FLAC to MP3 Converter
Convert lossless FLAC audio to small, universally-playable MP3, free and entirely in your browser.
What is FLAC?
FLAC (Free Lossless Audio Codec) preserves audio at full, lossless quality — bit-for-bit identical to the studio master — which is why it’s the format of choice for archival music collections and audiophile downloads. That fidelity comes at a cost: FLAC files run 2–4x larger than an equivalent MP3.
Why convert FLAC to MP3?
MP3 trades a small, generally inaudible amount of quality for a much smaller file and universal playback on phones, car stereos, and budget devices that don’t decode FLAC at all. Converting FLAC to MP3 is the standard move when you need a track to just play everywhere, not sit in an archive.
How to convert FLAC to MP3
- Drop your FLAC file. Drag and drop a FLAC file, or click to browse. First use loads the ffmpeg.wasm engine (~31 MB, cached in your browser after).
- Confirm output is MP3. This page pre-selects MP3 as the output format — change it in the format picker if you’d rather export something else.
- Set quality and convert. Pick a quality or bitrate preset, then click Convert. Processing runs locally on your device and typically finishes in well under a minute for short files.
- Download. Click Download to save your MP3 file. Nothing was ever uploaded to a server.
Your file never leaves your browser — conversion runs locally via ffmpeg.wasm, not on a server.
Use Cases
- Fit a FLAC music collection onto a phone or MP3 player with limited storage
- Make an archival FLAC track playable on a car stereo or older device
- Shrink FLAC files before uploading to a platform with size limits
