Clop, from the Low Tech Guys, is a Mac optimiser with a simple idea: copy big, paste small. While it runs, every image you copy to the clipboard is compressed to the smallest sensible size before you paste it. Drop in videos, images, GIFs or PDFs and Clop optimises them, converts them to modern formats such as JPEG XL, AVIF and AV1, and can squeeze a file until it fits under a size limit you choose. All processing happens on your own Mac. Updated Aug 21, 2026.
