FLAC or OGG · as many as you like
- Takes
- FLAC and OGG files. Drop a whole album and they’ll convert one after another. Safari can’t open some FLAC files — if that happens, try Chrome or Firefox.
- Size
- No limit. A 50 MB, 12-minute FLAC took about six seconds here.

How to use it
Drop a FLAC file here and pick a quality: 320 kbps to keep it sounding great, or 192 kbps to save space. Your music stays on your device.
FLAC is perfect for keeping your music at full quality, but the files are big, and lots of phones, car stereos, and older players can’t play them. MP3 plays everywhere.
Drop your FLAC files onto the box above and pick a quality. At 320 kbps most people can’t tell the MP3 from the FLAC, and it’s about a fifth of the size. At 192 kbps you save even more, with a small difference you might hear on good headphones.
Because FLAC is perfect quality, this is the best possible starting point for an MP3 — as good as ripping the CD directly.
Keep your FLAC files — the MP3 is the copy for your devices, not a replacement.
FAQ
What quality should I pick?
320 kbps if it’s for listening, 192 kbps if you want to fit more on a device.
How much space will I save?
About five times smaller at 320 kbps and eight times at 192 kbps. A 25 MB FLAC song becomes about 7 MB.
Can I turn it back into FLAC later?
You can, but it won’t get the quality back. Keep your original FLAC files.
Are song details and album art kept?
Basic details usually are. Album art may not be, so tag the MP3 in your music app if needed.
Why did it stop with an error in Safari?
Safari can’t read some FLAC files. Your file is fine — try Chrome, Edge, or Firefox.
How it worksFor the curious
FLAC is lossless: it compresses audio to roughly half or two-thirds of the equivalent WAV and reconstructs the original samples exactly. Converting decodes back to those exact samples and encodes once with a lossy codec, so it is a first-generation encode with no compounding.
MP3 struggles most with cymbals and applause, which is where 192 kbps becomes audible on good equipment. The expected size is length × bitrate, shown before you start.
Basic tags are copied where the MP3 container can hold them; embedded artwork and unusual tag fields may not survive.
Safari’s FLAC decoder reports support but rejects some files. Chrome, Edge, and Firefox decode the same files without trouble, and the tool reports the decoder error rather than failing silently.
