Should you convert OGG to FLAC?
A tool wants FLAC input from Ogg audio.
Only when software insists on FLAC. It stores the decoded OGG perfectly, but the detail the OGG discarded is already gone, so the FLAC is bigger without sounding better.
FLAC also plays in more places: most modern players, Android and recent iPhones; some car stereos and older apps don’t.
OGG is open-source lossy audio, common in games and on Android; FLAC is lossless audio at roughly half the size of WAV. Use FLAC to archive music and recordings you may want to convert again later.

What changes when OGG becomes FLAC
Bigger, not better
FLAC can’t restore what OGG compression removed. It does make editing easier and stops further loss, which is why editors and some broadcast systems ask for it.
Expect a much larger file
FLAC is far bigger for the same content. Choose it because something needs FLAC, not to send or store the file. OGG: Similar to or slightly smaller than MP3. FLAC: About 5–7 MB a minute for music.
This page is put together from our notes on each format, choosing only what is true of OGG and FLAC, so every pairing states the same facts the same way. How these pages are made.
Why it doesn’t upload
Recordings are often private: interviews, voice notes, unreleased music. Your browser can decode and encode audio itself, so there is no reason to send it anywhere.
How to check for yourselfWorth knowing
- About the OGG. The .ogg extension can hold Vorbis, Opus or FLAC audio, so one OGG plays in a player and the next doesn’t.
- About the FLAC. FLAC made from an MP3 is lossless only in name: it perfectly preserves an already lossy recording, at five times the size.
- MP3, WAV, M4A, OGG, Opus and FLAC are converted by your browser directly. WMA, AMR, APE, AC3 and the other specialist formats use the FFmpeg engine, a one-time 31 MB download.
