When to crop PDF pages
Scans with oversized borders, slides exported with letterboxing, printouts with scanner edges — cropping tightens all of them. A trimmed page also prints larger content on the same paper.
Cropping runs entirely on your device, so private documents stay private.

Frequently asked questions
Does cropping delete the content outside the box?
Cropping sets the visible page area — the standard, lossless way to trim PDFs. Some advanced editors can still see the underlying layer, so don't rely on cropping alone to redact secrets; use a dedicated redaction tool for that.
Can I crop just some pages?
Yes. Apply the crop to all pages or type a range like 1-5 when only a section needs trimming.
Which units can I use?
Millimeters and inches. Values are exact, so the same crop applies uniformly across pages.
Will cropping make my file smaller?
Slightly at most — the page definition shrinks, but the underlying content is preserved. Cropping is about layout, not compression.
Can I undo a crop later?
Your original file stays untouched on your device, so you can always start over from it.
Is cropping uploaded to a server?
No. The crop is computed and written locally in your browser.
