How to blur a face in Premiere Pro (and a quicker way)
The Premiere Pro steps to mask and track a blur onto a face, plus a free way to blur every face with no tracking.
Premiere Pro has proper tools for this: you apply a blur effect, draw a mask around the face and let Premiere track the mask along the clip. It works well, but it needs Premiere, a bit of setup per face, and a render. Here are the steps, and above, a browser tool that tracks and blurs every face for you in one pass.
Premiere’s mask tracking is good, but it is still per-face setup. The tool above needs none.
“Gaussian Blur has no mask option”, here’s the fix
A common snag: people open the Gaussian Blur settings looking for a mask and don’t find one. The mask isn’t on the filter, it’s in the Effect Controls panel. Apply the blur to the clip, then in Effect Controls click the small ellipse or pen icon under that effect and draw the mask over the face. That mask is what you then track along the clip.
How to blur a face in Premiere Pro, step by step
- Drop your clip on the timeline and open the Effects panel.
- Search for Gaussian Blur (or Mosaic) and drag it onto the clip.
- In Effect Controls, click the ellipse mask on that effect and draw it over the face.
- Raise the Blurriness, and turn on Repeat Edge Pixels so edges stay clean.
- Use Track Mask Forward so the mask follows the face along the clip.
- Review the track, fix any drift, then export.
When the tool above is quicker
If your whole job is hiding faces, opening Premiere, masking each face and tracking it is a lot of overhead. The Video tab above detects and blurs every face automatically, which is faster for quick anonymization, group shots, or when you do not have Premiere on hand.
Privacy note
Premiere works on files on your machine, which is good for privacy. The browser tool here keeps the same benefit: your footage is processed on your device and never uploaded to a server.
How to blur any object in Premiere Pro, not just a face
The same masking workflow you use on a face works on anything else in a shot, a license plate, a laptop screen, a tattoo, a logo on a shirt, or a piece of paper with private information on it. Apply Gaussian Blur to the clip, open Effect Controls, and draw a mask shaped to that object instead of a face, an ellipse for round or rectangular items and a free draw bezier for irregular shapes.
Set the blur Amount high enough that the object is unreadable, then check Track Mask Forward so the mask follows the object as the camera or the item moves. For small, fast moving objects like a phone screen or a badge, keep the mask a little larger than the object so tracking drift does not expose an edge.
How to add and feather a blur mask cleanly
- Select the clip, apply Gaussian Blur from Video Effects, then click the effect name in Effect Controls so its on screen controls appear.
- Choose the ellipse or free draw bezier mask tool from the small icons under the effect name, and draw the shape directly over the area you want hidden.
- Open Mask Path and set Mask Feather to soften the edge, usually 15 to 30 for a face sized area, so the blur blends instead of showing a hard circle.
- Raise Mask Expansion slightly if the mask needs to cover a bit more than you drew, which helps hide edges during motion.
- Lower Mask Opacity only if you want a partial effect, for full anonymity leave it at 100 percent.
Fixing a mask that drifts off the subject while tracking
Premiere's built in tracker can lose the subject during fast movement, a turn of the head, or a change in lighting, which lets part of the face show through. When this happens, scrub back to the last good frame, adjust the mask position there, and click Track Mask Forward again so tracking restarts from a correct point instead of compounding the error.
For a clip with a hard cut or a big lighting change partway through, split the clip at that point in the Timeline and track each half separately, since one continuous track across a cut usually fails. If drift keeps happening in one section, add manual keyframes to the mask path every few frames in that section instead of relying on tracking alone.
Blurring the same face or object across several clips
Retracking a mask on every single clip is slow if the same person or object needs to be hidden throughout a sequence. Create an adjustment layer, place it on a track above your clips, and apply Gaussian Blur with a mask to the adjustment layer instead, then track that one mask across the clips underneath as long as the framing stays reasonably consistent.
For clips with different angles or cuts, select the clips in the Timeline, right click, and choose Nest to combine them into a single nested sequence, then apply the blur and mask once to the nested clip. This still needs the mask retracked at each cut, but it keeps the effect and its settings in one place instead of duplicated across every clip.
