AIFF (Audio Interchange File Format) uses uncompressed lossless encoding and is best for Apple professional audio — Logic Pro, GarageBand, and macOS music production workflows. FLAC (Free Lossless Audio Codec) uses losslessly compressed encoding and excels at high-fidelity music archives and audiophile listening where quality matters more than file size. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Typically 50–60% — a 600 MB Logic bounce folder lands near 300 MB FLAC. Bit-identical audio, instant decoding everywhere.
Working sessions stay AIFF for DAW speed; archive finished bounces as FLAC. Two tiers: fast workspace, dense vault.
Core title/artist/album map to Vorbis comments; take notes and artwork verify after. Tag at archive time, not later.
