Some formats (like AVIF) can take longer but deliver better savings. • RAW/DNG/TIFF support is best-effort. These formats can differ a lot between camera brands and apps (bit depth, embedded previews, tiled TIFFs, vendor metadata). On some devices, certain files may fail to decode or may require more memory than your phone can safely allocate. • If a RAW/DNG/TIFF file fails, try: re-opening the file and retrying, switching compression mode, or exporting/converting it to JPG/PNG/HEIC first.
