Image Censor Tool: Pixelate, Blur, or Black Out Sensitive Areas
Hide faces, license plates, addresses, or confidential details in an image. Choose pixelation, blur, or a solid black fill. Everything runs locally in your browser, so your image is not uploaded.
Three ways to censor an image
Pixelation creates visible mosaic blocks, blur softens details, and black fill completely covers the selected area. Draw as many censor regions as needed, then download the edited PNG.
Frequently asked questions
How can I make areas in an image unreadable?
Load an image, choose Pixelate, Blur or Black out and draw a rectangle over the area with your mouse or finger. You can mark as many areas as you like.
Which censoring method is the safest?
For text passages and personal data, a solid black fill is the safest because nothing remains recognizable. For faces and license plates, pixelation works particularly well.
What is the difference between pixelation and blur?
Pixelation breaks the area into coarse blocks, a mosaic effect. Blur makes the details blurry while the color gradient stays intact, so the area is less noticeable.
Can I undo a mistake?
Yes. Undo removes the last step, while Reset clears all marked areas and lets you start over.
Which block size should I choose?
For small details such as a single face or a license plate, a block size of 12 to 16 pixels is often enough. For large areas a bigger block size works best.
Are my images uploaded?
No. Everything runs locally in your browser, your images never leave your device and are not stored anywhere.
