Lossless masters, portable copies
FLAC is the format of choice for buying and archiving music: it's lossless, so it sounds identical to the CD or studio master, but it still takes roughly 25–35 MB per song. Many car stereos, older players, DJ software setups and phones either can't play it or fill up fast. An MP3 copy fixes both problems.
Drop a whole album folder onto WAVR and it converts every track in one batch. It reads the title, artist, album, year, BPM and genre from each FLAC and passes them to the MP3 encoder, so your library stays organised.
How to convert FLAC to MP3
- Add your FLAC filesDrag an album folder or single files onto WAVR, or click Browse files.
- Choose a bitrateMP3 is selected at 320k. Lower it to fit more music on a device.
- Convert and downloadClick Convert all, then Download all to save the album.
Recommended settings
- DJ USB or club play: 320k, sample rate Keep. Leave Normalize off so the mastered levels stay as released.
- Phone or car: 256k or 192k. Hard to tell apart from 320k on earbuds or in a car.
- Hi-res FLAC (24-bit / 96 kHz): set the sample rate to 44.1 or 48. WAVR does this automatically for MP3 anyway.
FLAC to MP3 questions
Do FLAC tags carry over to the MP3?
WAVR reads the title, artist, album, year, BPM and genre from the FLAC file's Vorbis comments and passes them to the MP3 encoder.
What about 24-bit or 96 kHz FLAC?
High-resolution FLAC converts fine. MP3 supports up to 48 kHz, so WAVR resamples 88.2 and 96 kHz files to 44.1 or 48 kHz before encoding.
Should I keep the FLAC files?
Yes, if you have the space. FLAC is lossless, so it's the best source for future conversions. Make MP3s for portable devices and keep the FLACs as your master copies.
Are my files uploaded?
No. WAVR decodes the FLAC and encodes the MP3 inside your browser, so nothing is sent to a server.
