About Crop PDF

Use Crop PDF when page edges contain excess margins or the visible page boundary needs to be tightened for reading or presentation.

What is Crop PDF?

Crop PDF changes the visible page boundary by applying trim margins. It is useful for wide scan borders, unused whitespace, or a cleaner presentation without rewriting the underlying page objects.

When this tool helps

  • Trim wide scan borders or unused margins.
  • Apply the same trim to a selected group of pages.
  • Prepare a cleaner visual page before converting or sharing it.

What happens to your file?

Cropping runs in your browser and creates a new PDF. The source file stays on your device for this workflow.

Features in this tool

  • Set left, right, top, and bottom margins in PDF points.
  • Apply one set of margins to selected pages.
  • Create a new PDF while keeping the source file unchanged.

Common problems and solutions

  • Important content is cut off: Use smaller margins and check the preview or exported pages before applying the change to more pages.
  • Hidden content is still present: Cropping changes the visible boundary; it is not a secure method for removing underlying page objects.
  • Pages need different crops: Run the tool separately for each group that needs a different set of margins.

Tips and limitations

  • The crop tool changes the visible page boundary; it does not erase the underlying page objects.
  • One set of margins is applied to the selected pages.
  • Keep margins within the page dimensions and review the output before relying on it.

Frequently asked about Crop PDF

Does cropping delete the hidden content?

No. It changes the page crop box rather than rewriting or removing the underlying page objects.

Can different pages use different margins?

Not in one pass. Select a group that shares margins, then run another pass for a different group.

What are PDF points?

They are the document’s measurement unit for page geometry; the tool labels the four margin fields so you can adjust them consistently.
