How to Resize a PDF
Need to resize a PDF? ToolifyPDF is a free online tool that changes the page size of your PDF documents in seconds, right in your browser. Convert a PDF from US Letter to A4 for printing, shrink an A3 poster to A4, or set an exact custom size in millimeters, centimeters, or inches. Every page is resized to the size you choose, and your content is scaled without being stretched, so text and images keep their proportions. Resize one PDF or up to 30 at once. No software to install, no account needed. Want a smaller file instead of a smaller page? Use our Compress PDF tool.
All Standard Paper Sizes
Resize PDF files to A0, A1, A2, A3, A4, A5, A6, Letter, Legal, Tabloid, or Executive, in portrait or landscape. Perfect for switching between A4 and US Letter or preparing a document for a print shop.
Custom Size, Whole Page Kept
Enter an exact width and height in millimeters, centimeters, or inches. Every page is scaled to fit the new size and centred, so nothing is ever cut off or stretched.

FAQ
How do I resize a PDF?
Upload your PDF to ToolifyPDF, choose the new page size, and click Resize PDF. Every page of your document is changed to the new size in seconds. You don't need Adobe Acrobat or any other software.
Is this PDF resizer free?
Yes. ToolifyPDF lets you resize PDF documents for free, with no hidden fees, no watermark, and no sign-up. You can resize as many PDF files as you need.
Will any part of my pages be cut off?
No. Each page is scaled to fit the new page size and centred. When the proportions differ, small white margins are added instead of cutting anything, and the content is never stretched.
How do I resize a PDF to A4 or Letter (8.5 x 11)?
Choose A4 or Letter from the page size menu, select portrait or landscape, and click Resize PDF. Letter is the standard 8.5 x 11 inch paper size used in the United States, while A4 is used in most other countries.
Can I resize a PDF to a custom size?
Yes. Choose Custom and enter the width and height in millimeters, centimeters, or inches. This is useful for print shops, posters, booklets, or any special paper size.
Does resizing a PDF reduce its file size?
No. This tool changes the page dimensions, not the file size. To make your PDF file smaller, for example to send it by email, use our Compress PDF tool.
Will the text stay sharp and selectable?
Yes. Your pages are scaled, not turned into images, so text stays sharp, selectable, and searchable. Links and bookmarks from the original PDF are kept and still point to the right place.
How do I resize a PDF on Mac?
On a Mac, you can open the PDF in Preview, choose File > Print, pick a paper size and Scale to Fit, then save it as a PDF. With ToolifyPDF, you can resize several PDF files at once in any browser and every page is kept whole.
Can I resize several PDF files at once?
Yes. Upload up to 30 PDF files, up to 200MB each, and they are all resized to the same page size. Password-protected PDF files are supported too: you'll be asked for the password.
Is it safe to resize PDF files online?
Yes. Your files are uploaded over encrypted HTTPS connections and processed on secure servers. All uploaded and resized files are automatically deleted one hour after processing, and we never share your documents with third parties.
Advanced Features
Beyond basic resizing, our PDF resizer offers several advanced features:
- Standard Sizes: A0 to A6, Letter, Legal, Tabloid, and Executive.
- Custom Dimensions: Enter any size in millimeters, centimeters, or inches.
- Auto Orientation: Each page keeps its own orientation (landscape pages stay landscape), or choose Portrait or Landscape for all pages.
- Whole Page Kept: Pages are scaled to fit and centred, never cropped.
- No Distortion: Content is scaled proportionally, never stretched.
- Batch Resizing: Resize up to 30 PDF files at once, including password-protected files.
💡 Pro Tip
Printing a US Letter PDF on A4 paper (or the other way around)? Nothing gets cut off: the content shrinks slightly and gets small margins, but every word stays on the page.
Privacy & Security
We take your privacy seriously. All file uploads and processing happen over encrypted HTTPS connections. Your files are automatically deleted from our servers after one hour, and we never store or share your documents with third parties. You maintain complete control over your data at all times.
