When creating a video in a public space, you may capture people who don’t want their faces to be on video. With AI blur effects, you can now effortlessly blur someone’s face without having to use complex editing techniques. You can protect someone’s identity right from your phone by using cutting-edge blur effects for both photos and videos. In this post, we explore the best editing app for blurring faces and explain how to use the face blur effect in your own videos.

Why Use the Blur Face Effect?

The face blur feature works by placing an overlay over a subject’s face that jumbles the pixels to create a hazy, blurry look. This way, their face is no longer recognizable. Blurring people’s faces allows you to post your videos online without revealing the identities of people who may not want to be filmed. You can also use it to enhance your videos with special effects. Here are some of the main reasons to consider using face blur for the videos you post online:

  • Respecting others’ privacy: When filming a video in a public space, you may capture people who don’t want you to use their image in a video. If you can’t get their consent to appear on video, you can simply blur their faces to avoid any privacy concerns. Prank videos, street interviews, and other videos filmed in public spaces can all benefit from face blurring.
  • Protecting someone’s anonymity: Someone may specifically want to protect their privacy while participating in a video. For example, people interviewing for documentary videos may want to share their experiences while remaining anonymous.
  • Adding visual effects to a video: Blurring and unblurring faces can also be a cool special effect. If you want a dramatic face reveal in your video, the blur feature can be a good option. You can also use it to create a fun visual effect for subjects in a music video, short film, or other project.

Regardless of why you want to use the blur filter, it’s a useful feature that can help you create quality content.

PowerDirector — The Best Blur Face Video Editing App

Available on: iOS and Android

PowerDirector is an all-in-one free video editing app that offers a high-tech solution for your face-blurring needs. Because PowerDirector uses AI to enhance its face blur feature, you can accurately blur the faces of moving subjects. It also gives you the option to refine and adjust the blur settings, allowing you to create a video that matches your vision.


You can use the Auto blur mode to automatically obscure the faces in your video. In Auto mode, the blur effect tracks the faces of your target subjects so their face will stay blurry regardless of how much they move in the video. You can also select which parts of a person to blur, from their face to their entire body.


If you want to adjust the hidden area to your specifications, you can also use the Manual mode. In Manual mode, you can adjust the shape and size of the mosaic effect that creates the blurred look. You can also blur other areas in the video if you want to hide multiple faces. With the Reversal button, you can even blur the background instead of people’s faces and fine-tune the intensity of the blur.

How To Blur Face in Video on iPhone and Android

You can use the best blur video app – PowerDirector – to blur faces directly from your phone. Here are the basic steps to follow to get started with this useful feature:

1. Download PowerDirector: The Best Blur Face App

Start by downloading the PowerDirector mobile app on your iPhone or Android device. It includes a powerful face blur feature that can help you hide people’s faces in your videos, protecting their identities with a professional-quality effect. Open your device’s app marketplace, search for the PowerDirector app, and download it to your phone.

Whether you want to blur a single face or a whole crowd of people, PowerDirector can handle it. And once you download PowerDirector, you can use it for all your video editing needs.

2. Tap “Mosaic” and Import Your Video


The Mosaic feature in PowerDirector is the best way to blur faces or objects in your video. It adds a jumbled pattern over the area you want to hide, resulting in an impressive blur effect. Click on “Mosaic” to start using this feature, then import the video you want to edit.

3. Select the Way To Add the Mosaic


Decide whether you want to use the Auto or Manual method to blur your video. The Auto method automatically detects people and faces in your video to blur. With the Manual feature, you'll need to select the area you want to hide. However, you can select anywhere in the video when using the Manual feature, which means you can blur more than just faces and people.

4. Make Adjustments

Start blurring the faces in your video by using the Mosaic tool and making adjustments as needed. Here’s how to get started with each of the available options:

  • Auto
  • PowerDirector

    If you only want to blur faces or bodies in your video, the Auto feature is a quick, convenient way to get started. It uses AI to identify the subjects and track their movement automatically. Follow these steps to use the automatic blur:

    1. Select the people you want to blur: Tap on the people you want to target with the blur feature.
    2. Select to blur face or body: The Auto option allows you to blur someone’s face or their whole body. Choose the option you prefer for your video.
    3. Adjust Strength and Feather: You can change the look of the blurred mosaic by adjusting the strength of the filter. You can also add a feathered effect and adjust the intensity to smooth out the edges.
  • Manual Tracking
  • PowerDirector

    You can also get more control over the areas you want to blur by activating the Manual mode. Here’s how:

    1. Select a Mosaic shape: Manually select the area you want to add a mosaic blur to.
    2. Adjust the size and placement: Next, refine the area by adjusting the size and placement of the shape.
    3. Adjust Strength and Feather: Just as with the automatic option, you can change the strength and feathering effect of the mosaic.
    4. Tap “Tracking”: Click on the Tracking feature to ensure the blurred area will move along with the subject.
    5. Add another mosaic or retrack if needed: After you preview the finished effect, you can change the tracking to make it more accurate. If you want to blur other areas in the video, simply add a new mosaic and repeat the steps.

5. Save Your Edits

When you’re happy with your changes, save the video. If you’re ready to share your finished video, click the “Export” icon on the top right. This will let you save the edited video to your device and upload it to other platforms. However, you can also save the blur effect and keep editing. Click the “Full Editor” option to explore the PowerDirector app and use its other fun features.
