Change PDF page size online
Rescale every page in a PDF to a standard paper size — US Letter, A4, Legal, A3, A5, or Tabloid — the fix for a document formatted for the wrong region's default paper, or one you need to reprint at a different size.
This scales the actual page content to the new dimensions, not just the page's outer box — text, images, and layout are resized together, so the page still looks like itself, just at a different size.
Your file never leaves your device. Resizing runs entirely in your browser, so nothing is uploaded, stored, or scanned.

Frequently asked questions
Is my file uploaded anywhere?
No. Resizing runs in your browser using JavaScript, so your file stays on your device. You can confirm this by opening your browser devtools Network tab while working — there are no upload requests.
Why would I need to change page size?
Most commonly because a document was made for a paper size your country or your printer does not default to — US Letter versus A4 is the classic mismatch between North America and most of the rest of the world. Converting beforehand avoids a printer awkwardly shrinking or cropping the page to fit.
Does this distort the content?
Very slightly, if the source and target proportions differ — Letter (8.5 × 11 in) and A4 (210 × 297 mm) are close but not identical in shape, so fitting one exactly into the other stretches it a small amount in one direction. It is not usually visible at a glance, and it is the trade-off every tool that does this exact conversion makes, rather than leaving empty margin instead.
Does this work on every page, or just the first one?
Every page in the document is rescaled to the size you choose.
What happens to form fields or comments?
They are rescaled along with the page content, so they stay aligned with whatever they were pointing at.
Can this convert a password-protected PDF?
Not directly — unlock it first, using a password you know.
