Frequently Asked Questions

How do I convert FLAC to MP3?

Drop the FLAC onto the converter, choose a bitrate — 320 kbps is the usual pick for a lossless source — and press Convert. Solmi decodes the FLAC and encodes an MP3 on your device, with nothing uploaded.

How much quality will I lose?

Less than in most conversions, because FLAC is lossless: the encoder is working from the full-quality original rather than from audio that was already compressed once. At 320 kbps the result is about as close to the source as MP3 can get, and most listeners cannot reliably tell them apart.

How much smaller is the MP3?

Typically a third to a fifth of the FLAC. A 30 MB FLAC of a four-minute track lands near 9 MB at 320 kbps and near 5 MB at 192 kbps, which is what makes it practical for phones and USB sticks.

Should I keep my FLAC files?

Yes, if you have room. FLAC is your archival copy — you can always make another MP3 from it, but you can never rebuild a FLAC from an MP3. Treat the MP3 as a portable copy rather than a replacement.

Are my files uploaded anywhere?

No. The converter runs entirely in your browser: your file is decoded and re-encoded on your own device, and nothing is sent to a server. That is also why it is fast — there is no upload wait and no download wait, just the conversion itself.

Is the converter free?

Yes, completely free with no signup, no file-size paywall, and no watermark. Once your audio is converted, you can turn the track into a music video with Solmi's AI music video generator — also free to start.
