Resize / scale PDF pages
Scale every page up or down. Runs entirely on your device.
Runs on your device. The file is never uploaded.
Resize / scale PDF pages multiplies every page by a factor: either your scale setting, or one derived per page from a target width in points. Content scales with the page, so text stays vector and images keep their pixels. Both axes take the same factor, so you cannot force an exact height or a named paper size.
Questions
What is the difference between scale and width?
Scale multiplies the page size, 0.5 is half. Width sets an exact target in points and works out the factor per page, which is how you make a mixed-size document uniform. If you set width, scale is ignored.
Does scaling blur text or images?
No. PDF content is scaled as vector geometry, so text stays sharp at any size and images keep their original pixels, they simply cover a different area on the page.
Will this make my file smaller?
Barely. Scaling changes the page geometry, not the data inside it. For file size, use Compress PDF.
What size is A4 in points?
595 by 842. Letter is 612 by 792. Set width to one of those to normalise a document to that paper width.
