Changing PDF Page Sizes

[lexus]

I have a huge 500 page PDF the problem is some are A3 sized and I need them all to be A4. Does anyone know how to make them all the same size in Preview?

Im sure their must be a way.

Any help is greatly appreciated.

Thank you.

Print it to a new PDF, selecting "scale to fit/fill entire paper" in the options. That's likely to work.

In case you aren't aware of how to do this: cmd-P for print, click the little triangle if the options aren't open, select scale to fit and fill entire paper, and instead of the Print button hit the PDF button in the lower left.
