Every claim on this page is auditable in 30 seconds:
- Open browser DevTools (F12 or Cmd+Opt+I).
- Switch to the Network tab and tick Preserve log.
- Run the tool with your file.
- You'll see requests for the page, library code, and ad pixels — never for your PDF.
Even better: load the page, then turn off Wi-Fi. The tool still works, because there's nowhere for the file to go.
FAQ
When do I need to flatten?
When you've filled out a PDF form and want to make sure the answers can't be changed by the recipient — e.g. a signed contract or completed application.
