How to Programmatically Crop and Resize PDF Pages

Share this page

Gain precise control over your document dimensions and visual content by learning how to programmatically crop and resize PDF pages using the pdfRest Set Page Boxes API Tool. This specialized REST API enables developers to set or edit the MediaBox (page size) and CropBox (visible content area) to adjust and standardize page boundaries. If you're looking for an automated solution to programmatically crop PDFs or resize PDF pages, pdfRest offers powerful and accurate controls for all your document processing needs.

Why Programmatically Crop and Resize PDFs?

Crop Unwanted White Space: Set the CropBox to focus on essential content, removing unnecessary margins and improving the viewing experience for your documents. This is especially useful for optimizing scanned documents.
Resize for Consistency: Control the overall dimensions of your PDF by setting the MediaBox, allowing you to standardize page sizes across a batch of documents for consistent archiving or printing.
Prepare for Professional Printing: Configure the BleedBox and TrimBox to extend content beyond the final cut line, ensuring accurate trimming and eliminating white edges in professionally printed documents.
Define Artwork Boundaries: Use the ArtBox to define the precise boundaries of artwork or visual elements on the page, which is crucial for design and prepress workflows.
Automate at Scale: Easily automate the adjustment of page boundaries across a large volume of documents, saving time and reducing manual intervention.

How to Programmatically Set PDF Page Boxes with pdfRest

Here’s a simple example of how to use cURL to send a request to the pdfRest API to programmatically set a CropBox and BleedBox for a PDF, following a specific JSON structure:

curl -X POST "https://api.pdfrest.com/pdf-with-page-boxes-set" \
-H "Accept: application/json" \
-H "Content-Type: multipart/form-data" \
-H "Api-Key: YOUR_API_KEY" \
-F "file=@/path/to/your_document.pdf" \
-F "boxes={\"boxes\":[{\"box\":\"crop\",\"pages\":[{\"range\":\"1-10\",\"left\":36,\"top\":36,\"bottom\":36,\"right\":36},{\"range\":\"11-last\",\"left\":72,\"top\":72,\"bottom\":72,\"right\":72}]},{\"box\":\"bleed\",\"pages\":[{\"range\":\"1-last\",\"left\":144,\"top\":144,\"bottom\":144,\"right\":144}]}]}" \
-F "output=resized_document"

Replace YOUR_API_KEY with your actual pdfRest API key and adjust the file path to your PDF. The boxes parameter is a required JSON string that defines the specific page boundaries you want to modify, allowing you to customize settings for different pages or box types in a single request.
