Change the page size of a PDF
Choose a PDF and a page size. Every page is scaled to fit the new size on your device, and nothing is uploaded.
Each page keeps its own orientation and proportions, and is centred on the new size.

How to change the page size of a PDF
Choose your file, or drop it on the box above.
Pick a page size, or choose Other and type the width and height in millimetres.
Select Resize pages and save the new file.
How each page is fitted
Each page is scaled to fit the new size without stretching, and centred: a US Letter page on A4 fills its width with a small band above and below. A landscape page stays landscape.
Text and drawings stay sharp, because nothing is turned into an image, and links and form fields move with what they cover.
Paper sizes
A4 is 210 × 297 mm and A3, A5 follow ISO 216. Letter is 8.5 × 11 inches, Legal 8.5 × 14 and Tabloid 11 × 17, the US paper sizes.
Your file never leaves your device
The pages are resized in your browser with qpdf, an open-source PDF library built to run on your device. No file, page or file name is sent to us or to anyone else. The tool itself loads only when you start, so the page stays fast.
How large can the file be?
It depends on your device's memory. If the file is too large for your device, the tool says so before it starts, rather than letting the browser close the tab.
A file protected with a password opens once you type its own password on this page, and the new file has no password. We never get around a file's protection.
