FLAC to MP3 Converter
Convert FLAC audio to MP3 online for free — keep your lossless masters, and make small MP3 copies that play everywhere. Choose the bitrate, convert in your browser, download.
Masters and copies: the two-format library
Serious music collections already live this way: FLAC as the archive — bit-perfect, future-proof, large — and MP3 as the travelling copy that every car stereo, cheap speaker and legacy player accepts without argument. The audio converter above makes the copies: decode the FLAC, encode MP3 at the bitrate you choose, all inside your browser so a private library is never uploaded to make a smaller version of itself.
Choosing a bitrate without the folklore
At 320 kbps, MP3 is transparent — indistinguishable from the source — for the overwhelming majority of listeners and material. At 192 kbps, critical listeners may catch cymbal smearing on good headphones; everyone else will not. Speech is far more forgiving: 96–128 kbps is plenty for interviews and audiobooks. When in doubt, convert one track at two bitrates and listen to the busiest thirty seconds. The sibling pages WAV to MP3 and M4A to MP3 cover the same decision for those sources.
Never convert the only copy
MP3 encoding throws information away by design. Convert from the FLAC, keep the FLAC. Storage is cheap; re-ripping a collection because the lossless masters were deleted is not.
Private by design
Your audio is converted on your device. No uploads, no accounts, no listening history — because there is no server in the loop at all.
Frequently asked questions
Why convert FLAC to MP3 at all?
Compatibility and size. FLAC is lossless but large, and some players, cars and older apps refuse it. MP3 plays literally everywhere and is roughly a quarter of the size at 320 kbps.
Which bitrate should I choose?
320 kbps is perceptually transparent for almost everyone and still small. 192 kbps suits speech and casual listening. Below 128 kbps, artefacts become audible on music — fine for voice notes only.
Does the conversion lose quality?
Yes — MP3 is lossy, so converting discards some audio detail permanently. That is why you convert a copy: keep the FLAC as your archive master and treat MP3s as the portable edition.
Will tags and track info carry over?
Basic metadata handling depends on the file; if ID3 tags matter to you, check the first converted file in your player and re-tag in your library manager if needed.
Are my audio files uploaded?
No. Decoding and encoding happen in your browser. Your music library never leaves your device.
