About FLAC to MP3 conversion
FLAC is what you get from Bandcamp downloads, careful CD rips and hi-res music stores: bit-perfect audio at roughly five times the size of an MP3. That is exactly what you want in an archive and exactly what you do not want on a phone with 30GB free, in a car stereo, or on a old MP3 player — most of which cannot open a .flac file at all.
Converting to 192kbps MP3 makes the library portable while keeping the FLAC originals untouched as your master copies. Whole albums convert in one go on your own device, with no upload and no per-file limit.
Frequently asked questions
Roughly 4–5× smaller. A typical album of FLAC files runs 250–400MB; the same album as 192kbps MP3 lands around 60–80MB. The exact ratio depends on the music — dense material compresses less well as FLAC, so it shrinks more when converted.
Yes, in the technical sense — FLAC is lossless and MP3 is not. In normal listening at 192kbps the difference is inaudible to almost everyone on almost all equipment. Keep the FLAC files as your archive and treat the MP3s as the portable copy.
Yes — drop in as many FLAC files as you like and they convert one after another in your browser, then download together as a single ZIP. Because nothing is uploaded there is no size limit to worry about.
No. The conversion runs entirely in your browser using WebAssembly (FFmpeg). Your recording never leaves your device — that is also why there is no upload wait, no queue and no file-size pricing. For personal recordings, lectures and meetings this matters more than anywhere else.
Up to 8GB on desktop browsers and 2GB on mobile — big enough to pull the audio out of a multi-hour lecture or meeting recording. There is no limit on the number of files, no signup and no watermark.
192kbps, which is transparent for speech and very close to transparent for music. The audio stream is decoded once and encoded once — there is no extra generation loss from server-side re-processing.
Yes — completely free and unlimited, with no watermark, signup or daily quota. Because the conversion runs on your own device instead of our servers, there are no processing costs to charge for.
Yes. It runs in any modern browser — Chrome, Safari, Edge or Firefox — on Windows, macOS, ChromeOS, Linux, iOS and Android. There is nothing to install.
Audio-only work is fast: there is no video to re-encode, so even the soundtrack of a long video converts in well under real time. Files whose audio is already MP3 are rewrapped without re-encoding and finish in seconds.
