Resize PDF - fit to A4

Documents from abroad are often Letter size, and sometimes you need to scale an A3 drawing down to A4 for submission. Tap the Change page size button at the bottom left and choose from A3, A4, A5, B4, B5, Letter, or Legal; the content is centered in the new size with its proportions kept. Stamps, signatures, and text boxes scale at the same ratio.

How to use

  1. Open your PDF file and tap the Change page size button at the bottom left.
  2. Choose the size you want from A3, A4, A5, B4, B5, Letter, or Legal.
  3. Decide whether to change just this page or all pages.
  4. Check how it looks in the new size and save.

Frequently asked questions

Can I fit a Letter document to A4?
Yes. Choose A4 under Size and set Apply to to All pages; the content is centered to fit A4 with its proportions kept.
Does a landscape page turn to portrait?
No. Orientation stays the same, so landscape pages remain landscape and portrait pages remain portrait. To change orientation too, rotate the page first and then set the size.
How do stamps and signatures fit the new size?
They scale at the same ratio, and text and lines stay sharp.
Does saving a resized PDF cost anything?
Editing is free. The free version adds a light watermark on save; to save without a watermark it is $2 for a single use or $10 a year for a 1-year pass (renews automatically).
