Convert FLAC to MP3
FLAC is lossless and ideal for archiving, but the files are large and some players won't open them. Keep your archive as it is and make MP3 copies for listening on the go.

Common issues with FLAC files
- 24-bit / 96 kHz FLAC: The tool reads it; since MP3 carries at most 48 kHz, the sample rate is lowered.
- Album art and tags: Not carried over to the output.
- Quality: Choose 256 or 320 kbps for music.
Privacy: your file never leaves your device
Everything happens in your browser. Your file is not sent to Voiser's servers or stored anywhere, and it's cleared from memory when you close the tab. That's also why the tool stays fast on a slow connection.
Common questions
What do I lose going from FLAC to MP3?
Because MP3 is lossy, the details the ear notices least are discarded. At 320 kbps the difference is subtle in most listening conditions; keep the original as FLAC.
Can I convert a whole album at once?
You can add up to 10 files at a time; for more, repeat in batches.
Is there a way to stay lossless instead of MP3?
Yes: choose WAV in the audio converter. The file gets bigger but the quality doesn't change.
Is my file uploaded to a server?
No. Your FLAC file is converted in your browser; it isn't sent to Voiser or anywhere else, and it isn't stored.
