Guides for cropping PDFs
How to crop a PDF
- Open your PDF in the cropper.
- Drag the green box to move it, or drag a handle to resize it. Use the arrows or the page strip to check other pages.
- Choose Apply to: all pages, this page only, odd pages or even pages.
- Click Crop PDF. The file is named …-cropped.pdf.
How to remove white margins automatically
- Click Auto-crop white margins.
- Raha looks at the pages you're cropping and sets the box around all the content, with a little breathing room.
- Adjust the box if needed, then save.
How to crop by an exact amount
- Pick mm or inch next to Margins to remove.
- Type the amount to remove from the top, bottom, left and right. The box moves to match.
- For example, enter 20 mm on the left to cut off a binding margin.
How to crop odd and even pages differently
- Set the crop for odd pages and choose Odd pages under Apply to, then save.
- Open the saved file, set the crop for even pages, choose Even pages, and save again.
- This is the easiest way to trim the inner margins of a scanned book.

FAQ
Crop PDF questions, answered
How do I crop a PDF?
Open the PDF, drag the crop box (or type margins, or use auto-crop), choose which pages to apply it to, then click Crop PDF.
Can I crop white margins automatically?
Yes. Click Auto-crop white margins and Raha sets the box around the content on your pages.
Can I crop by an exact amount?
Yes. Type the margins to remove from each edge in millimetres or inches.
Can I crop only one page?
Yes. Choose This page only under Apply to. You can also crop odd or even pages.
Is the cropped content deleted?
It's hidden, not deleted. The crop sets the visible area of each page, which is how PDF cropping works in Acrobat too. To permanently remove sensitive content, use Redact PDF.
Are my files uploaded?
No. Cropping runs in your web browser, and your PDF never leaves your device.
Is Crop PDF free?
Yes. The free plan needs no account and adds no watermark. It includes 3 tasks per hour, with files up to 50 MB and 200 pages. The Pro plan removes the limits.
