Can I censor more than one area?

Yes. Drag to add as many censor boxes as you like, undo the last one, or clear them all. Each box uses the currently selected style — black-out, blur, or pixelate.

Is a black bar truly permanent?

Yes. The bar is painted onto the pixels and the flattened image is exported, so the hidden area cannot be recovered from the downloaded file — unlike a layer you could toggle off.

Can I mix different censor styles in one image?

Each box uses the style selected when you draw it, but you can switch styles between boxes — for example a black bar over a number and a blur over a face — and they all flatten into the final image.

What happens if I make a mistake?

Use Undo last to remove the most recent box, or Clear to start over. Nothing is permanent until you download, so you can adjust the boxes freely beforehand.

Does the tool detect faces automatically?

No — you draw the areas yourself, which gives you full control over exactly what is hidden and avoids missing or over-covering content an automatic detector might get wrong.

Are the censored areas recoverable from the file?

For black bars, no — the pixels are replaced. Blur and pixelate alter the pixels too, but use a heavy setting or a black bar for anything truly sensitive to be safe.

How to use Image Censor Tool

Before sharing a screenshot, document photo, or group picture, you often need to hide just a few things: a face, a name, an account number, a license plate. This censor tool lets you draw boxes over exactly those areas and apply a black bar, a blur, or a pixelation to each. You can add as many boxes as you need, undo or clear them, and the effect is painted permanently onto the pixels when you download. Everything happens on a canvas in your browser, so the sensitive image you are protecting is never uploaded anywhere.

Drop an image onto the upload area or click to browse.
Pick a censor style: black-out, blur, or pixelate.
Drag on the image to draw a box over each area to hide.
Add more boxes, or undo and clear as needed.
Click Download Image to save the censored, flattened result.

Choosing a censor style

Each style offers a different balance of appearance and security. A black bar is the strongest and most obviously deliberate — the underlying pixels are completely replaced, so nothing can be recovered from the saved file. Blur softens an area into a frosted patch; it reads as less harsh but, if applied lightly, can occasionally be partially reversed, so use it generously over sensitive text. Pixelation breaks an area into blocks and sits between the two. For anything truly confidential — identity numbers, faces of vulnerable people — prefer a black bar or a heavy effect, and always confirm the result before sharing.

Style	Look	Security
Black-out	Solid bar	Highest — pixels replaced
Blur	Frosted patch	Moderate
Pixelate	Blocky squares	Moderate to high

Why flattened output matters

Some apps let you place a censor shape as a separate layer, which is risky: if the file keeps that layer, anyone can move or delete it to reveal what was underneath. This tool avoids that entirely by painting the effect directly onto the image pixels and exporting a single flattened PNG. There are no hidden layers, no recoverable original beneath a black bar, and no metadata describing what was covered. What you see in the downloaded file is exactly what others will see — which is the whole point of censoring. As a final check, reopen the saved image to confirm every sensitive area is covered before you send it.
