, a FLAC album track or a video, pick a quality, and save an MP3. The conversion runs on your own device, so the file is never uploaded.
Your file never leaves your device. Nothing is uploaded.
Drop an audio or video file here
Drop any audio or video file up to 500MB. It's converted to MP3 on your device.
Conversion runs on FFmpeg, compiled to WebAssembly, inside this browser tab. Licences and source
Almost any audio or video file: M4A, WAV, FLAC, OGG, Opus, AAC, WMA, AIFF and AMR, plus MP4, MOV, WebM, MKV and AVI video. For a video, it keeps the sound and drops the picture.
Nowhere. The converter runs inside your browser tab, so the file is read and converted on your own device and saved straight back to it. It is never uploaded to Wave or anyone else, and we never see its name or contents.
128 kbps for speech, 192 kbps for most music, 320 kbps (the MP3 maximum) when you want the highest quality. A higher bitrate than the source had only makes the file bigger.
No daily limit and no account, because your own device does the work. Each file can be up to 500MB; on phones, files over 200MB may run out of browser memory.
