Clop

Image, video, PDF and clipboard optimiser

Copy large, paste small, send fast

Optimise images as soon as you copy them

As long as the Clop app is running, every time you copy an image to your clipboard, Clop will optimise it to the smallest possible size.

The optimised image will have minimal to zero loss in quality, and will be ready to paste in any app.

Screen recordings as small as screenshots

Sending screen recordings becomes 10x faster with Clop. The app will optimise the video as soon as you stop recording.

The video will be available as a floating thumbnail, ready for you to drag and drop in any app.

Clop can use Apple Silicon’s dedicated Media Engine chip for battery-efficient video encoding without using the CPU.

Downscale in a pinch

Get images and videos ready for sharing by scaling them down to any resolution.

Use handy hotkeys or the floating buttons to downscale the image or video and get an even smaller file size.

• - downscales incrementally from 90% until 10% of the original resolution
• 1…9 are for downscaling to specific sizes

Power user features

1. On-demand optimisation

Press Ctrl-Shift-C to manually optimise the current clipboard.

The action works on images, video files, paths, URLs, even base64 encoded images.

For more aggressive optimisation, Ctrl-Shift-A is also available.

2. Compatible formats

Clop automatically converts less compatible formats like HEIC, tiff, mov to formats understood by most devices.

The conversion is fully configurable from the app settings.

Original files are kept in a backup folder which can be accessed from the app menu.

3. macOS Shortcuts

Integrate Clop optimisation in your workflows through native macOS Shortcuts.

• Downscale and optimise images that you email weekly
• Download optimised images directly into your slideshow
• …and so on

What’s up with the hat?

Clop is the Romanian word for a traditional straw hat with a high crown and raised conical brim, worn more as an adorment in days of celebration.

We thought “Clipboard Optimizer” sounds a bit too technical and doesn’t roll off the tongue as easily. We’re Romanian ourselves and we thought it might be a good idea to keep the memory of our traditions from dying completely, with whatever little we can do.
