When you Google “Resize PDF”…
Your private files on someone else’s server.
You have to upload the whole file, even when you only need a small change.
Ads to watch. Credits to buy.
You finish the steps, then find out you have to pay or watch an ad to get your file.
“This format isn’t supported.”
You find a converter, but it cannot open the file you actually have.
Too many buttons. No clear next step.
A complicated interface turns a simple file task into something you have to learn.
A bad result. Another search.
The tool crashes or the result is wrong. Now you have to start again somewhere else.

Resize PDF pages when you need a standard paper size for print, or extra white margin for notes, binding, and stamps — including PDF size increase for the page itself (larger sheet or added margins).
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 ConvertPeach.
Need to reduce file size (KB/MB) for email — e.g. “resize PDF to 100 KB”, “PDF resizer 500 kb”, or pdf500kb? Use Compress PDF, not this tool.
How to resize a PDF
- Upload a PDF.
- Choose add margins (increase page size with white space) or a new page size — plus fit / stretch / center.
- 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 — No upload
When to resize PDF pages
- Convert Letter ↔ A4 for a regional printer
- Increase PDF size with binding gutter or note margins
- 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
Modes
| Mode | What it does |
|---|---|
| Add margins | Keeps content size; expands the page with equal white padding |
| Change page size | Places content onto a new paper dimension (larger or smaller) |
Content placement (page size mode)
| Option | Behavior |
|---|---|
| Fit | Scales content to fit inside the target page; keeps aspect ratio |
| Stretch | Fills the page; may change proportions |
| Center | Keeps original size and centers on the new sheet |
Supported paper targets
A1–A6, Letter, Legal, Tabloid, Ledger, Executive, plus custom width × height in inches or centimeters.
Resize vs compress vs crop
- Resize PDF — Page geometry / margins (cm, A4, Letter)
- Compress / reduce file size — Smaller KB/MB on Compress PDF
- Crop — Trim existing edges (Crop PDF)
- N-up — Multiple source pages per sheet (Multiple Pages Per Sheet)
Privacy
Resizing is local. ConvertPeach does not store your PDF on a server for this tool.
Frequently asked questions
How do I increase PDF size or add larger margins?
Choose Add margins to grow the page with white space, or pick a larger paper size and use Center / Fit. Download a new PDF — the original file is not overwritten.
How do I resize a PDF to 100 KB, 300 KB, or 500 KB?
That usually means file size, not paper size — common for PDF resizer 100 kb, 300 kb, 500 kb, or pdf500kb searches. Use Compress PDF. This Resize tool changes page dimensions (A4, Letter, custom), not a kilobyte target.
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.
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.
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.
