About PDF Crop

The 'PDF Crop' tool lets you precisely trim the margins of every page in a PDF file by specifying inset values for the top, bottom, left, and right edges. It adjusts the CropBox of each page, making only the desired content area visible without permanently destroying the original page data.

This is useful for scanned academic papers, presentation slides, architectural drawings, and PDFs with extra whitespace around the content. You can specify margin values in either points (pt) or millimeters (mm), making it easier to work with print-oriented dimensions and document layout adjustments.

Because this tool uses the CropBox approach, it changes the visible area of each page rather than physically deleting the hidden content. If you need to permanently remove hidden content, you may need a rasterizing or redaction workflow instead. To normalize paper size after cropping, use [PDF Page Size Converter](/en/pdf/pdf-page-size-converter/). To split scanned spreads into halves, use [PDF Page Halver](/en/pdf/pdf-halve-pages/). To clean up blank pages, use [PDF Blank Page Remover](/en/pdf/pdf-blank-page-remover/). To reduce file size after editing, use [PDF Compressor](/en/pdf/pdf-compressor/). Processing runs in browser-side JavaScript.
