About this tool

Changes every page to a standard paper size so the document prints consistently. Handy when a PDF mixes page sizes, or when a document authored for Letter needs to print on A4 without the printer scaling it unpredictably.

Frequently asked questions

Is the content scaled to fit?
Yes. The page box is set to the target size and the content is scaled to match, preserving the layout.
Which size should I choose?
A4 is standard outside North America; Letter is standard in the US and Canada. Legal is for longer documents such as contracts.
Will this fix a document with mixed page sizes?
Yes. Every page ends up the same size regardless of what it started as.
Does it change the aspect ratio?
Content is scaled uniformly, so proportions are kept. A differing aspect ratio results in margins rather than stretching.
