How to Resize PDF Pages to A4, Letter or Legal

By Rashad (Razzath) · Updated November 7, 2026

Documents from different countries arrive in different page sizes. A US Letter file printed on A4 paper can be cropped or scaled oddly, and some portals only accept A4.

The Resize Pages tool changes the page canvas to a standard size and centres the content, all in your browser.

Open the Resize Pages tool

How it works

Resizing changes the paper size, and the original content is placed in the centre of the new page. Pages that are very different in shape from the target, such as a wide landscape drawing placed on a tall A4 page, will leave empty bands. The text does not turn into an image, so it remains selectable.

When this is useful

  • Converting US Letter documents to A4 for printing in the UAE or Europe.
  • Making every page in a merged bundle the same size.
  • Preparing a file for a portal that requires a specific paper size.
  • Adjusting scans of different sizes into one consistent format.
  • Printing legal-size forms on regular paper.

Step-by-step instructions

  1. Open the Resize Pages tool and select your PDF.
  2. Pick the target size, such as A4, Letter or Legal.
  3. Create the resized PDF and download it.
  4. Open the file and check the margins and the position of the content.

Tips for the best results

  • Resize before adding page numbers or watermarks.
  • Check that no content is cut off near the edges.
  • For scans, crop the white space before resizing.
  • If the print preview looks wrong, check the printer's 'fit to page' setting.

Common problems and how to fix them

Content looks small on the new page

The page shape differs from the target size. Rotate the pages first or choose a more similar size.

Part of the page is missing

Scale down the content or choose a larger paper size such as Legal.

What happens to your file?

This tool runs entirely in your browser, so your document is never uploaded to our server.

Frequently asked questions

Does resizing reduce quality?

Text and vector graphics remain sharp. The content is moved, not rasterised.
