How to Blur Faces on iPhone: Photos and Videos (2026)

Open a photo in the iPhone Photos app and look for a blur button. You won't find one. So if you're wondering how to blur faces on iPhone without installing anything, the honest answer is that you have three workarounds for photos: cover the face with a filled shape in Markup, brush over it with Clean Up (which can pixelate faces on newer iPhones) or crop the person out. Video is thinner still. Photos can crop a clip, and the nearest thing to a face cover is an overlay in iMovie.

Each of these gets the job done. None of them is quick, and on video they stop working the moment the person moves. I'll walk through the built-in steps first, then a faster route that runs in your browser with no app and no upload.

Key takeaways

Markup in iPhone Photos has no blur or pixelate tool. What it can do is put a filled shape at full opacity over a face.
On Apple Intelligence iPhones, brushing over a face with Clean Up may pixelate it instead of erasing it. You get no say in how strong that effect is.
Photos can't blur a face in a video. iMovie can put a still overlay on top of a clip, but the overlay won't follow a moving face.
DataBlur's free browser tools handle both cases: blur faces in a photo or blur faces in a video. Nothing gets uploaded.
A light blur is rarely enough. Use heavy pixelation or a solid box, and strip the location before you share.

How to blur faces on iPhone in a photo

Option 1: Cover the face with Markup (any iPhone)

Markup can't blur anything. It can, however, drop an opaque shape on top of a face. Apple's guide to Markup on iPhone covers text, shapes, stickers and drawing tools, and shapes come with fill color and opacity settings. Blur and pixelate aren't on the list.

Open the photo in Photos and tap Edit.
Tap the Markup button.
Tap the Add button, then Add Shape and pick a rectangle or a circle.
Drag the shape over the face. Pull the dots on its outline to resize it.
In the Markup toolbar, choose a solid fill color and set opacity to full.
Tap Done to save.

A thick black pen stroke works too. The filled shape is faster, though, and it doesn't leave gaps around the edges.

Option 2: Pixelate with Clean Up (Apple Intelligence iPhones)

Clean Up exists to remove distracting objects, and it only runs on iPhones that support Apple Intelligence (iPhone 15 Pro, iPhone 15 Pro Max or an iPhone 16 model or later). There's a side effect worth knowing about. Apple's Photos guide for Mac says that if you brush over a person's face, it "may become blurred with a pixelated effect". Users report the same thing on iPhone.

Open the photo in Photos and tap Edit.
Tap Clean Up. On iOS 27, Apple's iPhone guide puts it under Tools.
Brush over the face.
Check the result, then tap Done.

Notice the word "may" in Apple's wording. You can't pick the strength or the style, and the outcome depends on how much of the frame the face fills. Zoom in afterward and make sure the face is really pixelated, not just smoothed over.

Option 3: Crop the person out

When someone stands near the edge of the frame, cropping is the tidiest fix. Tap Edit, then Crop and drag the corners in until they're gone. It works on photos and videos alike. It just can't help with a face in the middle of the shot.

Where the built-in tools break down

Group photos. Covering 15 faces one shape at a time is slow, and the kid in the back row is the one you'll miss.
No real blur. You get a solid shape or a pixelation you can't adjust. A soft blur isn't on the menu.
Device limits. Clean Up needs an Apple Intelligence iPhone, and it isn't offered in every language or region.

The faster way: blur faces in Safari

The DataBlur face blur tool is a free web page, so on an iPhone you open it in Safari instead of installing an app. There's no sign-up and no watermark, and the photo isn't uploaded anywhere.

Open the tool in Safari.
Pick the photo from your library.
Blur the faces and save the result back to Photos.

On a group shot, that saves you from drawing a shape over every single face.

How to blur a face in a video on iPhone

What the Photos app can do

Not much. Clean Up and Markup are photo tools. For a video, Photos gives you trimming, light and color adjustments, filters and crop, which leaves cropping the person out as the only built-in fix.

The iMovie workaround

iMovie is free from Apple, and Apple's iMovie guides don't list a blur or pixelate effect you can put on a face. What iMovie does have is a picture-in-picture overlay, explained in Apple's iMovie guide. That lets you lay a solid image over the face.

Make a plain black image first. Covering the lens with your finger and taking a photo is enough.
In iMovie, open a movie project that contains your clip.
Move the playhead to the point where the face first shows up.
Tap the Add Media button, choose Photos and pick the black image.
Tap the More button, then Picture in Picture.
Select the overlay, tap the Position Control button, then drag and pinch it over the face.
Adjust how long the overlay stays on screen so it covers the stretch you need, then export the video.

