What does cropping a PDF do?
Cropping changes the visible page area of a PDF. Scanner borders, extra white space, desk background, receipt edges and wide margins are the usual targets. It does not rebuild the document from scratch.

Trim PDF Margins Without Rebuilding the Whole File
Crop PDF is for pages that have too much empty space around the content. That often happens with scanned paperwork, exported slides, receipts, forms, shipping labels, handouts and documents that were photographed on a desk. Set the top, right, bottom and left crop values, choose which pages should be affected and download a cleaner copy that is easier to read on screen or print.
When Cropping Helps
Cropping fits the case where the page content is already right but the visible area around it is not. You might have a scan with a dark edge, a page that includes scanner glass, a receipt with extra background or a report where the margins make the document feel awkward on mobile. Instead of recreating the file, you can trim the page box and keep the document moving.
Choosing Crop Values
The crop fields use PDF points. Start with small numbers when you only want to shave off a border. Larger values remove more from the visible page area. If the first output is too tight, go back and reduce the crop values. For uneven scans, try cropping one side at a time so the edge that needs attention is easier to spot.
Selected Pages
You can crop all pages, odd pages, even pages or a custom page range. That matters when a cover page should stay untouched but the scanned pages after it require cleanup. It also helps with mixed documents where only a few pages have wide borders.
Not a Redaction Tool
Cropping changes what most PDF readers show on the page, but it should not be used to hide sensitive information. If the goal is to cover private text, use Redact PDF and review the output before sharing. Crop PDF is best for layout cleanup, not privacy removal.

Frequently Asked Questions
Does cropping permanently delete page content?
Cropping usually changes what a PDF reader shows, but it should not be treated as a safe way to destroy hidden or sensitive content. Some PDF tools may still inspect page data outside the visible crop area. Use Crop PDF for layout cleanup, not privacy removal.
Can I crop only some pages?
Yes. You can crop all pages or choose selected pages depending on the document. This helps when a cover page should stay unchanged but scanned pages inside the file need their borders trimmed.
What units do the crop values use?
Crop values use PDF points. Start with small numbers if you only need to trim a border. If the result cuts too much, lower the value and run the crop again. Uneven scans often need different values on each side.
Can I use Crop PDF to hide private information?
No. If the goal is to hide names, account numbers or other sensitive details, use Redact PDF instead. Cropping is for page margins and visible layout. Redaction is the safer workflow for covering information before sharing a file.
Why does a cropped PDF still show the old content in some tools?
Some PDF editors can show content that sits outside the cropped view because the page data may still exist in the file. That is normal for many PDF crop workflows. If you need the outside area removed for privacy reasons, do not rely on cropping alone.
