About this tool
Pick a target size; each page is placed on a new page of that size, scaled proportionally to fit (default) or stretched, keeping landscape pages landscape. Content stays vector, so there is no quality loss. Typical uses: Letter documents for an A4 office, mixed-size scans made uniform, or a portal that insists on A4.
Nothing is uploaded.
How it works
- Step 1. Choose or drop the PDF(s).

- Step 3. Press Resize and download.
Questions
Will text get blurry?
No — pages are embedded as vector content and scaled.
What is the difference between fit and stretch?
Fit keeps proportions and centres the page with margins if needed; stretch fills the new size exactly and may distort slightly.
Can I resize only some pages?
Resize applies to all pages; split the PDF first if you need different treatment.
