About This Tool
Crop PDF changes page boundaries to trim margins or focus on a selected region. The underlying page content outside the crop can remain in the file even when it is no longer visible.
What You Can Do
Page-box editing
Set a visible crop region for selected pages.
Preview-guided trimming
Use the page display to judge the intended boundaries.
Page selection
Apply crop settings to the required pages.

Practical Use Cases
Margin cleanup
Trim excessive scanner borders before presentation.
Focused handouts
Show a specific portion of oversized technical pages.
Privacy and File Processing
Crop PDF keeps its PDF input in browser memory while the operation runs. The workflow creates PDF for local preview or download and does not send the entered values or selected file bytes to the GXA Toolbox application server.

How It Works
PDF crop boxes are updated to the selected page rectangle so viewers expose that region; cropping does not securely erase content outside the visible box.
Limitations and Important Notes
- Cropping is not secure redaction; hidden content may remain recoverable.
- Different page sizes can require individual review.
- Very tight crop boxes may clip annotations or printing marks.
Worked Example
Trim a half-inch scanner border from each page of a letter-size document while keeping all text inside the new bounds.
Helpful Tips
- Leave a small safety margin around content.
- Use a redaction product—not cropping—to remove sensitive information.
Frequently Asked Questions
Does cropping delete hidden content?
Not necessarily. It changes visible page boundaries and is not redaction.
Can I crop selected pages?
Use the page-selection controls available in the crop workspace.
Does crop change page orientation?
It changes page bounds; use Rotate PDF for rotation.
