About FLAC and OGG
FLAC is lossless compression for audio — bit-identical to the source at roughly half the size of WAV. It is the archival format of choice for music collections and masters.
OGG Vorbis is a free, open lossy codec that beats MP3 at equivalent bitrates. It is common in game audio and open-source software, and every modern browser plays it.
Converting FLAC to OGG is lossy. 192 kbps is transparent for most listeners on most material; pick 320 kbps for the ceiling, or drop lower when small files matter more than fidelity.
How the conversion works
This tool runs FFmpeg — the same engine behind most media software — compiled to WebAssembly, entirely in the browser. The file is read locally, converted locally and saved straight from memory; nothing is ever uploaded, which also means no queues and no server-side file size limits.
The converter itself is a one-time ~31 MB download on the first conversion, cached by the browser afterwards. Once it is loaded, everything works offline.
