Privacy by default.

SilentPDF was built on a simple premise: your documents should stay your documents. In a world where every file uploaded to the cloud is at risk of being logged, indexed, or monetized, we decided to take a different approach.

How it works

By leveraging the power of WebAssembly and modern browser APIs, SilentPDF brings the processing power directly to your device. When you merge, split, compress, or rotate a PDF on our platform, the heavy lifting is done locally by your CPU and memory.

The bytes never leave your machine. There is no upload progress bar to our servers, and there is no "download from the cloud" link when you're done.

Our Mission

We believe that fast, reliable, and secure document processing should be available to everyone without compromising on privacy. Our mission is to continue expanding the capabilities of client-side computing so that you never have to blindly trust a third-party server with your sensitive data again.
