About this tool

Cropping sets the page’s crop and media boxes, so viewers and printers show only the area you keep. The content outside is hidden, not deleted, which keeps quality perfect.

Frequently asked questions

Is the cropped content deleted?

It is hidden outside the new page box. Someone with a PDF editor could restore it, so don’t rely on cropping to remove sensitive content.

Can I crop just one page?

Yes, type its number in the Pages box.

What units can I use?

Millimeters or percent of the page size.

Are my files uploaded to a server?

No. ConvertBrightly processes files with JavaScript inside your browser. Nothing is sent over the network, and the files disappear when you close the tab. You can even disconnect from the internet after the page loads.
