About this tool
Handy for cutting dark scanner edges or extra white space. The area you pick on page 1 is applied, as the same share of the page, to every page.
When to use it
Crop a PDF to remove scanner borders, black edges and unwanted margins, or to focus on a table or figure. Draw a box on the page or let the tool trim the white edges automatically.
Tips
Apply the same crop to all, odd or even pages when a scanned book has a shifting gutter. Check the first and last pages before downloading, because the content position can change between pages.
Privacy
Everything runs in your browser, so your data is not uploaded or stored.

常見問題
Can the cropped part be restored?
No, it is no longer visible in the result. Your original file stays with you.
What if pages have different sizes?
The same percentages are used on every page, so mixed sizes still work.
Does cropping delete the hidden content?
Cropping hides the outside area on the page view. For permanent removal of private data use the Redact PDF tool.
Can I crop odd and even pages differently?
Yes. Apply a crop to odd pages and another to even pages.
