Free Online PDF Resizer — Change Page Size to A4 or Letter
If you're trying to print a document that was formatted for US Letter paper, but your printer only has A4 paper (or vice versa), you might encounter margins being cut off. Our Resize PDF tool solves this by recalculating and scaling your document to fit perfectly onto standard paper sizes.
Available Page Sizes
- A4 (210 × 297 mm): The standard paper size used in most of the world outside of North America.
- US Letter (8.5 × 11 in): The standard paper size used in the United States, Canada, and parts of Latin America.
- Legal (8.5 × 14 in): A longer paper format frequently used for contracts and legal documents in North America.
How We Resize Your PDF
Instead of stretching your text and images (which would distort them), our tool uses proportional scaling. We embed your original pages into a new canvas of the target size, scaling them down or up while maintaining their original aspect ratio. This ensures your charts, text, and photos remain perfectly crisp and undistorted.
