Convert OGG to FLAC
Convert an OGG file to FLAC, a compressed lossless container with room for full tags and cover art. It runs in your browser, so the file never leaves your device.
Why convert OGG to FLAC?
People convert OGG to FLAC when they want a tidy, well-tagged file for a hi-fi music library or a long-term archive. FLAC is the darling of archivists and audiophile players because it packs in rich metadata and cover art while staying lossless, and tools like foobar2000, Plex, and most modern music servers handle it natively. If you are consolidating a collection and prefer everything in one archival container, FLAC is a common target. Just note that some car stereos and parts of Apple software still lack native FLAC playback, so check your player first.
Quality and file size
FLAC is lossless, but converting from OGG does not add quality back: OGG already discarded data during its lossy encode, and FLAC simply preserves whatever it is given. So the FLAC holds the exact same audio as the OGG, no better and no worse. The upside is size and organization: FLAC compresses to roughly 50 to 60 percent of an equivalent WAV while staying bit-for-bit identical to that PCM, and it carries proper tags and artwork. Treat this as archiving and tagging your OGG audio in a lossless wrapper, not as an enhancement.
OGG to FLAC: common questions
Does converting to FLAC make the audio higher quality?
No. OGG is lossy, so the detail it dropped is gone for good, and FLAC only preserves the audio it receives. You get the same sound in a lossless, well-tagged container, not an upgrade.
How big will the FLAC be?
FLAC is lossless but compressed, typically 50 to 60 percent of the size of an uncompressed WAV of the same audio. It will usually be larger than the original OGG, since OGG is lossy.
Is my file uploaded to a server?
No. The conversion runs in your browser with FFmpeg compiled to WebAssembly. Your OGG never leaves your device, and we never see it, store it, or train on it.
Will FLAC play everywhere?
It is widely supported now on players like foobar2000, VLC, and Plex, but some older or car devices and some Apple software still lack native FLAC playback. Check your target device before committing a whole library.
