Change PDF Page Size
Rescale every page of a PDF to fit A4, US Letter, or Legal size.
This tool stays free by showing a short ad for larger files: 20 pages or fewer is free, 21-50 pages = 1 ad, 51-100 pages = 2 ads, 100+ pages = 3 ads.
How it works
Content is scaled proportionally to fit the new page size and centered, so nothing gets stretched or distorted.
Is my file uploaded anywhere?
No — everything happens locally in your browser. Your PDF never leaves your device.
