Convert FLAC to OGG
Last updated: June 1, 2026To convert FLAC to OGG, drop your FLAC file into the converter above, then download the OGG result. It's free, needs no sign-up, and there's no watermark. Conversion runs in your browser with on-device FFmpeg, so your files never leave your device.
Why convert FLAC to OGG?
Convert FLAC to OGG right here in your browser — no upload, no sign-up, no watermark. Your lossless FLAC files are re-encoded to OGG Vorbis entirely on your own device using FFmpeg compiled to WebAssembly, so the audio never touches a server or leaves your computer. The result is a much smaller, royalty-free file that still sounds excellent: a 25 MB FLAC track typically shrinks to around 5-6 MB of Vorbis audio, perfect for phones, game engines, and streaming.
- Freeing up phone or SD-card space: your music library is ripped to lossless FLAC for archiving, but you want a copy that's roughly a quarter of the size to sync to a phone or DAP without losing audible quality.
- Game and web development: Unity, Godot, the Web Audio API and HTML5 <audio> all favour OGG Vorbis for sound effects and music, so you convert FLAC source files into the royalty-free format the engine expects.
- Loading FLAC into apps that reject it: an older car stereo, a Vorbis-only media player, or a tool that won't read FLAC will happily play OGG, so converting gets your tracks working without buying new software.
FLAC vs OGG
FLAC · Free Lossless Audio Codec
FLAC is lossless but compressed — bit-perfect quality at roughly half the size of WAV. It's the audiophile and archival favourite, supported by most modern players.
OGG · Ogg Vorbis
OGG (Vorbis) is a free, open, lossy format with strong quality-per-byte. It's common in games and open-source software, but consumer hardware support is patchier than MP3.
FLAC to OGG — frequently asked questions
Will I lose audio quality converting FLAC to OGG?
Some, because OGG Vorbis is lossy while FLAC is lossless — but at the default quality level (around 192 kbps) most listeners can't tell the re-encoded file from the original in a blind test, and higher Vorbis settings get even closer to transparent. If you need a bit-perfect archive, keep your FLAC; convert to OGG when you want a smaller, more portable copy.
How much smaller will the OGG file be?
Usually dramatically smaller. FLAC stores CD-quality audio at roughly 20-25 MB for a 4-minute song, whereas OGG Vorbis at ~192 kbps lands around 5-6 MB — close to a 4:1 reduction. Across a few hundred tracks that adds up to tens of gigabytes saved.
Is it really private if the conversion is free?
Yes. The entire FLAC-to-OGG conversion runs locally in your browser through FFmpeg WebAssembly — nothing is sent to or stored on any server. That's what lets us keep it free, sign-up-free and watermark-free without ever seeing your files.
How do I convert FLAC to OGG?

Is it safe to convert FLAC to OGG here?
