Convert FLAC to MP3
Turn lossless FLAC files into MP3s small enough for a phone and playable in any car. The FLAC is decoded on your own device and never uploaded.

How it works
Add your FLAC
Drop the file in. Its length, sample rate and channels are read straight away.
Choose the bitrate
320 kbps keeps as much as MP3 can hold, which is what most people want from a lossless source. 192 kbps halves the size for very little difference.
Download the MP3
One file, named after the FLAC, ready for a phone or a car.
Frequently asked questions
Which bitrate is right when the source is lossless?
320 kbps if space allows: you started with everything, so there is no earlier loss to compound, and this is the most MP3 can carry. 192 kbps is genuinely hard to tell apart on ordinary headphones and is little more than half the size. Below 160 kbps you are throwing away the reason you kept FLAC.
Am I losing my lossless files?
Only if you delete them. Keep the FLACs — they are your masters, and any future format can be made from them. The MP3s are copies for a phone or a car. Converting in this direction is one-way: an MP3 can never be turned back into the FLAC it came from.
How much smaller will it be?
Roughly a quarter to a third of the FLAC at 320 kbps, and about a sixth at 192 kbps. FLAC is already compressed — just losslessly — so the saving is smaller than converting from WAV.
Do the tags and artwork come across?
Not yet. The sound is converted; titles, artists and cover art are not carried over. If your library depends on tags, a desktop library manager is the better tool for a bulk conversion.
Is my file uploaded?
No. FLAC files are large and uploading a library would take hours; here everything is decoded and encoded by your own browser, so nothing is sent anywhere.
What about 24-bit or high sample rate FLACs?
They convert fine. MP3 stores 16-bit at up to 48 kHz, so a 24-bit 96 kHz FLAC is brought down to that on the way — which is what every portable player would do with it anyway.
Good to know: Tags and cover art are not carried across yet. MP3 holds at most two channels at up to 48 kHz, so multi-channel and high-rate FLACs are folded down.
