Video to MP3 converter FAQ

Are my videos uploaded?
No. Your browser reads the video and decodes only its sound on your device, then encodes the MP3 there. From this site, your browser downloads only this page, its four scripts and the small site icon. The page also loads Google Analytics, which counts visits and never receives your files.
Do I need an account to download?
No. There is no sign-up or login on this site. The download button saves the converted file straight from your browser.
Which bitrates and sample rates can I choose?
MP3 at 128, 160, 192, 256 or 320 kbps, at 44.1 kHz or 48 kHz. WAV is 16-bit at the same two sample rates. Mono files stay mono and stereo files stay stereo. Files with more than two channels are mixed down to stereo.
Which videos work?
In our tests (Chromium, 2026-10-08), these converted: MP4 and MOV with H.264 or HEVC video, M4V, MKV, and WEBM, with AAC, MP3, Opus, Vorbis or uncompressed PCM sound. Two did not: a video whose sound is AC-3 (Dolby Digital), which the browser could not decode, and a video with no sound track. The kind of video picture does not matter, because only the sound is decoded. If your browser can't decode a file, the page says so.
Does the MP3 sound worse than the video?
The sound in most videos is already compressed (usually AAC), and MP3 is compressed again, so a little more detail is lost. A higher bitrate keeps more of it. If you pick WAV, the decoded sound is saved without further compression, in a larger file.
Are titles kept?
If the video has title, artist, album, year, track or genre tags (MP4, MOV and M4V can carry them), they are copied into the MP3. In our test, the title and artist of an MP4 came through. Most phone and screen recordings have no such tags, so the MP3 has none either.
Why is the MP3 a little longer than the video?
MP3 encoding adds a short silence at the start and pads the end to whole frames. In our tests the MP3 from a 10-second video decoded to 10.031 seconds. WAV keeps the exact length.
Is there a limit on video size?
This page sets none, but your device does. The whole video file is read into memory before its sound is decoded, so the file size matters, not only the length, and videos are much larger than audio files. With the browser limited to 1 GB of memory, a 100 MB video converted in 7 seconds and a 250 MB video in 15 seconds; a 500 MB video still converted but took 5 minutes. Chromium also refuses any file larger than 2,145,386,496 bytes (about 2 GB), whatever the memory; we measured that limit here. Phones usually have less memory to spare than computers. For very large videos, use a computer with more free memory.
