FLAC to MP3
Convert FLAC to MP3 online for free — turn lossless FLAC music into MP3 files at up to 320 kbps that play on every phone, car stereo and player, at a fraction of the size. Trim, fade and normalise if you like. Runs privately in your browser.
100% private — your audio is converted on your device, never uploaded. Conversion happens on your device; nothing is uploaded.
Your browser decodes the audio and an open-source MP3 encoder (LAME, via lamejs) converts it on your device — nothing is uploaded. Works with MP4, MOV, M4A, WebM, MKV, WAV, OGG and more; very long files need plenty of memory, so trim if your browser struggles.
How to convert FLAC to MP3
- Drop your FLAC file in the box.
- Choose the MP3 quality (320 kbps keeps the most detail).
- Optionally trim, fade or normalise.

What you can use it for
- Fit a lossless music library onto your phone
- Play FLAC albums in the car and on older players
- Share tracks with people whose apps don't support FLAC

Will I hear a difference?
At 256–320 kbps most listeners can't tell MP3 from FLAC. Keep your FLAC files as the lossless master copies.
How much smaller is MP3?
A 320 kbps MP3 is roughly a third of the size of the FLAC; 192 kbps is about a fifth.
Which quality should I choose?
192 kbps sounds excellent for music and keeps files small; 320 kbps is the highest MP3 quality. For podcasts and speech, 96–128 kbps in mono is plenty.
Can I convert just part of the file?
Yes — set a start and end time (minutes:seconds) before converting. Fade in and out smooths the cut edges.
Is there a file size limit?
There's no upload limit because nothing is uploaded, but the whole file is decoded in your browser's memory. Files up to a few hundred MB work well on most computers; for very long recordings, convert in parts.
Is my file uploaded?
No. Decoding and MP3 encoding both happen on your device.
