PDF Crop

Crop pages (pdf-crop)

Crop pages

Part of the Universal PDF Management & Creation Skill Repository. Category: PDF Management. Every skill is individually callable (INDIVIDUAL MODE) and may also be invoked automatically by the orchestrator (SYSTEM MODE).

When to use

Trim edges / white borders of pages.

Operations

• uniform margin crop
• asymmetric insets
• selected pages

Engine (what actually executes this)

universal_pdf/core.manipulate:crop_pdf

All heavy lifting is done on disk / one page at a time by the shared engine — never by loading the document into an LLM context.

Tools & graceful degradation

• Preferred tool: PyMuPDF set_cropbox/mediabox
• Fallback: —

If the preferred backend is unavailable the skill transparently uses the fallback or reports a documented limitation. It never reports success when an operation did not actually happen.
