Resizing changes the page dimensions of a PDF — scaling pages to a standard size like A4 or Letter, or fitting mixed-size pages to a consistent format. It is useful for preparing a document for printing or for tidying a file assembled from different sources.
The operation runs locally in your browser with no upload, so your document stays on your device throughout.

Frequently Asked Questions
Will resizing affect print quality?
Scaling down reduces effective DPI slightly. Scaling up may soften image content. Text and vectors remain sharp at any size.
Can I mix page sizes in one PDF?
The current tool applies one target size to all pages. For mixed-size control, use the Organize Pages tool.
