Will quality be lost?

Yes — MP3 is lossy. At 256 kbps or higher the loss is generally inaudible. For listening to lossless masters keep FLAC.

Why convert FLAC to MP3?

For phones, car stereos, Bluetooth speakers, and older players that don't understand FLAC, plus to save space — MP3 files are usually 4–5× smaller.

Are my files uploaded?

No. ffmpeg.wasm decodes and re-encodes locally; nothing leaves your device.
