Printers reject odd page sizes, and mixing A4 and Letter pages in one document looks messy. This tool re-draws every page onto your chosen paper size — A4, Letter, Legal, A3, A5, or Tabloid — scaling the content proportionally and centering it, so nothing gets cropped or stretched.
The auto orientation option keeps landscape pages landscape, or you can force everything to portrait or landscape. Everything runs locally with pdf-lib; your document is never uploaded.

FAQ
Will my content get stretched?
No. Pages are scaled proportionally to fit the target size and centered, so the aspect ratio never changes.
Does resizing affect quality?
Content is embedded as vector data, not re-rendered — text and graphics stay perfectly sharp at any size.
