Convert FLAC to OGG — Free & Private
FLAC from Bandcamp, HDtracks, vinyl rips, and archival recordings is ideal source material for OGG conversion. Encoding from lossless gives you the cleanest possible OGG — no generation loss from a prior lossy encode.
FLAC as Source: The Cleanest Path to OGG
When you need OGG files for a game, web project, or Linux application, the source format you encode from matters enormously. MP3 has already discarded audio data through its lossy compression — when you re-encode that degraded signal to OGG, the encoder works with incomplete frequency information. FLAC is different. FLAC is lossless: every sample from the original recording is intact, perfectly preserved since the moment it was mastered. Converting FLAC to OGG means the OGG encoder has the full, uncompromised audio to work with. The result is the best OGG quality you can get — equivalent to encoding directly from the recording studio master. This matters in practice for game developers who receive FLAC stems from composers: converting those stems directly to OGG (rather than exporting to MP3 first) produces noticeably better audio quality at the same file size. Bandcamp download users who purchased FLAC can convert to OGG for Godot or Unity game projects, or for playing in Linux media players, while retaining the full fidelity of their purchased music.

Why FLAC Is the Best OGG Source
- 🎯 Lossless source = best possible OGG quality — no generation loss from a prior lossy encode
- 🎵 Bandcamp FLAC downloads → Unity/Godot game audio in one step
- 📦 85–90% smaller than FLAC — OGG at 192kbps vs lossless FLAC
- 🎮 OGG streams efficiently in Godot 4 — directly from disk for long background tracks
- 🆓 Royalty-free output — OGG Vorbis is patent-free for commercial game projects
- 🔒 100% private — your FLAC files never leave your browser
FLAC to OGG Quality Guide
Quality 6–7
≈192–224kbps. Recommended for music from Bandcamp. Captures full FLAC detail at 10% the file size.
Quality 4–5
≈128–160kbps. Ideal for game background music. Good quality, smaller build size.
Quality 2–3
≈80–112kbps. Voice and sound effects. Significantly smaller files for mobile game assets.
Lossless Source
Any quality setting produces better results from FLAC than from an MP3 source at the same target bitrate.
Streaming
192kbps OGG from FLAC is transparent to most listeners — indistinguishable from the source on typical headphones.
Privacy
All conversion runs in your browser via FFmpeg.wasm. No server, no upload, no account required.

How does FLAC to OGG compare to other lossy conversions?
Converting from FLAC gives the Vorbis encoder the cleanest possible input — there's no earlier lossy compression for it to compound. Ogg Vorbis is generally considered slightly more efficient than MP3 at the same bitrate, meaning a Vorbis file from FLAC at a given quality setting often sounds a touch better than an MP3 at the equivalent bitrate. At quality 8–10 (roughly 256–320kbps), the output is effectively indistinguishable from the FLAC for nearly everyone.
- Vorbis from FLAC starts from a clean, uncompromised source
- Quality 8–10 (~256–320kbps): essentially indistinguishable from the FLAC
- Vorbis is generally a bit more efficient than MP3 at matched bitrates
- Lower quality settings (2–5) trade detail for much smaller files — fine for games and voice
What OGG quality setting should I use for music vs. game audio?
For music you want to actually listen to, quality 6–7 (roughly 192–224kbps) keeps it close to the FLAC while cutting file size dramatically. For background music and ambient loops inside a game, quality 4–5 (roughly 128–160kbps) is usually plenty since players are focused on gameplay rather than critical listening. For voice lines, dialogue, and short sound effects, quality 2–3 (roughly 80–112kbps) keeps build sizes down without hurting clarity.
- Music for listening: quality 6–7 (~192–224kbps)
- Game background music and ambience: quality 4–5 (~128–160kbps)
- Voice lines and sound effects: quality 2–3 (~80–112kbps)
- Starting from FLAC means every setting performs at its best — no compounded loss
Why would a project need OGG instead of the FLAC directly?
File size and engine support. A FLAC library can be 5–10x larger than the same content as OGG, which matters for game downloads, web page load times, and mobile app sizes. On top of that, engines like Godot and Unity, as well as many HTML5 and JS audio libraries, are built around compressed streaming formats like OGG for music and longer audio, reserving uncompressed formats for very short, latency-critical sound effects.
- OGG files are typically 5–10x smaller than the equivalent FLAC
- Godot and Unity both have built-in OGG/Vorbis decoders
- Smaller OGG files mean faster downloads and smaller app or game builds
- Reserve FLAC/WAV for very short sound effects where instant playback matters
Is OGG a safe long-term format, or should I keep the FLAC too?
Keep the FLAC if it's your only copy of something you care about. Ogg Vorbis is open, well-supported, and not going anywhere, but it's still a lossy format — converting from FLAC discards data permanently, the same as converting to MP3 or AAC would. For game and app assets that's fine because the FLAC was just a working file. For music libraries, treat the OGG as a distribution copy and the FLAC as the master.
- Ogg Vorbis is open-source, royalty-free, and widely supported — a safe lossy format
- But it's still lossy: FLAC to OGG cannot be reversed without quality loss
- Game and app assets: the FLAC was likely just a working file, fine to discard after conversion
- Personal music libraries: keep FLAC masters, use OGG as a space-saving copy
