PDF Page Size Changer

Make every page A4, Letter or a custom size.

Mixed page sizes — A4 pages next to Letter or Legal — cause odd margins and printing problems. See every size in your PDF and convert all pages to one size, without distorting the content.

How to use

  1. Choose a PDF to see its page sizes.
  2. Pick the target size and orientation.
  3. Choose Fit, Fill or Centre, and an optional margin.
  4. Apply and download.

Fit, Fill and Centre

Fit scales content to fit entirely on the new page, which can leave white borders. Fill scales it to cover the page and trims whatever overflows. Centre keeps the original scale and places it in the middle. Proportions are always preserved.

Frequently asked questions

Is my PDF uploaded to a server?

No. ZIYNU's PDF tools run in your browser using your device's processor. The file is opened locally and the result is created on your device, so documents such as CNIC scans, degrees and contracts never leave it.

What size is A4 in points?

595 × 842 points (210 × 297 mm). US Letter is 612 × 792 points (8.5 × 11 in).

Will text stay sharp?

Yes. Pages are placed as vectors, not converted to images.

Why won't my password-protected PDF work?

Encrypted PDFs can be read but not changed without removing the protection. Open the file in the software that created it, remove the password or restrictions, save it, and try again.
