Converting FLAC to MP3 compresses a lossless archive down to a portable, universally compatible format. The audio is bit-perfect PCM going in, so you get the best possible MP3 output for a given bitrate: no transcoding artifacts on top of the encoder's own lossy decisions.

MP3 is lossy; FLAC is not. You'll lose some detail, but since you're starting from a lossless source the encoder has clean input to work from. At 192 kbps most listeners can't distinguish the MP3 from the FLAC on consumer gear; at 320 kbps even careful listeners struggle.
MP3 plays on literally every audio device made in the last 25 years. You will never encounter a playback environment where MP3 doesn't work.
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.
MP3 is the most widely supported lossy audio format. Encoded in 1993 and still the default on countless devices, it trades some fidelity for dramatically smaller files. At 192 kbps most listeners cannot distinguish it from the source. Anything that plays audio will play MP3.
320 kbps if you want to minimize audible difference. 192 kbps VBR is transparent to the vast majority of listeners. Below 128 kbps the loss becomes obvious on careful listening.
No. FLAC is your archival source. Keep it so you can re-encode to newer codecs (Opus, AAC) in the future without cascading quality loss from re-encoding MP3s.

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.
