How to verify in Chrome DevTools
- Open any pdfnest tool (e.g. Merge PDF).
- Press F12, switch to the Network tab, filter to Fetch/XHR, and click the clear icon.
- Drop in your file and click the action button. You'll see zero outbound requests during processing — your file never leaves the browser.
