Resize PDF pages online — A4, Letter and more
Got a Letter-size PDF that needs to print on A4, or a mix of page sizes that should match? Our Resize PDF tool puts every page on the paper size you choose: the content is scaled to fit (or to fill the page), centred, with an optional margin, and the orientation can follow each page automatically. Nothing is turned into an image — text stays selectable and graphics stay sharp, and links move with the content. The resized PDF opens in the Mega AI Studio.
Every common size
A4, Letter, Legal, A3, A5 and Tabloid, portrait or landscape.
Fit or fill
Keep the whole page visible, fill the paper, or stretch to the exact size.
Stays sharp
Text and vectors are scaled, not turned into pictures.
