Is a black box safe, or can it be removed?

In this tool the pixels underneath are actually replaced, so the hidden info is gone for good — unlike a box added in some apps that can be peeled off.

Should I use blur or a solid box?

For truly sensitive data (numbers, emails), use the solid black box — blur can sometimes be partially reversed on low-detail text.

Sharing a screenshot of a chat, invoice or dashboard? Redact the sensitive bits — names, emails, card numbers, addresses — by dragging solid boxes over them. The information is permanently removed from the exported image, not just covered.

It all runs in your browser, which matters when the screenshot has private data.
