How do I crop a PDF?
Open your file, then tell the tool how much to take off the top, bottom, left and right. The preview shows the page with the area that will remain, so you can nudge the numbers until nothing important is cut. Choose whether the crop applies to all pages or to a page range, then save the new copy.
The content you keep is not rebuilt or turned into a picture. Text stays selectable and images keep their original quality. It is a quick way to fix a scan before attaching it to an email or a tax form.
Tip: Check the preview on the page with content closest to the edge. A crop that suits page 1 can clip a table on page 7.
How do I remove white margins from a PDF?
Wide margins come from all sorts of places. A scanner adds a dark border or a strip of desk around the sheet. A report exported from a spreadsheet leaves a band of white on one side. Slides have generous margins that waste paper and make text tiny on a phone. Trimming that dead space makes the part you care about bigger.
- Crop to a range when the document is mixed. If only the scanned pages have borders, trim those and leave the typed pages alone.
- Rotate first if a scan is sideways. Fix orientation before trimming, so the sides you set match the sides you see.
- Leave a little breathing room. Cutting exactly to the text looks cramped, and printers may clip the very edge of a sheet.
- Keep the original. Save the cropped version under a new name so you can always go back to the full page.
Does cropping a PDF delete the hidden content?
No, and this matters if you are cropping to hide something. Cropping tells PDF readers which part of the page to show. Whatever sits outside the crop is hidden from view, but it is still inside the file, and someone with the right software could reveal it again.
So crop for looks, not for secrecy. If you need to remove a name, an account number or a signature for good, use a redaction tool, which deletes the content underneath instead of covering it.
Is it safe to crop a PDF online?
Yes, here it is, because the PDF never leaves your device. Many online editors upload your file and crop it on their server. This page runs the cropping inside your browser instead, on Windows, Mac, Linux, Android or iPhone. Nothing is transferred, so there is no upload to wait for and large files are limited only by your own hardware.
You can confirm this yourself: watch your browser’s network tab while you crop and save, and you will see that your documents stay with you.
