How to convert a video to MP3
- Choose videos. Drop files or a whole folder on the page, or press Choose videos. Several files at once are fine.
- Pick a format and bitrate. MP3 plays everywhere. M4A keeps AAC audio untouched when the video already has it. WAV is uncompressed.
- Convert and save. Save each file, or all of them as one ZIP. Chrome and Edge on a computer can also write straight into a folder.
What it reads and writes
- Video files
- MP4, MOV, M4V, MKV, WebM, Ogg, MPEG-TS and 3GP. AVI, FLV and WMV are not supported.
- Audio inside
- AAC (including HE-AAC), MP3, Opus, Vorbis, FLAC and PCM. AC-3 is not supported. A browser that cannot decode a format says so in the list before converting.
- Output
- MP3 at 128, 192 or 320 kbps, M4A (AAC) or WAV (16-bit PCM). Auto uses 192 kbps for stereo and 128 kbps for mono.
- AAC to M4A
- Copied without re-encoding, so there is no quality loss and the bitrate setting does not apply.
- Surround sound
- Mixed down to stereo.
- Speed
- Chrome on a computer encodes MP3 at roughly 70 to 80 times real time, so an hour of audio takes under a minute. A mid-range Android phone manages about 6 to 7 times. Copying AAC into M4A takes seconds.
- Large files
- There is no upload limit because nothing is uploaded. A 1 GB, 52-minute video converted in Chrome on a computer. Results are written to temporary browser storage, so free disk space matters more than memory.
Questions
Are my videos uploaded?
No. The page reads the file in your browser and writes the audio on your device. The page also tells the browser not to talk to any other site (connect-src 'self'), so it could not send a file out even if it tried.
To check, open your browser's developer tools, switch to the Network tab and convert a file. No request carries your video.
Which format should I choose?
MP3 for the widest compatibility. M4A for videos whose audio is already AAC, which covers most phone recordings: the audio is copied as it is. WAV when you want uncompressed audio for editing.
Why is the bitrate greyed out for M4A?
AAC audio is moved into the M4A file without being encoded again, so there is no bitrate to choose. Videos with other audio, such as Opus, are encoded to AAC at the bitrate you pick.
Why was a file skipped or not converted?
Screen recordings and muted exports often have no audio track at all, so there is nothing to extract. Other files fail because the file type is not supported (AVI, FLV, WMV) or because the browser cannot decode the audio inside. The row shows the reason.
Can I leave a conversion running on a phone?
Keep the screen on. A locked screen pauses the page, as seen in Chrome on Android, and the conversion continues when the screen is back on. The Android app converts in the background.
What happens to the results when I close the tab?
They stay in this browser's private storage, which only this site can read, and cannot be opened again from a closed tab. They are removed when you start a new batch or open the page again. Save what you need before closing; the page warns you if something is not saved yet.
