About Resize PDF Pages
What this tool does
Resize PDF Pages changes the page dimensions of a PDF to A4, Letter, Legal or a custom size, in portrait or landscape.
How to use it
- Upload your PDF.
- Pick a target page size and orientation.
- Download the resized PDF.
How it works
Each page's media box is set to the target size with pdf-lib and the content is scaled to fit, keeping proportions.
Important considerations
- Content is scaled to fit; very different aspect ratios add margins rather than distort the page.
Privacy
Your PDF is processed entirely in your browser. The file is never uploaded to a server, which makes this safe for confidential contracts, statements and personal documents.
