Crop PDF

Adjust one visible crop rectangle and apply it to every page of a PDF.

Processing

The PDF is cropped in browser memory and this workflow does not send the document to a Stocknivo conversion endpoint. The preview may load the PDF.js script from cdnjs; its worker is served by this site. These are runtime assets, not document uploads. This tool is not fully offline.

How it works

Choose one PDF, then adjust the same normalized crop rectangle for all pages with the preview handles or the percentage fields. The operation changes each page's CropBox and leaves its MediaBox unchanged.

Limits and important distinction

The input may be up to 50 MiB and 200 pages; output is limited to 100 MiB. One normalized crop rectangle is applied to every page and changes the CropBox, not the MediaBox; each resulting dimension must be at least 1 pt. Pages with existing rotation are rejected. Content outside the CropBox remains in the PDF and may be recoverable. Cropping is not redaction, and advanced PDF structure preservation is not guaranteed.
