Frequently asked questions

How does the tool detect a blank page?

The page is rendered as an image and every pixel colour is analysed. Pages with more than 99.5% white pixels are considered blank.

What if a page has a light grey background?

That is also recognised as blank. Only pages with visible content (text, lines, images) are kept.

Are my files uploaded?

No. Everything happens in your own browser. Your file never leaves your device and is not stored anywhere.

Is it free?

Yes, completely free, without watermark or account. The site is paid for by ads.

Why in the browser?

PDFrust runs entirely in your browser using WebAssembly and modern JavaScript libraries such as pdf-lib and PDF.js. Your file is never sent to a server — all processing happens locally on your device. This means your documents remain private by design, regardless of what they contain. There is no account required, no file size limit, and nothing is stored after you close the tab.
