Frequently Asked Questions

What page sizes are available?

You can also enter custom dimensions in inches or millimeters.

Does resizing distort or stretch my content?

No. Content is scaled uniformly - width and height scale by the same factor - so your text, images, and graphics keep their original aspect ratio. The scaled content is centered on the new page.

What is the difference between Letter and A4?

US Letter is 8.5 x 11 inches (216 x 279 mm). ISO A4 is 210 x 297 mm (8.27 x 11.69 inches). A4 is slightly narrower and taller. Converting between the two is one of the most common reasons to resize a PDF.

Can I enter a custom page size?

Yes. Select Custom from the dropdown, then enter your desired width and height. You can choose inches or millimeters as the unit. The tool converts your values to PDF points (72 points per inch) automatically.
