FLAC is for the archive; MP3 is for the pocket

FLAC stores music losslessly — every bit of the CD or studio master — and a typical album lands between 300 and 500 MB. That is ideal on a home server and a burden everywhere else: many phones and car systems still refuse the format, streaming it over mobile data is wasteful, and a large collection fills a device fast. "Convert flac to mp3" is the search people make when their carefully ripped library has to travel.

The MP3 copy is a delivery format, not a replacement. Convert for the phone, the car USB stick, the old player, the shared playlist; keep the FLAC as the master you can always convert again later. The reverse is not true — an MP3 turned back into FLAC is just a large MP3.

192 kbps MP3 or WAV: what you get

The MP3 is encoded at a constant 192 kbps. On a CD-quality FLAC that cuts the size by roughly two thirds while keeping the sound transparent for the overwhelming majority of listeners and headphones. A 35 MB FLAC track becomes about 6 MB; a full album fits in around 80 MB. Sample rate and stereo channels are preserved from the source.

Choose WAV instead when the target is an editor, a CD burner or a device that wants raw PCM. WAV is 16-bit uncompressed, so nothing is lost after decoding — but it is as large as the FLAC or larger, so it is a format for working, not for carrying. High-resolution FLACs (24-bit, 96 kHz) decode fine and are written as standard 16-bit WAV.

• Phone, car, old MP3 player → MP3, about a third of the size
• Sharing an album with friends → MP3, plays on anything
• Editing, mastering, burning to CD → WAV
• Archive → keep the FLAC; do not overwrite it

Converting a whole library, and what happens to tags

The converter works one file at a time, which is exactly right for a handful of tracks and workable for an album — drop each file, download, next. For thousands of files a desktop batch tool is the better fit; for everything short of that, doing it here means no install, no plugin and no server involved.

The output file keeps the source's file name, so "03 - Track Title.flac" becomes "03 - Track Title.mp3" and albums stay in order in any folder view. Embedded album art and tags are not the focus of a conversion tool, so if your player relies on them heavily, run a tag editor over the MP3s afterwards.

Your music stays on your machine

Every step runs inside your browser, using the WebAssembly and Canvas APIs your device already ships with. No file is uploaded, no copy is kept, and nothing sits in a queue on a server waiting to be deleted — which is also why the tool keeps working with the network disconnected.

A FLAC library is often the result of years of ripping and buying, and uploading it track by track to a converter's server is both slow and pointless. Here the browser decodes the FLAC with its own audio engine and encodes the MP3 in JavaScript; a 35 MB track that would take a minute to upload starts converting the instant it is dropped, and never leaves the disk it lives on.

No account, no daily limit, no file-size tier: the resources being spent are your own CPU and memory, and the tool has no way to count how many tracks you convert.
