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.

What should I check before sharing a redacted screenshot?

Open the saved file again and look at the whole frame, not only the field you meant to cover: tab titles, the URL bar, avatars, timestamps, taskbar notifications and anything reflected in a second window.

Does it work with screenshots from my phone?

Yes. An iPhone or Android screenshot is an ordinary image and is treated the same way. Draw each box a little larger than the text, because on a small screen it is easy to leave a character showing.

A screenshot is the fastest way to explain a problem and the easiest way to leak something: the support ticket with your account number in it, the invoice shared in a group chat, the bug report that includes a customer's email, the bank app capture posted to ask whether a charge is normal. Before any of those leave your device, the private parts need to be gone, not just hidden.

On this page you draw a box over each item and choose a solid black bar or pixelation. The exported file has those pixels replaced, so there is no layer to peel back and no original underneath, which is the failure that has embarrassed companies and courts releasing documents with a black rectangle drawn on top. For text, which is what screenshots are mostly made of, the solid bar is the safer choice: coarse pixelation of a known font can sometimes be reconstructed, a black block cannot.

What the tool does not do is find the sensitive parts for you. You decide what gets covered, so before exporting, look past the obvious field: browser tab titles, the address bar, a username in a corner, notification pop-ups, an order number in the footer. The screenshot is edited on your device and never uploaded, which means the unredacted version exists only on your own screen.
