pdf.xyz is a privacy-first, browser-first platform. This page shows exactly what runs where in this environment — checked live, with no over-promising. It never reports on your files, only on capabilities.
7 tools run entirely on your device with WebAssembly and browser APIs. They work offline once loaded, and your files never leave the browser.
Checking worker availability…
pdf.xyz is browser-first: whenever a tool can run on your device, it does, and nothing is uploaded. A secure worker is only ever used for work the browser genuinely can't do — and only after it's clearly labeled.
The operator's view of the secure-worker stack — is it healthy, and what is the one next action? Read live from the content-free operations snapshot. It reports on capabilities and configuration only, never on your files.
Runs entirely on your device with WebAssembly and browser APIs. Files are never uploaded.
Runs in your browser when it can, with an encrypted secure-worker fallback for large or complex files.
Runs on an encrypted, isolated worker that scans, processes, and then permanently deletes your files.
Runs on secure AI infrastructure. Your content is processed to answer your request and is never used to train models.
Secure-worker, hybrid, and AI tools show an honest, implementation-ready preview until their backend is enabled — pdf.xyz never fakes processing in the browser. See the worker architecture and security docs for how uploads, scanning, isolation, and auto-delete work.
