Frequently asked questions

What happens to pages that are already the right size?

They are processed too but the content does not change.

Does the text layer stay intact?

Yes. The content is scaled or shifted, not rasterized. Text stays selectable.

Which sizes are available?

A4, Letter, A3, A5 and Legal, in both portrait and landscape orientation.

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.
