Change PDF Page Size Pro: Offline PDF Resizer Tool

Change PDF page size locally in your browser. Set standard or custom dimensions, add margins, and save resized PDFs without uploads.

Change PDF Page Size Pro is a practical offline browser tool for resizing PDF pages without sending files to any server. You can switch pages to standard paper sizes like A4, A3, Letter, Legal, and more, or enter a custom width and height for exact output needs. Optional margins let you add white space around the content while the tool automatically scales and centers each page to fit the new canvas. It is useful for print preparation, document standardization, cleaner sharing, and fixing files with inconsistent page dimensions. Everything runs locally on your device for privacy, speed, and simple PDF export.
