Crop or trim margins on PDF pages
Many PDFs include wide margins, scanner edges or headers you do not need. PdfWiseAI lets you crop the top, bottom, left, right or all margins of any page (or a range) by a chosen amount in PDF points (1 pt = 1/72 inch).
Use Crop PDF PagesHow it helps
A straightforward way to work with your document
Cropping does not resample page content — it changes the visible rectangle. The result keeps the original page stream, so quality and searchability are preserved.
The crop runs in your browser. The source PDF is not uploaded.

Professional use cases
When a private browser-based workflow helps
This workflow is useful for legal teams assembling exhibits, finance staff preparing statements or tax records, healthcare offices organizing administrative documents, and anyone handling files that should not be copied to an unnecessary conversion server.
PdfWiseAI creates a separate result and leaves the source unchanged. Review page order, image quality, visible content and the output filename before sharing the generated file.
Privacy verification checklist
Check the workflow before using sensitive documents
- Use a harmless sample file first and confirm the expected output.
- Prefer local transformations when no AI analysis is needed.
- Follow your organization’s security, legal and records policies.
- Keep originals until the generated file has been reviewed.
Local processing reduces document transfer, but it is not a certification of compliance with HIPAA, attorney-client duties or another regulatory framework.
