Clop is an image, video, PDF and clipboard optimiser for macOS. Copy large, paste small, send fast. While Clop runs, every image you copy is optimised to the smallest possible size with minimal to zero loss in quality, ready to paste in any app.
It shrinks screen recordings as small as screenshots, converts to modern formats like JPEG XL and AV1, downscales and crops images and videos with hotkeys, optimises files by drag and drop or Preset Zones, and compresses PDFs to fit under email limits. Everything happens on-device, with no cloud services.

The name
Clop is the Romanian word for a traditional straw hat with a high crown and raised conical brim, worn as an adornment on days of celebration.
We thought "Clipboard Optimizer" sounded a bit too technical and didn't roll off the tongue. We're Romanian ourselves, so we kept a little piece of our traditions alive in the name.
