Ogg Vorbis
The open alternative to MP3
OGG files usually contain Vorbis audio, a free and patent-free lossy codec. It is common in video games, on Android and in open-source software.
Free Lossless Audio Codec
Lossless compression for music lovers
FLAC compresses audio without discarding anything: once decoded, it is bit-for-bit identical to the original, yet takes roughly half the space of WAV.
Audio is converted by ffmpeg running inside your browser. Your files never reach a server.
Queue up to 50 files and download them one by one or together as a ZIP.
Set the bitrate, bit depth, sample rate and channels — or simply keep the sensible defaults.
Add your OGG files to the converter above. FLAC is already selected as the output, so conversion starts right away. When a file is ready, click Download, or use Download all to get a ZIP.
Nothing more is lost: FLAC stores the decoded OGG audio exactly. It cannot restore detail that the OGG compression already removed, though — the file gets bigger, not better. Convert to FLAC when software requires it or for editing.
16-bit keeps CD-quality sources exactly; use 24-bit for high-resolution recordings. FLAC is lossless at any setting, so there is no bitrate to choose.
No. The OGG to FLAC conversion runs entirely in your browser using ffmpeg compiled to WebAssembly. Your files are never sent to a server, so even private recordings stay on your device.
Yes. Add up to 50 files; they are converted one after another, and you can download each FLAC file separately or all of them together as a ZIP archive.
