Turn a big WAV, AIFF or OGG into an MP3 you can actually send.
Free WAV to MP3 converter in your browser. Drop a WAV, AIFF or OGG, get an MP3 small enough to send. Your file never leaves your device.
Same converter, two jobs.
The best an MP3 can be. Pick it when you want the top MP3 setting and size isn't the problem, like batch-converting a folder of bounces without opening your DAW. It doesn't promise a size: past roughly 6 to 7 minutes, expect more than 16 MB.
Pick it when the file has to get through chat, email or a client's inbox. It finds the best quality that still fits under 16 MB, then shows you the bitrate and size. A 12 minute stereo WAV would be about 27 MB at 320 kbps. Here it came out at 160 kbps and 13.7 MB.
Three steps, no account. AIFF and OGG work the same way.
Max quality for 320 kbps, or Convert to sharing size for an MP3 under 16 MB.
WAV, AIFF or OGG, one or several. The conversion runs on your device.
Each file downloads automatically, and the page shows its bitrate and size.
No account, no upload, no cost. The conversion runs in your browser, so an unreleased bounce never lands on someone else's server.
Check it yourself: open your browser's network tab, convert a file, and watch. Your audio is never in any request. The only outside call is a tiny anonymous counter that adds one to the number on the cassette.
No. The conversion runs in your browser, on your device. There's no account and your audio is never sent anywhere. The only thing the page sends out is a tiny anonymous ping to a public counter (the number on the cassette) when a file finishes, with no file name, no file details and nothing about you. Don't take our word for it: open your browser's network tab, convert a file, and watch.
It looks for the best quality that still fits under 16 MB, then shows you the bitrate and size when each file is done. A 12 minute stereo WAV would be about 27 MB at 320 kbps. Here it came out at 160 kbps and 13.7 MB. If it has to go below 64 kbps, it switches to mono. The 16 MB target is for files you want to send: chat, email, a client's inbox. WhatsApp is one place people share files. We can't speak for any app's limit, so check yours.
No. 320 kbps is the most an MP3 can offer, but MP3 is lossy: a smaller file made by discarding audio data, not a copy of your WAV. Keep the WAV as your master, and send it or the stems when someone needs to mix, master or process the track.
WAV, AIFF, AIF and AIFC, as PCM at 8, 16, 24 or 32-bit, plus 32-bit float. OGG and Opus files (Vorbis or Opus audio) work too, because your browser decodes them. No re-export needed. Compressed AIFC isn't supported. MP3 files aren't accepted: re-encoding an MP3 only loses more quality, so start from your WAV or AIFF. Sample rate and channels are handled for you: 44.1 and 48 kHz are kept, other rates like 96 kHz are resampled to 44.1, and anything over two channels is downmixed to stereo.
In sharing size mode, past roughly an hour of audio it stops with an error instead of handing you something that won't fit. Split the track into parts and run them again. Max quality never promises a size, and at 320 kbps a track over roughly 6 to 7 minutes will be bigger than 16 MB. We haven't tested a maximum file size, so we won't quote one.
AIFF tags and artwork are dropped. We haven't verified what happens to WAV tags, so assume nothing and re-tag after converting.
We've tested in Chrome. Other modern browsers may work, but we haven't verified them, so we won't say they do.
Dubdeck is built on Mediabunny, the open-source library by Vanilagy that reads your file and writes the MP3. The encoder is Mediabunny's build of LAME, running as WebAssembly.
