What this tool does

Papiral resizes the page dimensions of every page in your PDFs to a standard paper size — A4, US Letter, US Legal, A3 — or to custom dimensions you specify in points. Landscape orientation is also supported. Process an entire batch in one job. Note: page content is not scaled; the page box is resized and content may clip or gain whitespace.

Frequently asked questions

Is the content scaled to fit the new page size?

No — only the page box dimensions change. Content that extends beyond the new size may be clipped, and content smaller than the new size will have extra whitespace around it.

Can I set a custom page size?

Yes — choose 'Custom' and enter width and height in points. 72 points = 1 inch, 28.35 points ≈ 1 cm.
