What if pages have different sizes?

The ratio set on the preview (first page) is applied to every page — differently-sized pages are cropped by that same ratio.

How to crop PDF

Select the PDF file to see a preview of the first page.
Drag to draw the area to keep, or adjust it with the corner handles.
Press Crop to This Area and the same ratio is applied to every page and saved.

💡 Trimming margins and unwanted areas

Whether a scan has wide margins or captures parts you don't want, selecting just the area to keep makes a document look much cleaner.

✏️ Drag to select: Draw the area to keep on the preview, or fine-tune it with the corner handles.
📐 Applies to every page: The ratio you set is applied identically to all pages, even ones with different sizes.
🔒 Browser-only processing: Files are never sent to a server — processing happens only in your browser.

📌 Where is cropping a PDF useful?

Trimming scan margins — cut away the extra white space a scanner leaves around the page.
Matching a social/thumbnail ratio — crop pages to 1:1, 16:9 or another ratio you need.
Keeping only part of a page — extract just a table or figure and drop the rest.
Matching print trim lines — adjust margins to spec before sending to a printer.

✨ How to crop the exact area you want

Drag over the preview to mark the area to keep, then fine-tune it with the corner handles.
The ratio you set on the first page is applied to every page the same way.
Pages of different sizes are still cropped to match that same ratio.

🔒 Is the cropped-out area gone for good?

Yes. Cropping permanently removes everything outside the selected area when it saves. If you want to keep the original, make a copy of the file before cropping.
