What is Facepixelizer?

Facepixelizer is a specialized image editor for anonymizing images. Use Facepixelizer to quickly hide information in images that you don't want to become public. For example, you can blur out text and pixelate faces that appear in your images.

Even though Facepixelizer runs in the browser, your images are secure because they never leave your browser and are never sent over the network. All the processing happens in your browser.

How do you use it?

Easy as1-2-3

  2. Click and drag your mouse over any regions that need to be blurred or pixelated.
  3. Save your image.

Fast Workflow

The workflow in Facepixelizer is optimized for anonymizing images with the fewest clicks possible.

Facepixelizer requires only one click per anonymization. Compare that to over 7 clicks in Photoshop. Unlike many other editors, you do not need to first select an area and then apply an effect. The main reason Facepixelizer is so efficient is that you don't need to adjust the settings of the effect to apply, Facepixelizer figures it out for you.

Face Detection

Facepixelizer has face detection built in.

The face detection runs in the browser and it works quite well, but it may not catch all faces. For example faces that are tilted or faces that are looking to the side. However, it is quite easy to find and touch up those faces using the Anonymization Tool.

You can choose between having faces pixelated or blurred.

Face detection can be handy if there are a lot of faces in your image as in the following image.

Anonymization (Selection) Tool

The Anonymization tool (called Selection Effect in menu) has two modes: Auto and Manual.

Facepixelizer Selection Tool UI

Auto Mode - Anonymization Tool Automatic redacting tool: text in a big font is blurred more then text in small font.

Auto mode is intelligent and "knows" whether you are anonymizing text or a face. Images are pixelated while text is blurred. The amount of blurring or pixelation is dependent on the size of the area. If the area is large, the effect is scaled appropriately. In other words, the effect is scale-independent.

For text, the amount of blurring is scaled to match the font size, so that text in a large font is blurred more than text in a small font. Hence, the amount of blurring appears to be the same independent of the font size, saving you from having to adjust the settings for different font sizes.

Automatic redacting tool: Large faces are pixelated more than small faces.

Pixelation of faces is also scale-invariant, i.e. the amount of blurring is scaled to match the size of the area. Large faces are pixelated more than small faces.

Manual Mode - Anonymization Tool

If you are not happy with what auto mode gives you then you can switch to manual mode.

Facepixelizer Manual Mode UI

In manual mode you can choose between blur, pixelate and redact (i.e. solid black). Use the slider to change the amount or strength of the effect. The preview shows what the effect will look like.

To undo, you drag the mouse from the bottom right to the top left, i.e. in the opposite direction of when applying an effect. This is very efficient to use once you get used to it. If this is confusing, please watch the video.

Facepixelizer Undo Explanation

Undo can be used to get interesting effects such as to reveal one area of the image. In the image below, the whole image was first pixelized, and then the undo effect was applied to the eyes.
