How local processing works
QPDF sends your browser the software, not the other way around. The PDF engines run inside the page using JavaScript and WebAssembly, so your document never needs to travel to a server.
Choose a file
Your browser reads the PDF from your device into memory. Nothing is sent over the network.
Process in your browser
The tool works on your device’s processor. Supported tools keep working even with Wi-Fi switched off.
Save the result
The finished PDF is created in memory and saved straight to your device. Close the tab and it is gone.
