Converting FLAC to OGG Vorbis re-encodes a lossless archive into a smaller, royalty-free lossy format popular with Linux distros and game engines. Starting from lossless source means the encoder has clean input, so the output is as good as Vorbis gets at that bitrate.

Vorbis is lossy; the encoder discards psychoacoustically masked content. Quality is generally indistinguishable from the FLAC at quality level 6 or higher, and still very good at level 4. You can't recover detail from the OGG, so keep the FLAC as your source of truth.
OGG runs on Android, Linux, Windows with codecs, modern browsers, and game engines. iOS doesn't play Vorbis natively; use AAC if you're targeting Apple devices.
FLAC is a lossless compressor: it shrinks PCM audio to roughly 50–60% of its original size and decodes back to a bit-perfect copy. It supports tags, cue sheets, and up to 32-bit / 655 kHz, which makes it the de facto format for CD rips and audiophile music libraries.
OGG Vorbis is a royalty-free lossy codec developed by Xiph.Org. At comparable bitrates it sounds cleaner than MP3, especially at 96 kbps and below, and it's the audio format used by Spotify's streams, most modern games, and open-source projects that want to avoid patent encumbrances.
Quality 6 (around 192 kbps VBR) is transparent for most listeners on most program material. Quality 8 (around 256 kbps) is transparent to nearly everyone. You won't gain much perceived quality above that.
Generally yes, especially at lower bitrates. Vorbis is newer, handles voice and cymbals more cleanly, and doesn't carry MP3's patent history. MP3 wins only on universal device compatibility.

Yes. The converter runs entirely in your browser using FFmpeg compiled to WebAssembly. Your audio files are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Files over about 2 GB total can get slow or hit browser memory limits. Process in smaller batches if you run into issues.
