OGG (Vorbis) is a free, open lossy format with very good quality per byte — a favourite in games, open-source software and projects that want to avoid patent-encumbered codecs.

FLAC compresses audio without losing anything — a perfect, bit-for-bit copy at a fraction of the WAV size, which makes it the default choice for archiving music.

Converting OGG to FLAC is about compatibility rather than quality: some editors, DAWs and pipelines simply insist on FLAC. You get a file they open natively — but the audio can never get better than the OGG you start from.

How the conversion works

  1. Choose your OGG file (up to 10 MiB). The button above opens the converter with FLAC already selected as the target format.
  2. There is no bitrate to choose: FLAC is lossless, so the bitrate field is simply ignored.
  3. Run the conversion and download the result — the output keeps your filename with a .flac extension. Everything happens locally: the page runs ffmpeg compiled to WebAssembly, so your audio is never uploaded to a server.

What to expect

No quality is restored. FLAC preserves exactly what's in your OGG file — detail the OGG encoder already discarded is gone for good. Expect a much larger file with identical sound; convert because a tool needs FLAC, not to upgrade the audio.

Embedded album art is dropped along the way: cover images ride along as a video stream, which audio-only outputs like FLAC can't carry.

FAQ

Does converting OGG to FLAC improve the audio quality?

No. FLAC preserves exactly what's in the source — detail the OGG encoder already discarded is gone for good. Convert because a tool needs FLAC, not to upgrade the sound.

Why is the FLAC file so much larger than my OGG?

OGG stores heavily compressed audio; FLAC stores a losslessly-compressed copy of the decoded audio — so the same sound takes several times the space. That's normal, and the extra bytes don't add quality.

Is my OGG file uploaded when converting to FLAC?

No. The page downloads an ffmpeg WebAssembly build once, then converts your file locally in the browser tab — the audio never leaves your device. Input files up to 10 MiB are supported.
