Resize PDF Pages to a New Paper Size

Change the paper size of a PDF, or make pages of different sizes all the same.

About Resize PDF Pages

Resize PDF pages when a US Letter file has to go into an A4 binder, a print shop wants A3, or a merged document mixes phone screenshots with full-size scans. Choose the new size, A4, Letter, A3, A5, Legal, or Same as the first page to make everything match. Landscape pages stay landscape on the new paper. Files of different sizes can be combined first with Merge PDF and then made uniform here.

Scale to fit shrinks or enlarges the content proportionally and centers it, so nothing gets cut off. Keep size, add margins leaves the content at 100% and centers it on the new sheet, which suits moving to bigger paper. Text and graphics are placed rather than redrawn, so they stay sharp at any size.

FAQ

Resize PDF Pages: questions and answers

How do I resize PDF pages from Letter to A4?
Choose A4 under New page size and keep Scale to fit. Each page is scaled to fit the A4 sheet and centered, with a narrow white band where the proportions differ.
Can I resize PDF pages without shrinking the content?
Yes, pick Keep size, add margins. The content stays at 100% and gains white space around it; on smaller paper its edges would be cut, so use Scale to fit for that. To remove white space rather than add it, Crop PDF trims the margins.
Does it work with scanned PDFs?
Yes. Scanned pages are resized the same way, though a scan can't get sharper than its original resolution.
What's the largest PDF I can resize?
50 MB on the free plan, where you get 2 tasks a day, and 1 GB with VIP and no task limit. Without an account you can try it twice.
Is my PDF kept after resizing?
No. It's deleted from our server one hour after the task, together with the resized version, and it's never passed to anyone else.
