Trellis quantisation and progressive scans. Usually 30–70% smaller than camera or Photoshop output.
A dithered palette, then a tighter compressed stream. Switches to lossless when a palette would show.
-O3 with lossy LZW. Every frame and the animation timing are kept.
Photos inside the PDF are resampled and re-encoded, loose streams are deflated, and objects are packed. Text and vector graphics stay sharp.
Uses your device's hardware video encoder, so it's fast. Output is MP4, which plays everywhere. Bitrate never exceeds 75% of the original.
Drop whole folders. Files run in parallel on background threads, and the ZIP keeps your folder structure.
Pick "Smallest of all formats" and each image keeps whichever format wins.
