See the exact size of every page, then normalize them onto one uniform size.
Your file is analyzed and then deleted — never stored, never shared. The scan itself is completely free, no account needed.
A PDF assembled from more than one source - a scanned chapter mixed with typed pages, an exhibit stapled onto a report - often ends up with pages that aren't all the same size, which can print oddly or look inconsistent on screen. This tool rescales every page onto one uniform size you choose, always preserving the full content's proportions - nothing is ever cropped or stretched out of shape - and by default keeps each page's own portrait or landscape orientation intact.
How to use this tool
- Upload the PDF you want checked - the scan is free and shows the exact size of every page.
- Choose the target size (A4, Letter, Legal, A3, or whichever size already appears most in your document) and whether to keep each page's own orientation.
- Sign in and download the result with every page rescaled onto that one uniform size.
Frequently asked questions
Will this crop or stretch my page content?
No - every page's full content is scaled down or up to fit the new size while keeping its exact proportions. If a page's shape doesn't match the target exactly, it's centered with an even margin rather than cropped or stretched out of shape.
What happens to a page that's landscape on purpose, like a wide table?
By default ("keep each page's own orientation") a landscape page gets a landscape-shaped target of the size you chose, so it isn't forced upright. You can also force every page to one orientation if that's what you actually want.
Is checking my PDF's page sizes free?
Yes - seeing the per-page size breakdown costs nothing and needs no account. Only downloading the normalized file is charged, and your first fix on this site is free.

How to make all PDF pages the same size – step by step
A PDF built from several sources often has pages of different sizes - a scanned chapter next to typed A4 pages - which prints oddly and looks messy on screen. Page Size Normalizer measures every page and rescales them all to one size you choose, without cropping or stretching anything.
