Resize Information

About PDF Resizer

This tool allows you to resize PDF pages to different paper sizes or custom dimensions. You can scale PDFs by percentage, convert between paper formats like A4 and Letter, or set exact custom dimensions. All processing happens in your browser for complete privacy.

What paper sizes are supported?

We support all common paper sizes including ISO standards (A3, A4, A5, A6, B4, B5) and US standards (Letter, Legal, Tabloid, Executive). You can also specify custom dimensions in millimeters, inches, or points.

How does content fitting work?

There are four fitting options: Fit maintains the original aspect ratio and centers content; Fill scales to fill the page (may crop edges); Stretch distorts content to exactly fill the page; Center places content at original size in the center of the new page.

Can I resize specific pages only?

Yes! You can choose to resize all pages or specify individual pages and ranges. For example, entering '1, 3, 5-10' will only resize pages 1, 3, and 5 through 10.

What does the scale percentage do?

Scale percentage uniformly resizes pages. 50% makes pages half size, 200% doubles the size. The page dimensions change proportionally, so a 50% scale on an A4 page results in roughly A6 size.

Will resizing affect PDF quality?

Resizing preserves the original PDF content. When enlarging, quality depends on the original. When shrinking, quality is maintained. Vector graphics and text remain sharp at any size.

What is the background color option for?

When the new page is larger than the scaled content, the background color fills the empty space. Default is white, but you can choose any color for your needs.

What is the file size limit?

The maximum file size is 50MB. This ensures smooth processing in your browser. For larger files, consider splitting the PDF first or using desktop software.

Is my PDF file secure?

Absolutely! All PDF resizing happens directly in your browser. Your file is never uploaded to any server. Everything stays completely private on your device.
