Free options
Free ways to hide a face in an iPhone photo.
You don't always need an app. Here are the free tools already on your iPhone, what each one actually does, and when a dedicated face-blur app is worth it.
Short answer: for one or two faces, use Photos → Edit → Markup and draw a filled, fully opaque shape over each face. It's free on every iPhone. Apple Intelligence iPhones can also pixelate a face with Clean Up, and Signal can auto-blur faces in a photo you send. None of them removes location data from the file on its own, and none is quick for many faces or many photos.
1. Photos Markup: an opaque box (every iPhone)
- Open the photo in Photos, tap Edit, then the Markup (pen) button.
- In the Markup toolbar, tap the + button, then Add Shape, and pick a square or circle. Drag it over the face.
- Use the Markup toolbar to set a solid fill color at full opacity. Drag the dots to resize it past the hairline and jaw.
- Repeat for each face, then tap Done.
Good: free, built in, truly opaque. Limits: no face detection, no pixelate or blur, one shape at a time. The pen tool at low opacity is not a safe cover. And Photos keeps the edit reversible in your library (Revert), so share the edited version, not a backup of the original.
2. Clean Up: pixelate a face (Apple Intelligence iPhones)
Apple's iPhone User Guide for iOS 18 and iOS 26 says that in Clean Up, “if you brush over a person's face, the face may become blurred with a pixelated effect.” Open the photo → Edit → Clean Up, then brush over the face.
Limits: it needs a device that supports Apple Intelligence (iPhone 15 Pro, iPhone 15 Pro Max, iPhone 16 models, and later) on iOS 18.1 or later, with Apple Intelligence turned on. Apple says the face “may” be pixelated, not that it always will be. It's one face at a time, and pixelation can leave a face recognizable. We couldn't find the same sentence in Apple's iOS 27 guide, so check that it still happens on your version.
3. Signal's blur tool (when sending through Signal)
Signal's photo editor has a blur tool that can automatically blur faces and lets you brush over anything else. Signal says the processing happens on your device, and also that it doesn't detect every face every time. It's built for sending: to keep a copy, you can send it to Note to Self and save it from there.
Limits: it's a blur, not an opaque cover. It only works inside Signal, and saving a copy is a workaround rather than an export feature.
What about Snapseed or Instagram?
Snapseed is free and excellent, but it has no face blur or censor tool. Its Lens Blur is a background bokeh effect. Instagram, Facebook, and WhatsApp don't offer a face blur tool in their photo editors, so stickers are the usual workaround there. A sticker can often be moved or removed before posting, so make sure it's flattened into the image.
Don't forget the file itself
Covering a face doesn't remove the photo's GPS location. When sharing from Photos, tap Options at the top of the share sheet and turn off Location. More on location metadata.
When a dedicated app is worth it
If you regularly post photos with several kids, or share batches from parties, games, or school events, the free tools get slow: no face detection, one shape at a time, and a separate step for location. Blur Photo & Face Censor finds the faces, lets you tap which to cover, handles 1–20 photos at once, and exports a copy without location data. $3.99 once, no subscription. Other paid and free apps are compared in face blur apps compared.

Questions
Can I blur a face on iPhone without downloading an app?
Yes, with limits. Photos Markup can place an opaque filled shape over a face on any iPhone, and Clean Up may pixelate a face on Apple Intelligence iPhones. Neither detects faces for you.
Does Markup permanently hide the face?
In the exported or shared image, an opaque filled shape covers the face. In your own library, Photos keeps edits reversible, so the original is still available to you.
Does blurring a face remove the photo's location?
No. Location is metadata. Turn off Location in the share sheet Options, or use an app that exports a copy without it.
When free tools get tedious
Blur Photo & Face Censor works on your iPhone or iPad, exports a new copy without location data, and never uploads your photos. $3.99 once, no subscription.
