How It Works
Three steps. Drag, choose, download.
Upload your PDF
Drag and drop the file or browse from your device. Multi-page documents are supported up to 1 GB.
Draw the crop area
Drag the selection on the page preview. Lock to a preset ratio, type exact dimensions, or auto-detect margins — whichever is faster.
Choose pages & download
Pick 'Current page' or 'All pages', then download. The cropped PDF stays sharp and searchable — fonts and OCR text preserved.
Meet the editor
Everything you need to crop precisely — nothing you don't. Five parts work together to make any selection feel effortless.
- 1
Drag-and-drop selection
Pull the rectangle anywhere on the page. Eight handles let you resize from any side or corner with pixel-perfect control.
- 2
Live dimensions
See the exact width and height in millimeters as you drag. Lock to an aspect ratio when you need a clean 1:1, 16:9, or A4.
- 3
One page or all pages
Toggle between cropping just the page you're viewing or applying the same selection to every page in the document.
- 4
Aspect-ratio presets
Free-form, square, 4:3, 16:9, A4, or US Letter — pick a preset and the rectangle snaps to keep that ratio while you resize.
- 5
Auto-detect margins
Let the editor find the printable area for you. One click trims whitespace and hugs the content edges.
