{# canonical_base is the OWNING tenant's origin: all 16 Peasy domains serve the same catalogue, so a page rendered by a non-owner points its canonical at the owner instead of competing with it. Falls back to this site for static/self-owned pages. #}

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. 1 Upload a PDF file
  2. 2 Select the target page size (A4, Letter, etc.)
  3. 3 Choose orientation (auto, portrait, or landscape)
  4. 4 Click Resize to apply
  5. 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.

Frequently Asked Questions

Does resizing scale the content?
This tool changes the page dimensions. Content position stays the same, so some content may be cropped or have extra whitespace depending on the size change.
What paper sizes are available?
