Every claim on this page is auditable in 30 seconds:

  1. Open browser DevTools (F12 or Cmd+Opt+I).
  2. Switch to the Network tab and tick Preserve log.
  3. Run the tool with your file.
  4. 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.
