FAQ
How is this different from drawing a black box?
A normal box only covers text visually — it can still be copied from underneath. Here, covered pages are turned into images, so the hidden text is removed for good.
Are other pages affected?
No. Only pages with black boxes become images; the rest stay unchanged.
Is my file uploaded?
No — for a sensitive document that matters most: everything runs in your browser.
Are my files safe?
Yes. Everything is processed on your device and nothing is uploaded to a server.
Is this tool free?
Yes, completely free and without registration.
