Is the video uploaded to blur faces?

No. The linked face-blur workflow uses browser-local processing for the selected video. Your source remains on your device during the normal workflow.

Will it blur every face automatically?

Not always. Small, hidden, turned-away, or fast-moving faces can be difficult to detect, so review the preview and exported video before sharing.

Can it blur license plates or any private object?

This workflow is designed for faces. Use the linked region blur or pixelation tools when you need to cover another object or area.

Video privacy

Blur Faces in a Video Online

Protect people’s identities before sharing a clip by detecting faces in the browser, reviewing the preview, and exporting a blurred MP4.

Protect faces before you share a video

Face blurring is a privacy step, not a guarantee that every private detail has disappeared. Review the detection preview and the downloaded result carefully, especially when faces move, turn away, or appear briefly.

Use the preview to check what was detected

The browser face detector highlights the faces it can identify in the selected video. Use the preview to notice missed detections, small or distant faces, and moments where a person enters the frame before you commit to an export.

Preview the beginning, middle, and busiest sections of the clip.
Look for faces that are small, turned away, partly hidden, or briefly visible.
Do not publish sensitive footage until the exported result has been reviewed.

Choose a strength that survives playback and export

A blur that looks sufficient on a small preview may reveal details when the video is enlarged or paused. Increase the strength when the subject is close to the camera, then inspect the downloaded MP4 at the size and speed where other people will see it.

Use a stronger blur for close-up faces or high-resolution footage.
Review fast cuts and camera movement rather than only a still frame.
Use Pixelate Video or Blur Video when you need a broader manual privacy edit.

How it works

Three steps to finish the browser workflow.

1
Choose the video
Open the face blur tool and select the clip that contains the people you want to protect.
2
Review detection and strength
Let the browser detect faces, inspect the preview, and adjust the blur strength for the footage.
3
Export and inspect the MP4
Process the video, download the result, and review the complete clip before sharing it.
