Your PDF is processed locally in your browser.
PDFSimplify processes documents on your device using client-side WebAssembly and Web Workers. No document data is transmitted to our servers or external cloud services during processing.
How Resize PDF Works in Your Browser
Creates a new document canvas with the target dimensions directly in your browser. Embeds source pages as vector content streams with proportional scaling and centering, preserving crisp vector typography.
Why client-side processing is more private:
Unlike conventional online converters, your documents never traverse external networks to third-party processing servers. Everything happens inside your local machine’s memory.
