About lossless limits: Shannon's theorem caps how much any file can shrink without losing information. Already-compressed formats (JPG, MP4, MP3, ZIP) are near that limit — expect 0–5% in lossless mode. Visually lossless mode re-encodes with modern codecs (JPEG XL, AV1, Opus) and can recover 30–70% on media files with imperceptible quality change.
