Zero-Egress
Don’t trust us. Verify us.
The tools listed below process your PDF locally and use a stricter security policy. You can inspect their network activity and test local processing yourself. The connection policy restricts cross-origin requests; it does not by itself prove that a file was never uploaded.
Check a local processing session
- Open one of the sealed tools below and press F12 → Network tab.
- Use a non-sensitive sample PDF. Clear the request list, then process and download the file.
- Inspect all requests, including requests to this site, and their payloads. Do not filter only by filename: an upload does not have to include its filename in the URL.
- Once the tool’s required assets have loaded, disconnect from the internet and repeat. A successful offline run demonstrates local processing for that operation.
Test the connection restriction
This button tries to open an outbound connection to example.com. On a sealed page, your browser refuses — the policy won’t let this page talk to anyone but this site.
Which tools are sealed
These Zero-Egress tools carry the tightened policy and load no ads and no analytics:
Other pages can load ads and analytics. Most other tools also process PDFs locally, while some advanced editor operations use temporary backend processing. Check each tool’s processing label and our data-handling page.
What the guarantee is — and isn’t
Cross-origin connection restriction. Each sealed page ships connect-src 'self'. This restricts fetch, XHR, WebSocket and beacon connections to this origin. It still allows same-origin requests, so it is not a complete ban on uploads. Check the response header and actual network activity together.
No trackers here (our choice, checkable). We load zero ads and zero analytics on these pages — including no same-origin page-view beacon. That’s a choice we made, verifiable in your Network tab, not something the browser forces.
Honest limits: this covers the 6 sealed tools listed above. Our advanced editor uses a backend for a few heavy operations, and the AI/OCR features download models (never your file) — those pages are labeled accordingly. And a policy is delivered per visit: the real assurance is that you can re-check it every time, not that we’ve bound our own hands forever.
