Clop

Clop is a macOS utility that sits in the background and automatically compresses images, videos, and PDFs the moment you copy them to your clipboard. It also handles screen recordings, shrinking file sizes significantly with minimal quality loss. The goal is simple: you copy a large file, and when you paste it, a much smaller version is ready to use. This happens locally on your Mac, so your data never leaves your computer.

The app works by monitoring your clipboard and applying efficient, open-source compression algorithms. It's not just a passive tool; you can drag files onto a drop zone for manual optimization, set up custom presets for specific tasks like converting to WebP or adding a watermark, and use hotkeys for quick actions. Clop integrates deeply with macOS, supporting Shortcuts for automation and working with apps like Dropshare for uploading or Yoink for temporary file storage.

Clop is for anyone who regularly shares visual content and is tired of large file sizes slowing things down. It's particularly useful for people who send many screenshots in emails or chat apps, create tutorials with images, post content to websites, or share screen recordings with colleagues. By making files smaller without a noticeable drop in quality, it speeds up workflows and avoids upload limits.
