Resize PDF is a free tool that scales every page of a PDF to a new size, entirely in your browser with nothing uploaded. Choose A3, A4, A5, Letter, Legal, Tabloid or a custom width and height in millimetres or inches, pick portrait, landscape or match-each-page orientation, set a margin, and choose Fit to keep the whole page visible or Fill to cover the page. Pages that start too big shrink and pages that start too small enlarge, keeping their proportions and keeping text selectable.

Frequently asked questions

Is my PDF uploaded anywhere?

No. The PDF is processed entirely in your browser, so your file never leaves your device. The resized PDF is built right here on your computer.

Will it resize pages that are too big and too small?

Yes. Every page is scaled to the size you choose, so oversized pages shrink to fit and small pages are enlarged, all keeping their proportions. Choose Fit to keep the whole page visible or Fill to cover the page edge to edge.

Which page sizes can I choose?

A3, A4, A5, Letter, Legal and Tabloid, or a custom width and height in millimetres or inches. You can also set orientation to portrait, landscape, or match each original page.

Does it keep text and images sharp?

Yes. The original page content is re-placed at the new size rather than turned into a picture, so text stays selectable and graphics stay crisp.

Is there a file size limit?

There is no fixed limit; it depends on your device's memory since everything runs locally. Very large PDFs use more memory, so on a phone an extremely big file may be slow.
