Resize PDF pages when you need a standard paper size for print, or extra white margin for notes, binding, and stamps.
Choose Add margins to expand each page with equal padding, or Change page size to place content on A1–A6, Letter, Legal, Tabloid, Ledger, Executive — or a custom width × height. Fit, stretch, or center as needed. Everything runs in your browser on PDFPeach; files never leave your device.
How to resize PDF pages
- Upload a PDF.
- Choose add margins or a new page size (and fit/stretch/center when changing size).
- Download the resized PDF.
Pick units in inches or centimeters for custom dimensions so the output matches your printer or binder specs.
Why resize instead of reprinting from the source app
You often only have the PDF — not the Word, InDesign, or CAD file. Resizing in the browser adapts that PDF to the paper and margin rules you need now.
- Standard sizes — A-series, Letter, Legal, Tabloid, Ledger, Executive.
- Custom dimensions — Exact width × height when templates demand it.
- Margin mode — Grow the page with white space; keep content size.
- Free and private — Processing stays in your browser; no upload.
When to resize PDF pages
- Convert Letter exports to A4 (or the reverse) for a regional printer.
- Add binding gutter / note margins before a workshop packet.
- Normalize mixed page sizes in a merged pack to one sheet size.
- Scale content to fit a form template’s paper requirements.
- Prepare sheets before n-up or print poster workflows.

Frequently asked questions
What is the difference between margins and page size?
Margins keep the original content size and grow the page with white space. Page size places content onto a new paper dimension using fit, stretch, or center.
Does Fit keep the aspect ratio?
Yes. Fit scales content to fit inside the target page without distorting it. Stretch fills the page and may change proportions. Center keeps the original size.
Can I choose a paper standard?
Yes. Choose A1–A6, Letter, Legal, Tabloid, Ledger, Executive, or enter a custom width × height in inches or centimeters.
Are my files uploaded when I resize?
No. Resize runs entirely in your browser and is free to use on PDFPeach.
Will this create a poster from one large page?
For tiling a large page across many printable sheets, use Print Poster. Resize changes each page’s dimensions; it does not split one page into a tile grid.
