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.
