cutline.

The scan preparation workspace. A browser cropper for photos and PDFs. Local by design — processing stays on your device.

Demo

Drop scans on the landing page, or try a sample batch without bringing your own files.

Crop a single page, or split a spread into Crop A and Crop B
Drag a crop to move it, drag corners to resize, arrow keys for fine steps
Mark ready & next through the queue (Enter). J / K to navigate
Output presets: A4, US Letter, square — or custom pixels. Crop proportions stay locked
JPG or PNG, with a quality slider
Export reviewed pages as a ZIP, or save directly to a folder for large batches

Only pages you marked ready are exported. Originals are never changed. Close the tab and the session is gone.
