How to convert FLAC to OGG
Add your FLAC files
Drag and drop FLAC files into the box or tap to choose them. The converter engine (about 31 MB) downloads once, the first time you convert.
Pick a bitrate
192 kbps suits music and 128 kbps or less suits speech. Sample rate and mono/stereo are under Advanced.
Convert and download
Click Convert, then download each OGG file or all of them as one ZIP.
Why convert FLAC to OGG?
OGG is a natural, royalty-free lossy companion to FLAC for games and Linux players.
What happens when you convert FLAC to OGG?
The FLAC is encoded to Vorbis at 192 kbps.
How does Fylo convert FLAC to OGG?
Fylo decodes the FLAC audio in the FLAC with ffmpeg compiled to WebAssembly and encodes it with the Vorbis encoder (libvorbis) at 192 kbps in an Ogg container. Going from lossless to lossy is where the big saving happens: a 3-minute song is ≈ 18–24 MB as FLAC but ≈ 3.6 MB at 160 kbps as OGG. The original sample rate and channel layout are kept unless you change them under Advanced.
What's the difference between FLAC and OGG?
FLAC (Free Lossless Audio Codec) was released in 2001 and later maintained by the Xiph.Org Foundation. It compresses PCM audio like a ZIP file compresses data: nothing is thrown away, so a FLAC decodes to exactly the same samples as the source WAV, typically at 50–70% of the size.
Ogg is an open container from the Xiph.Org Foundation; Vorbis, the audio codec most .ogg files use, reached version 1.0 in 2002. Vorbis was created as a free, unpatented alternative to MP3 and sounds better at the same bitrate.
