Resize PDF pages

Resize the pages of a PDF to a standard paper size so it prints cleanly and looks consistent. Pick A4, Letter, Legal, A3, or A5 and choose portrait or landscape. This fixes documents that were built at odd dimensions or that mix page sizes. Your file is processed securely and deleted right after.

When to use this tool

• A PDF was built at a non-standard page size and doesn't print cleanly on regular paper.
• You're combining pages from different sources that came out at different sizes.
• A form needs to match a specific paper size, like Letter in the US or A4 elsewhere.
• You want to switch a document from portrait to landscape without redesigning it.
• You're printing at a copy shop that requires a specific standard page size for binding.
• Pages copied from multiple sources need to look uniform before they're combined into one packet.

Tips for a better result

• Pick the paper size your printer or recipient actually uses: Letter in the US, A4 in most other countries.
• Resize before merging documents from different sources so the final file has one consistent size.
• Check margins after resizing, since content is scaled to fit rather than cropped.
• If only orientation is wrong, keep the original size and just switch portrait or landscape.
• Print a single test page after resizing if the document's exact dimensions matter for a specific use.

Privacy: what happens to your file

This tool uploads your file to our server, which forwards it to a self-hosted PDF engine to scale every page to the size you choose, then streams the result straight back to your download. Our own server doesn't write a copy to disk or share your file with anyone else.
