Blur part of image

Hide a face, licence plate or personal data with blur, pixelation or a black box.

How it works

  1. Drag an image into the box above or click to choose one from your device.
  2. Adjust the options on the right – the preview updates instantly.
  3. Click the download button and save the result.

Mark the area to hide and choose the method: blur, pixelate or a solid black box. For data that must stay unreadable, the black box is the safest choice.

Frequently asked questions

Are my images uploaded to a server?

No. Processing happens in your browser, on your device. The images never leave your computer or phone.

Is the tool free?

Yes. There is no sign-up, no limit on the number of images and no watermark on the result. The site is funded by ads.

Which image formats can I use?

JPG, PNG, WebP, GIF, BMP and, in recent browsers, AVIF. Convert iPhone HEIC photos to JPG on the phone first.

Is there a size limit?

We set no limit. Very large images (over 40 megapixels) may be slow or fail on phones with little memory.