How strong the blur needs to be for real anonymity
A light Gaussian Blur can still leave enough shape and contrast for someone to recognize a face, especially in HD or 4K footage. Push the Amount well past the point where features blur into a soft blob, typically 60 to 100 or higher depending on how large the face is in frame, and zoom in on the exported video to confirm no eyes, nose, or mouth are still readable.
Mosaic or pixelate style effects can work as an alternative to Gaussian Blur when you want a visibly obvious privacy effect rather than a soft one, and both need the same masking and tracking steps described above. When in doubt, err on the side of a stronger blur, since a face that is still faintly recognizable defeats the purpose.
This works the same way across recent Premiere Pro versions
The Effect Controls mask tools, Track Mask Forward, Mask Feather, and Mask Expansion have stayed in the same place through recent Premiere Pro releases, so the steps above apply whether you are on an older CC version or the current one. Panel layouts and icons get small visual refreshes between versions, but the underlying masking and tracking workflow has not changed.
If you would rather skip manual masking and tracking altogether, blurfacephotos.com detects and tracks every face in a photo or video automatically in the browser, with nothing uploaded, which is worth trying first for straightforward face blurring jobs.

Tips and common mistakes
- Turn on Repeat Edge Pixels on the blur so the mask edges don’t show a hard line.
- After Track Mask Forward, scrub back through the clip and fix any frames where the mask drifted off the face.
- Feather the mask a few pixels for a natural edge, but not so much that the face peeks out.
- A common mistake: tracking one face and forgetting a second person in the background, add a masked blur for each.
- For a quick job or a group shot, the automatic tool above is faster than setting up and tracking each mask.

Frequently asked questions
How do you blur a face in Premiere Pro?
Apply a Gaussian Blur (or Mosaic) to the clip, draw an ellipse mask on the effect over the face, raise the blur, then use Track Mask Forward so it follows the face, and export.
Does Premiere track the face automatically?
Premiere tracks the mask you draw, so it follows the face once you set it up per face. The tool on this page detects and tracks faces for you with no setup.
How do I blur multiple faces in Premiere?
You add a separate masked blur and track for each face. The editor above hides up to five faces at once automatically.
Can I blur a face in a video without Premiere?
Yes. The Video tab above blurs every face across your clip free, in your browser, with no editing software.
What format does the browser tool export?
An anonymized WebM (video only, no audio), created entirely on your device.
Why does Gaussian Blur have no mask option in Premiere?
The mask lives in the Effect Controls panel, not the filter dialog. Add the blur to the clip, then click the ellipse or pen icon under the effect in Effect Controls to draw and track a mask over the face.
How do I blur a moving object in Premiere Pro?
The same way as a face: apply a blur, mask the object in Effect Controls, then use Track Mask Forward so the mask follows it along the clip.
How do I blur a face in Premiere Pro on Mac?
Exactly as on Windows, apply Gaussian Blur, mask it in Effect Controls, track the mask, and export. The steps are identical on Mac and PC.
How do I blur an object in Premiere Pro that isn't a face, like a license plate or a screen?
Apply Gaussian Blur to the clip, open Effect Controls, and draw a mask over the object using the ellipse tool for round or rectangular shapes or the free draw bezier tool for irregular ones. Raise the blur Amount until the object is unreadable, then enable Track Mask Forward so the mask follows the object through the shot, checking every few seconds for drift since small objects can be harder to track than a face.
How do I add a blur mask in Premiere Pro?
Apply the Gaussian Blur effect to a clip, click its name in Effect Controls to reveal the on screen mask icons, and choose either the ellipse or the free draw bezier tool, then draw the shape over the area to hide. Adjust Mask Feather so the edge blends smoothly and Mask Expansion if the shape needs to cover slightly more area, and turn on Track Mask Forward so the mask moves with the subject instead of staying fixed in place.
What does a Gaussian blur mask do in Premiere Pro, and how strong should it be?
A Gaussian blur mask limits the blur effect to a specific shape you draw, like a face or an object, instead of blurring the whole frame, and it can be tracked so that shape follows movement across the clip. For real anonymity the blur Amount needs to be high enough that facial features are completely indistinct, often 60 or higher depending on how large the face appears, since a light blur can still leave someone recognizable.
