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
Is the watermark behind or in front of the content?
In front. To keep it visible, opacity is set to 35% by default.
Can someone remove the watermark?
Yes. A diagonal text watermark is a visual deterrent, not encryption. To truly hide information, use True Redact.
