About changing PDF page size
Choose the sheet, then choose how content fits
A PDF page has a physical width and height measured in points. Changing page size creates a new sheet geometry; it is different from compressing the file or simply hiding content with a crop boundary.
A4 is common internationally, while Letter is standard in the United States and Canada. Legal, Tabloid, Executive and ISO A-series sizes support different print and document workflows. Custom dimensions are useful for labels, books, portfolios and production specifications.
Contain keeps every source edge visible. Cover fills the target and can clip an edge. Actual size retains physical scale where possible, while stretch fills the exact rectangle and may distort content. Review mixed portrait and landscape pages before downloading.

Frequently asked questions
Answers before you resize
Open any question with the + button. FAQs stay compact in two columns on larger screens.
Which PDF page sizes are supported?
Choose ISO A0 through A6, Letter, Legal, Tabloid, Executive, square, or enter custom dimensions in millimetres, inches or points.
Can I resize only selected PDF pages?
Yes. Apply the new size to all pages, odd pages, even pages or a custom range such as 1-3, 6 and 9-12.
What is the difference between contain, cover, actual size and stretch?
Contain preserves all content inside the target area, cover fills the area and may crop, actual size keeps the original scale where possible, and stretch fills both dimensions but can distort content.
Is changing page size the same as compression?
No. Page-size changes affect sheet dimensions and placement; Compress PDF targets file size.
Are files uploaded?
Selected files are processed in your browser and do not need to be uploaded to Nexynto Tools servers.
