**Quick answer:** To crop a PDF, choose it here and keep “Trim white margins” to cut each page down to its printed area, or choose “Margins I set” and enter how many millimetres to remove from each side. The preview shows page 1. Cropping changes the page size only, so text stays sharp and selectable.

## How to use it

1. Choose the PDF.
2. Keep “Trim white margins”, or choose “Margins I set” and enter the millimetres to cut from each side.
3. Check the preview of page 1 and pick all, odd or even pages.
4. Press Crop PDF and download the result.

## Automatic or exact

- **Trim white margins** looks at each page and keeps the area with anything printed on it, plus a small border you choose. Pages keep their own sizes, which suits scans that are not all the same.
- **Margins I set** cuts the same number of millimetres from every page: best for books and slides where the layout repeats. Use odd and even pages to handle left and right pages differently.

## Lossless: nothing is redrawn

Cropping here changes the visible area of each page (its page boxes); the text, images and vector graphics are not re-rendered, so quality and file size stay the same and text can still be selected and searched. The part outside the crop is hidden, not deleted: a PDF editor could show it again, so do not rely on cropping to remove private information.

## Good uses

- Scans with wide grey or black borders around the paper.
- A4 or Letter documents you want to read on a phone or e-reader without zooming.
- Removing printer's crop marks and bleed from print-ready files.
