Change PDF from letter to legal?

Good morning. My research is based on people with vision problems. I’d like to share a textbook in PDF format that we created a while ago in 8x11 in a larger font size. I see that it is possible to change font but I’m thinking the only way to increase font size while retaining page numbers is to change from letter to legal. Is this possible using Infix?

Thank you!

You should be able to do this using the Document->Pages->Resize… menu.

Regards, Simon.

This worked. Thank you!!!
