How to make every page in a PDF the same size
Upload a PDF with inconsistent page sizes and pick a target: A4, US Letter, US Legal, or matching whatever size your first page already is. Every page is scaled to fit that target without distortion and centered on the new page.
This is a common fix-up after merging documents from different sources, or scanning a mix of paper sizes into one file.
Frequently asked questions
Why would a PDF have mixed page sizes?
Usually from combining pages that started out different — scans mixed with digital exports, or a PDF merged from files created in different regions (A4 vs. US Letter). This tool makes every page consistent again.
Will this stretch or crop my content?
No — each page is scaled proportionally to fit within the target size and centered, the same way a printer's "fit to page" setting works. Content never gets stretched out of shape or cropped off.
What does "Match first page" do?
It uses your PDF's own first page as the target size, so every other page is resized to match it — useful when you already have one page at the size you want and just need the rest to match.
Does this affect annotations or form fields?
Only the page content is repositioned to the new size — annotations aren't automatically moved, so on a heavily annotated document their placement may no longer line up with the underlying content.
