# PDF Crop

Trim the margins of PDF pages by setting how much to cut from the top, right, bottom and left in millimeters or points. The tool changes the crop box of each page, the visible area that viewers and printers use, so content outside it is hidden but not deleted and can be restored. Crop every page or a range, for example to remove white borders, scanner edges or printer marks.

## Frequently asked questions

### How does cropping work?

Every PDF page has a crop box that defines the area shown and printed. The tool moves the edges of that box inward by the amounts you enter, starting from the current crop box. The page content itself is not changed, so the cropped areas stay in the file.

### Is the cropped content really removed?

No. It is hidden, not deleted, and anyone with a PDF editor can restore the full page by resetting the crop box. Do not use cropping to remove confidential content; redact or delete it instead.

### Which units can I use?

Millimeters or points, where 72 points make an inch and one millimeter is about 2.83 points. Each margin can be from 0 to 5000 of the chosen unit, and decimals such as 12.5 are allowed.

### Do the margins follow rotated pages?

Yes. Top, right, bottom and left refer to the page as you see it in a viewer. For a page stored with a 90 degree rotation, the tool maps each margin to the matching side of the stored page.

### What if I cut too much?

The visible area must stay at least 18 points, about 6 millimeters, wide and high. If the margins would leave less on any selected page, nothing is saved and the message names that page.

### Can I crop only some pages?

Yes. Enter pages such as 1, 3-5 or 10- in the pages field to crop just those, and leave it empty to crop every page. Pages of different sizes are cropped by the same margins.

### Does cropping reduce the file size?

No, because the content outside the crop box stays in the file. To shrink a document, run a compression tool afterwards or delete the pages you do not need.

### Does it change the page size for printing?

Most viewers and printers use the crop box as the page size, so a cropped page prints smaller or is scaled to the paper. The media box, which describes the original sheet, is left as it is.

### Can I crop a password protected PDF?

Yes. Enter the password in the password field. The cropped file is saved without password protection, and the password is not returned.

### What are the limits?

PDFs up to 10 MiB and 200 pages and up to 30 seconds of processing. At least one margin must be greater than zero, and annotations, links and form fields are kept in place.
