Black box for sensitive text

A low blur strength can leave shapes that a reader can recognize, and short text can be guessed through a blur or pixels. A black box leaves nothing to read.

Need to find faces?

This tool hides only what you mark. To find faces automatically, use Face Blur.

How to blur part of a picture

  1. Add an image. Drop it on the page, paste it, or click "Choose an image".
  2. Drag a box over each area that you want to hide. To remove a box, click it.
  3. Choose a style: Blur, Pixelate or Black box. For Blur and Pixelate, set the strength.
  4. Check the result. Press "Hold to see original" to compare.
  5. Download the new image.

Which style should I use?

Use Black box for names, numbers, addresses and other sensitive text. It replaces the area with solid black, so the download keeps nothing from that area except the size of the box.

Use Blur or Pixelate when you only want to make an area less clear, such as a messy background or a logo. These styles do not keep the original pixels, but they do keep some information. A low blur strength can leave shapes that a reader can recognize. Short text can also be guessed: someone who knows the font can apply the same effect to likely text and compare the results.

What the tool does not do

The tool loads no AI model and looks for nothing in your image. It hides only the areas that you mark, so look at the whole image before you share it. To find faces automatically, use Face Blur. To remove metadata and keep every pixel, use the Metadata Stripper.

Is my image safe?

Your file stays on your device or secure network and never touches our servers. The download is a new flat image, with no layers and none of the original's metadata, such as GPS location, camera details and the embedded thumbnail. Read our privacy policy for what the page loads.

Frequently asked questions

Is my image uploaded to a server?

No. Your file stays on your device or secure network and never touches our servers. The page has no server code and loads no AI model. It loads its own code, Plausible analytics, and the example image if you choose it. None of these requests holds your file.

Can someone undo the blur or the pixels?

Not directly. The download is a new flat image that does not hold the original pixels of the box, so there is no layer to remove. For high-security work and sensitive text, choose Black box, because a blur or pixelate can leave shapes that a person can recognize.

Does the tool find faces or text for me?

No. It runs no detection and hides only the areas that you mark, so look at the whole image before you share it. For automatic face detection, use Face Blur.

Does the downloaded image keep its location data?

No. The download is a new file. It does not keep the original's metadata, such as GPS location, camera details, XMP data and the embedded thumbnail.

Do the other parts of the image change?

In an 8-bit sRGB PNG with no partial transparency, no: the visible pixels outside the boxes stay exactly the same. In other PNG files, the values can change: a 16-bit file becomes 8-bit, a gray file can change slightly in some browsers, another color profile is converted to sRGB, and partial transparency can change the colors. A JPG or WebP is compressed again when it is saved, so those pixels can change slightly. An image over 16 megapixels is made smaller first.

Which file types does it support?

JPG, PNG and WebP. The download has the same format as the original. If your browser cannot save that format, the download is a PNG.
