About Resize PDF Pages
Change the page size of a PDF to standard dimensions like A4, Letter, Legal, A3, A5, or Tabloid. Useful for printing on different paper sizes or standardizing documents. All processing happens in your browser.
How It Works
This tool loads your PDF with pdf-lib and changes the media box dimensions of each page to the selected standard size. You can choose portrait or landscape orientation.
Step by Step
- 1 Upload a PDF file
- 2 Select the target page size (A4, Letter, etc.)
- 3 Choose orientation (auto, portrait, or landscape)
- 4 Click Resize to apply
- 5 Download the resized PDF
Tips
- A4 (210×297mm) is the international standard; Letter (8.5×11in) is used in North America.
- 'Auto' orientation keeps each page's original aspect ratio direction.
- Content may need to be scaled separately — this changes the page canvas size.
