What is a resize PDF pages?

This tool changes the paper size of every page in a PDF. Pick A4, US Letter, Legal, A3, A5 or type a custom width and height in millimetres or inches, choose portrait, landscape or Auto (each page keeps its own orientation), and add a margin if you want white space around the content. Each page's content is scaled to fit the new size, keeping its proportions, and centred. A before-and-after preview shows the result for any page.

The page is resized in place rather than printed again as an image, so text stays sharp and selectable, and links and form fields are moved and scaled with the content.

Limits: this changes the page size, not the file size (to make the file smaller, use a PDF compressor). When the old and new shapes differ, for example Letter to A4, the content is scaled down slightly and white space appears on two sides; nothing is cut off or stretched. Comments drawn as freehand ink may shift slightly on unusual files.

Why use a resize PDF pages?

Printers, courts, universities and visa portals often accept only one paper size, and a US Letter PDF printed on A4 (or the other way round) gets clipped or shrunk unpredictably. Resizing the PDF first gives you pages that print exactly as expected, without uploading the document anywhere.

Resize PDF pages: frequently asked questions

How do I convert a US Letter PDF to A4?

Choose A4 and keep Auto orientation. Each Letter page is scaled to about 97% and centred on A4 paper, so nothing is cut off. A4 to Letter works the same way.

Will my text become blurry?

No. The page content is scaled as vectors, not turned into an image, so text and drawings stay sharp at any zoom and you can still select and search the text.

Does resizing make the file smaller?

No, it changes the paper size only; the file size stays about the same. To reduce the size in MB, use a PDF compressor after resizing.

Can I resize pages without scaling the content?

Not in this tool: content is always scaled to fit the new page. To remove white space around the content instead, use Crop PDF.

What happens to pages with different sizes?

Every page is put on the size you choose, so a mixed document becomes uniform. With Auto, landscape pages stay landscape and portrait pages stay portrait.

Is my PDF uploaded?

No. Your browser resizes the PDF on your device. Our server only counts the run for the daily free use and credits, and never receives the file.

Is it free?

Each tool gives you 1 free run per day. After that, each run costs 5 credits with a free AI Rank Lab account. One run resizes every page of one PDF.
