About This Tool

This tool crops PDF documents by applying a defined crop box to selected pages or the entire document. Users provide a source PDF, specify left, bottom, right, and top margins in points, and indicate a page range if desired. The operation produces a new cropped PDF that preserves embedded fonts and images while removing content outside the crop area.\\n\\nConceptually, the tool reads the input PDF, validates page sizes, enforces unit consistency (points, with 1 inch = 72 points), applies the crop box per page, and writes a new PDF with the specified pages cropped. It clamps inputs to valid page boundaries to avoid invalid crops and maintains original metadata where possible.\\n\\nWho benefits? Professionals preparing reports, shareable documents, or legal filings that require uniform margins. It is useful for QA teams who compare originals with cropped versions or for educators producing handouts. The tool’s core differentiator is precise, per-page cropping with range support and safe defaults that prevent data loss.\\n\\nCore features include per-page crop box control, page-range application, safe validation, output naming, and a self-contained workflow. Use cases include trimming margins before printing, removing redacted areas, and exporting compact PDFs for email distribution.

Frequently Asked Questions

Find Quick Answers

What inputs are required?
To crop, supply the PDF source, crop margins (left, bottom, right, top), and an optional page range. If page range is omitted, the operation applies to all pages. The tool validates numeric inputs and page references before processing.
Can I crop by page range only?
Yes. Use the page_range input to apply the crop to selected pages. The rest of the document remains unchanged. The output is a new cropped PDF that preserves the original pages and metadata.
What happens if crop values exceed page size?
Crop values are clamped to each page's boundaries to avoid invalid results. The tool validates inputs and returns an error if the PDF cannot be cropped within its page sizes.
