We re-engineered the PDF editor to remove the biggest vulnerability: the cloud. With CrushPDF, your sensitive documents stay exactly where they belong—on your computer.
Traditional tools upload your files to a cloud server. We don't. All processing happens locally within your browser using WebAssembly. Your data physically never leaves your device.
We utilize AES-256 encryption standards directly in the browser. When you password-protect a file, the cryptographic operations occur instantly on your machine.
We don't track your file contents, metadata, or reading habits. Since we don't host your files, we can't see them even if we wanted to.
By design, we are compliant with major privacy regulations. We do not act as a data processor for your documents because we never possess them.
Don't just take our word for it. Open your browser's "Network" tab while using CrushPDF. You will see zero file uploads. That's the power of client-side engineering.
