AI Video Blur: Automatically Blur Faces & Moving Objects

Automatically detect faces or select license plates, screens, labels, and other moving objects to blur. AI keeps the blur aligned as targets move, while your sensitive footage stays in a desktop workflow—no need to upload unblurred source videos to a third-party online blur tool.

  • Automatically detect and blur one, multiple, or all faces
  • Track selected license plates, screens, logos, labels, and moving objects
  • Blur sensitive videos locally on your desktop before sharing or publishing
Available on:

For Windows 11/10/8/7

For macOS 10.13 or later

One Tool, Multiple Privacy Tasks

Blur What You Need in Any Video

Handle common privacy and censorship tasks—from face blur and license plate blur to moving-object tracking, video background blur, and sensitive-information masking.

Face Blur

Automatically detect faces and blur selected people or all detected faces.

License Plate Blur

Select a plate once and let AI keep the blur on it as the vehicle moves.

Video Background Blur

Keep the subject clear while blurring private or distracting surroundings.

Moving Object Blur

Track and blur selected logos, screens, labels, badges, or other targets.

Censor & Pixelate Video

Use mosaic, pixel, soft blur, or stickers to censor faces and details.

Sensitive Information Blur

Hide usernames, emails, API keys, addresses, documents, and screen data.

Core Advantages

AI Video Blur Without Tedious Frame-by-Frame Editing

Use AI where it saves the most time, then keep control over which people or details are hidden, how strong the blur looks, and what happens before export.

Automatically Blur Faces in Video

Import your footage and let AI scan the video for faces. Review detected face thumbnails, select a specific person, or blur every detected face at once.

  • Blur one person, multiple people, or all detected faces.
  • Keep face blur attached as people move through the scene.
  • Useful for bystanders, children, interviewees, customers, and employees.

Track and Blur Any Selected Moving Object

Draw a box around a license plate, logo, screen, username, document, label, address, badge, or another target. UniConverter tracks the selected object and keeps the blur aligned as it moves.

  • No frame-by-frame repositioning for tracked targets.
  • Works for moving and stationary sensitive details.
  • Preview the tracking result before export.

Blur Multiple Videos in One Batch Workflow (Coming Soon in V18)

Add several videos, switch between clips to review targets and settings, then process and export them without rebuilding the same workflow from scratch.

  • Ideal for vlog batches, social clips, dashcam footage, classes, interviews, and training videos.
  • Review each file before processing the full queue.
  • Reduce repetitive import, setup, and export steps.

Choose How Your Video Gets Blurred

More control than a basic blur filter. Control how strongly each target is hidden and how naturally the blur blends into the frame. Switch between mosaic, soft blur, pixel, and sticker effects, then refine the result before export.

  • Adjust blur strength for lighter masking or stronger anonymization.
  • Use feather controls to soften the edges of the blurred area.
  • Change opacity and blur style to match privacy or creative needs.
