What is PDF Page Resizer?

PDF Page Resizer is a free online tool that changes the page dimensions of your PDF documents.

Convert between standard sizes like A4, Letter, Legal, A3, A5, and Tabloid — or set custom dimensions in points. Choose how content fits the new size: scale proportionally, center on page, or stretch to fill. All pages are resized at once. The tool runs entirely in your browser, so your files stay private.
