If you’re looking for a simple and effective way to blur, pixelate, or censor private areas of your photos and documents, I highly recommend using the Facepixelizer online tool.

Facepixelizer is a powerful image editing tool that is designed specifically for anonymizing images. With Facepixelizer, you can easily hide sensitive information in images that you want to keep private. This can include blurring out text or pixelating faces in your images.

One of the key advantages of using Facepixelizer is that it runs directly in your browser, meaning that your images never leave your device and are never transmitted over the network. This ensures that your images remain completely secure and private. Additionally, all processing takes place locally on your device, providing an added layer of security and peace of mind.

Facepixelizer is a versatile tool that is useful for a wide range of individuals and professions. Here are some examples of who might benefit from using Facepixelizer:

  • Tutorial creators who need to hide sensitive information (such as email addresses) in screenshots
  • Bloggers who want to use personal photos in their blogs without revealing identifying information
  • Photographers who want to protect themselves from potential lawsuits, such as in cases where they’ve captured an individual’s likeness without their consent
  • Journalists who need to protect the identity of people in their photos, such as in cases of whistleblowers or confidential sources
  • Facebook users who want to avoid negative consequences (such as losing their job) from posting photos that may be considered inappropriate or unprofessional
  • Parents who want to share photos of their children online while still maintaining their privacy
  • Anyone who needs to redact documents, such as employees who need to submit private financial statements for expense reimbursement purposes but want to obscure sensitive information.

Regardless of your specific needs, Facepixelizer offers a simple and effective way to obscure private information in photos and documents.

Easily blur, pixelate or censor private areas of your photos and documents

To get started, simply drag and drop a photo (in .jpg or .png format) onto the Facepixelizer website. Then, select the region of the image you want to blur or pixelate. Once you’re done, you can save your photo.

It’s worth noting that the tool also has an automatic face and text detection mode, which is quite useful.

Tutorial with images

  1. Drag a photo (.jpg or. png) onto the facepixelizer web page.
  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.

Auto Mode – Anonymization Tool

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.

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.
