Resize one page, selected pages, or whole PDFs

Select the pages you want, open Resize from the selection toolbar, choose the target page size, and resize pages in one batch from the browser workspace.

Files stay local in your browser for normal ChameleonPDF workflows.

Open ChameleonPDF

How it works

Select the pages
Select one page, Ctrl-click individual pages, Shift-click a range, use a PDF column checkbox to select a whole PDF, or press Ctrl+A to select all pages in the workspace.
Open the resize tool
The selection toolbar appears when at least one page is selected. Choose Resize from that toolbar.
Choose the target size
Pick the target page size in the resize dialog, such as A4, Letter, or another supported preset.
Resize pages in one go
Click Resize pages and ChameleonPDF resizes the selected pages together, whether you selected one page or hundreds.

Selection options

Resize a single page, Ctrl-click individual pages, Shift-click a range, select an entire PDF using the checkbox in the top-left corner of the PDF column, or press Ctrl+A to select every page in all open PDFs.

Image quality note

If selected pages contain images, enlarging those pages can sometimes make the images appear softer because the same image data is being displayed at a larger size.

FAQ

Where is the resize pages tool?

Select at least one page first. The selection toolbar appears, and the Resize tool is available from that toolbar.

Can I resize multiple PDF pages at once?

Yes. Select multiple pages and choose Resize. ChameleonPDF resizes the selected pages together.

How do I select a range of pages?

Use Shift-click to select a continuous range, or Ctrl-click to add individual pages to the current selection.

Can I resize an entire PDF?

Yes. Use the checkbox in the top-left corner of the PDF column to select all pages in that PDF, then choose Resize.

Can I resize every page in the workspace?

Yes. Press Ctrl+A to select all pages in all open PDFs in the workspace, then run the resize tool.

Will enlarging pages affect image quality?

If selected pages contain images, enlarging those pages can sometimes make the images appear softer because the same image pixels are being displayed larger.

Are PDFs uploaded when I resize pages?

For normal ChameleonPDF workflows, PDF contents are processed in your browser rather than uploaded to ChameleonPDF servers.
