Your privacy, by architecture

PDF Editor AI is a static web app with no backend that accepts your file. Every operation runs inside your browser tab using pdf-lib and PDF.js. You can verify this by opening DevTools and watching the Network tab — there is no outbound request carrying your document. Disconnect from the internet after the page loads and the tool keeps working. There is no account, no telemetry on your files, and no third-party data processor in the loop.

Frequently asked questions

Do my PDF files leave my device?

No. PDF Editor AI runs entirely in your browser using WebAssembly and JavaScript. Your file is opened from your local disk, processed in memory inside the browser tab, and the resulting PDF is saved back to your device. No file is ever uploaded to a server, queued, logged, or stored. You can disconnect from the internet after the page loads and the tool still works.

Does it work offline?

Yes. After the first visit the assets are cached by your browser. You can open the tool with no internet connection and continue working. This makes PDF Editor AI safe for handling confidential legal, medical, and financial documents on locked-down networks.
