Frequently asked questions
Why would a PDF have different page sizes?
Because it was assembled. Merge a scanned receipt into a Letter report and add an A4 invoice, and you have three sizes in one file. It reads oddly on screen and prints worse, with pages jumping between trays or being scaled unpredictably.
What does “unify” do?
It finds the size the document already uses most and makes every page match it. A file that is mostly A4 with two stray pages becomes all A4 — rather than all converted to something new that none of it was.
Will anything be cut off?
No. Each page is scaled to fit inside the new size and centred, so a page going to a different shape gains a margin rather than losing its edges.
Does it stay sharp?
Yes. Pages are re-placed as vector content, so text and lines stay crisp at any size — this is not a re-scan.
Is my file uploaded?
No. Everything happens inside your browser and the document never reaches a server.
