Three ways to censor
Censoring an image means hiding the parts you don't want others to see. This tool gives you all three common methods in one place: a soft blur, a block mosaic (pixelate), and a solid bar (redact). Pick whichever fits — and mix areas freely across a single image.
Drag a box over each thing to censor — a face, a home address, a card number, a chat name. The pixelate default gives the familiar 'censored' mosaic, but you can switch any time. Everything outside your boxes stays sharp and full-resolution.
How to censor an image
- Open your image. Drag it onto the tool, choose a file, or paste it.
- Select what to hide. Drag a box over each sensitive area. Add as many as you need.
- Choose a style and download. Pick blur, pixelate, or a solid bar, then download in your original format.
Use a solid bar for the truly secret
Blur and pixelation can occasionally be partly reversed at light settings. For anything that must never be read — a password, a signature — use the Redact bar, which paints solid pixels over the area.
censor image的原理
- 它的作用
- 模糊、像素化或纯色条——任你选择
- 工具如何实现
- 三种遮盖方法都在同一个编辑器中：多次模糊、分块马赛克和纯色条；你可以在同一张图像的不同方框上应用不同方法，而方框之外的一切都保持清晰。
- 用途
- 打码用于隐藏截图或照片中你不想分享的部分——一张脸、家庭住址、卡号、聊天名称——同时让图像其余部分保持完好。
- 能否还原？
- 模糊和像素化是对像素取平均，在轻度设置下可被部分还原，而纯色条（涂黑）会覆盖像素、不留下任何可重建的内容——对任何绝不能被读到的内容请选用色条。
提示： 按风险匹配方法：密码或签名之类的秘密用色条，而更看重自然观感的人脸和背景用模糊或马赛克。

常见问题
What's the best way to censor a phone number or address?
Use the Redact (solid bar) mode. It paints over the pixels completely, so the text can't be reconstructed — unlike a light blur or pixelation.
Can I censor several things at once?
Yes. Drag a box over each item; every box is censored independently, and you can mix areas across the same image.
Does censoring change the rest of the photo?
No. Only your selected areas are altered; the rest stays at full resolution. The result is baked into the downloaded file.
Where is my image processed?
The blurring happens in your browser, so the new file is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
