Resize PDF pages

Choose a target paper size and orientation, or a percentage scale. All processing happens locally, nothing is sent to a server.

How Resize PDF pages works

PDF resize scales every page of a PDF to a standard paper size, A4, Letter, Legal, A3 or A5, or to a custom percentage of the original dimensions. It recalculates the page dimensions and rescales the content proportionally so the result prints or displays correctly at the new size.

This is useful when a PDF arrives in a non-standard size and you need it to match a print run, or when you want a compact A5 version of an A4 document for reading on a small screen. Native vector content stays sharp at any size because it is rescaled mathematically; raster images are scaled too, so they can soften if you enlarge significantly.

Frequently asked questions

Are my files uploaded to a server?

No. Every operation runs inside your browser tab using JavaScript and WebAssembly. Your file is read into memory on your own device, processed there, and the result is offered as a local download. Nothing is transmitted to Sunasty or any third party. You can verify it yourself: open your browser DevTools, go to the Network tab, and watch, no request carries your file.

Does resizing affect text quality or make text blurry?

For PDFs with native vector content (text, lines and vector graphics), the output stays sharp at any size because the content is rescaled mathematically. If a page contains raster images those will be scaled too, which can reduce their apparent sharpness if you enlarge significantly.

Can I resize only some pages rather than all of them?

The tool applies the chosen size uniformly to every page. If you need different sizes per page, split the PDF first using the PDF organise tool, resize each batch separately, then merge them back.

Does it work offline?

Yes, once the page has loaded. Because the processing happens on your device, you can disconnect from the network and the tool keeps working. This is the clearest proof that your data never leaves your machine.

Is it free? Do I need an account?

It is completely free and requires no sign-up. There are no watermarks, no daily limits and no tracking cookies needed to use the tool.
