FLAC to MP3 free — lossless to portable, no upload
FLAC is perfect for archiving and terrible for old car stereos, some Bluetooth speakers and cheap MP3 players. Converting to MP3 bridges the gap — but desktop converters want installing, and web ones want your music library uploaded.
ConvertFlow embeds FFmpeg (with LAME MP3 encoding) as WebAssembly. Drop your .flac files, convert, download. Batch works for whole albums.
Quality note: MP3 at LAME q4 (~165 kbps VBR) is transparent for most listeners and material; raise it via quality settings if your gear is fussy.
