Frequently asked questions
Which conversions are supported?
Three: WAV to MP3 (320 kbps CBR), AIFF to MP3 (320 kbps CBR), and WAV to FLAC (lossless, compression level 5). Pick the one you want with the buttons above the dropzone.
Is this audio converter free?
Yes. No signup, no account, no payment. The entire conversion runs in your browser, so the file never leaves your computer.
What bitrate is the MP3 output?
320 kbps CBR. That's the highest standard MP3 bitrate, which is what most platforms and DJ pools accept for promo uploads. Sample rate and channel count are preserved from the source.
Is the FLAC output lossless?
Yes. FLAC is a lossless compression format, so the encoded file is bit-perfect identical to the source WAV when decoded. It's typically 40 to 60% smaller than the WAV without any loss in quality. Compression level is 5, which is the libFLAC default and a fair balance between encode time and file size.
Does my file get uploaded anywhere?
No. The WAV is decoded locally with the browser's Web Audio API and encoded to MP3 by a pure-JavaScript encoder running on your machine. The output is offered as a download. No file ever touches a server.
How big a WAV can I convert?
Limited by your browser's available memory rather than a hard cap. Most desktop browsers will handle a 1 to 2 hour DJ mix at 44.1 kHz / 16 bit (around 1 GB WAV). On mobile, stick to single tracks rather than full mixes for safety.
How long does the conversion take?
Encoding speed depends on your CPU. Rough estimates on a modern desktop at 44.1 kHz stereo:
- Single track (4 to 5 min): ~15 to 30 seconds
- 30-minute mix: ~2 to 4 minutes
- 60-minute mix: ~4 to 8 minutes
Older laptops and mobile devices are noticeably slower. The progress bar moves in real time so you can leave it running and check back when it's done.
Which browsers are supported?
Every modern browser that supports the Web Audio API: Chrome, Edge, Firefox, Safari, Arc, Brave, and others. No WebAssembly, no SharedArrayBuffer, no eval, so privacy-focused browsers with strict security policies work fine.
