How to use
When it helps
Phone recordings (M4A), WAV files from recording apps, and OGG or WEBM audio from the web do not play everywhere. MP3 plays on almost every device, which makes it the safest choice.
Unlike video, audio conversion is fast. The browser decodes the whole file and re-encodes it as MP3, so even a 3 minute song takes only a few seconds. Use 192kbps for music. For lectures or meeting recordings, 64 to 96kbps mono is plenty.
WAV is uncompressed, so it is large but easy to work with in editing software. Choose WAV for editing and MP3 for sharing.
FAQ
Which formats can I add?
Any format your browser can play. MP3, M4A (AAC), WAV, OGG, FLAC, WEBM and OPUS work in Chrome and Edge in most cases. WMA and AMR are not supported.
Does converting to a higher bitrate improve quality?
No. Audio that is already compressed does not get better at a higher bitrate. The file only gets bigger.
Are tags like title and album art kept?
No. Only the sound is re-encoded, so tag information is not carried over.
Can it handle long files?
Recordings of 1 to 2 hours work, but they use a lot of memory. On phones, we suggest files under 1 hour.
Are my files uploaded to a server?
No. Conversion happens entirely in your browser.
