Crop PDF margins and unwanted page borders
Set the crop on a content-heavy page first, then check pages from the beginning, middle, and end of the document. Keep the original file so you can try a less aggressive crop later.
How it works
Open the PDF and choose a representative page.
Drag the crop bounds around the area you want to keep.
Preview other pages, then apply and export a reading copy.
Questions people ask
Does cropping delete the hidden content?
The standard PDF crop setting changes the visible area rather than necessarily removing the underlying content. Keep the original file in case you want to change the crop later.
Will a cropped PDF print correctly?
Most current viewers respect the crop setting. Always inspect the print preview, especially if you are using an older print kiosk or shop workflow.
Why crop a PDF for a Kindle or tablet?
Removing empty margins lets the reader devote more of the screen to the actual text, which can make a fixed-layout PDF easier to read.
Does my PDF get uploaded?
No. The tool reads and edits the file in your browser. Exported files are downloaded directly to your device.
Should I keep the original file?
Yes. Exported files are new copies, but keeping the original lets you revisit a different edit or recover from a mistake.