One thing to watch: iMovie adds a Ken Burns zoom to photos you put in a project. If your black square starts drifting or growing, check its Ken Burns setting and switch it off.

Where it breaks down

The overlay doesn't move. Apple's guide describes no way to make it follow a person, so a face that moves needs a fresh overlay for every spot it ends up in. Thirty seconds of someone walking can mean a dozen overlays. Add a second person and you've doubled it.

The faster way: blur faces in a video in Safari

The DataBlur video blur tool tracks faces through a clip of up to 3 minutes.

Open the tool in Safari and pick the video.
Let it find the faces and follow them through the clip.
Untick anyone who should stay visible. You, for example.
Download the MP4. The original sound comes with it.

It runs in Chrome, Edge and recent versions of Safari, so if Safari on your iPhone is out of date, update iOS first. Like the photo tool, it keeps the clip on your phone.

How strong should the blur be?

Stronger than looks good. A light blur makes a face look private without actually hiding it, and people who know the person often recognize them anyway from face shape, hair and posture.

Text shows how weak light blur really is. In our blur-recovery study, light blur on text was recovered exactly in 92–100% of cases, and even 4-pixel pixelation was recovered 71% of the time. That study was about text, not faces, but the lesson carries over: a gentle blur is decoration, not privacy.

For faces, pick one of these:

Heavy pixelation, with blocks so large that no feature of the face survives.
A solid box, which takes the face out of the image entirely.

Blurring screenshots rather than photos? Same rule. Our guide on how to blur a screenshot covers that case.

What to check before you share

The face is only one clue. Before you post, scan the whole frame:

Name tags, school logos and team jerseys. Box them out too.
Tattoos, distinctive hair or clothing. Friends and family spot these before anything else.
House numbers, street signs and license plates. They lead straight to where someone lives.
Screens and documents in the background. Zoom in. Text that looks like a smudge on the phone is often readable at full size.
Location data in the file. iPhone photos and videos can carry the GPS coordinates of where they were taken.

For that last one, Apple's location metadata guide has a built-in fix. In the share sheet, tap Options and switch off Location. You'll see "Location Not Included" above the Options button.

That removes location only, and only when you share from Photos. To strip GPS, device and date details in one pass, use the free tools to remove photo metadata or remove video metadata. They run in the browser and don't upload the file either.

What this does not do

Here are the limits, for Apple's methods and for ours:

Automatic detection can miss faces. Faces seen in profile or partly covered are the usual misses. Check the result at full size before you share it.
A blurred face doesn't make someone anonymous. Voice, clothing, location and context can still give a person away.
It can't recall copies already sent. If the unblurred original went out, a blurred version doesn't replace it.
The video tool stops at 3 minutes. Trim longer clips first.
Light blur isn't protection. Use heavy pixelation or a solid box for anything sensitive.

FAQ

Can you blur a face on iPhone without an app?

Yes. In Photos, cover the face with a filled shape at full opacity in Markup, or brush over it with Clean Up on an Apple Intelligence iPhone. If you'd rather not draw over each face, the free DataBlur face blur tool runs in the browser with nothing to install.

Does the iPhone Photos app have a blur tool?

No. Markup gives you pens, text, shapes and stickers, but nothing that blurs or pixelates. The nearest built-in effect is Clean Up, which may pixelate a face you brush over. That requires an Apple Intelligence iPhone: iPhone 15 Pro, 15 Pro Max or an iPhone 16 or later.

How do I blur a face in a video on iPhone?

Photos can't blur part of a video. In iMovie you can put a black picture-in-picture overlay over the face, but it won't move with the person. The DataBlur video tool tracks faces in clips up to 3 minutes in recent Safari and gives you an MP4 with the sound intact.

Is blurring a face enough to make someone anonymous?

Not always. People who know the person can often see through a light blur. Use heavy pixelation or a solid box, and cover name tags, tattoos, house numbers and anything else that points to who they are.

Are my photos uploaded when I use DataBlur's tools?

No. The face blur, video blur and metadata tools run in your browser, so the photo or video stays on your iPhone. There's no sign-up and no watermark on the result.

How do I remove the location from a photo before sharing it?

In the iPhone share sheet, tap Options and turn off Location before you send. To remove GPS, device and date details from the file itself, use the free remove photo metadata or remove video metadata tool in the browser.
