FLAC keeps every sample; MP3 plays everywhere. Turn a lossless FLAC file into a compact MP3 right in your browser — the audio never leaves your device.
· The first conversion downloads the FFmpeg engine (about 32 MB). It is cached afterwards.
· Keep files under 2 GB, and under a few hundred MB if you are on a phone or re-encoding video.
· Keep this tab in the foreground — browsers throttle background tabs and the conversion will pause.
How to convert FLAC to MP3 in 3 steps
1
Add your FLAC file
Drop a .flac file onto the box above — a CD rip, a Bandcamp or HDtracks download, an archive export or a DAW bounce all work.
2
Pick the MP3 bitrate
320 kbps keeps as much as possible from the lossless source and is the default here. Use 192 kbps for everyday listening, or 128 kbps for spoken word.
3
Convert and download
Press Convert. The FFmpeg engine decodes the FLAC samples and encodes them to MP3 on your own CPU, then the download starts automatically.
About FLAC and MP3
What FLAC is, and why people keep files in it
FLAC — Free Lossless Audio Codec — compresses audio to roughly half the size of a WAV without discarding a single sample. Decode it and you get back exactly the bits that went in, which is why it is the default choice for CD rips, digital music stores such as Bandcamp, live-recording archives and anyone who backs up a music library properly. The catch is playback: outside dedicated music apps and modern hi-fi gear, FLAC support is patchy, and plenty of car stereos, Bluetooth speakers, DJ controllers and older phones simply will not open it.
Why convert a perfect file to a lossy one
Because the perfect file is useless in the places you actually listen. A FLAC that will not play in the car, cannot be sent over a messaging app and eats 30 MB per track is an archive format, not a listening format. MP3 remains the one codec every device, platform and music player handles without argument, and a 320 kbps MP3 made from a lossless source is transparent for almost every listener on almost every system. The sensible pattern is to keep the FLAC as the master and make MP3 the copy you carry around.
Getting the best result from a lossless source
A FLAC has never been through a lossy encoder, so this is the cleanest possible starting point: there is no compounding of earlier compression artefacts, unlike converting a downloaded M4A or an old MP3. That headroom is why 320 kbps is the default on this page — the source can actually justify it. Going above 320 kbps adds nothing but size, and choosing a lower bitrate throws away detail the FLAC was protecting. Text tags such as title, artist and album are carried into the MP3; embedded cover art is not, so re-add artwork with a tag editor afterwards if your library relies on it.
Frequently asked questions
How do I convert FLAC to MP3 for free?
Add the FLAC file to the drop zone at the top of this page, choose a bitrate and press Convert. It is completely free — no account, no watermark and no daily conversion limit.
Does converting FLAC to MP3 lose quality?
Yes, technically — MP3 is a lossy format. But because the source is lossless, a 320 kbps MP3 from a FLAC is transparent for virtually all listeners and equipment, with no artefacts inherited from earlier compression.
What bitrate should I choose?
320 kbps is the default and the right choice when the source is a lossless FLAC. Use 192 kbps if file size matters more than absolute fidelity, and 128 kbps for podcasts or voice recordings.
Are tags and album art preserved?
Text tags — title, artist, album, track number — are copied into the MP3. Embedded cover art is not carried over, so if your library depends on artwork, add it afterwards with any tag editor.
Can I convert FLAC to WAV instead, with no quality loss?
Yes — that is what our MP3 to WAV companion tool does for compressed files, and a FLAC to WAV conversion is completely lossless. But a WAV solves none of the compatibility problems MP3 does, and it is roughly twice the size of the FLAC.
Is there a size or length limit?
Files up to about 2 GB work, which covers full albums and long live recordings with room to spare. A typical three-minute FLAC track converts in a few seconds on a desktop once the engine is cached.
