Short answer: the stock Photos app has no blur or pixelate tool — Markup only offers drawing tools (pen, highlighter, pencil, shapes), so the best it can do is scribble over a face. To actually blur one, open make-blur.com in Safari, upload the photo from your camera roll, tap Detect, and download. No App Store download, and the photo never leaves your phone.
Why the native Photos > Edit > Markup tool can't blur a face
Open a photo, tap Edit, then the Markup icon (the pen tip). What you get is a drawing toolkit — the same one you'd use to sign a PDF or circle something on a screenshot. Every tool in it puts marks on top of the photo. None of them process the pixels of the face itself, which is what a blur or a pixelation actually is.
| Markup tool | What it is | Can it hide a face? |
|---|---|---|
| Pen | Opaque freehand stroke | Only if you scribble it solid — looks like vandalism, and the edges still trace the head |
| Highlighter | Semi-transparent stroke (that's its whole point) | No — the face shows straight through it; this is the classic leaky redaction |
| Pencil | Textured, partly transparent stroke | No — same see-through problem as the highlighter |
| Shapes (□ ○) | Outline square / circle from the + menu | Only the outline; you'd have to fill it, and the fill opacity is a slider you can leave leaky |
| Magnifier / Loupe | Zooms into a region | The opposite — it enlarges the face |
| Text / Signature | Types text or drops a saved signature | No |
The trap most guides walk you into. They tell you to grab the highlighter and swipe over the face. But the highlighter is designed to be semi-transparent — that's the entire point of a highlighter — so the face is still perfectly visible underneath your yellow smear. Reach for the opaque pen instead and you can hide it, but now it looks like you took a marker to the photo, and the outline of the head still shows where you traced. Neither is a blur, and neither is something you'd want to post.
What about the “Clean Up” tool?
iOS 18.1 added a Clean Up eraser to Photos, but it's a different thing entirely: it removes an object and paints over the gap, rather than blurring anyone. It also requires an Apple Intelligence–capable iPhone (iPhone 15 Pro and up), so most phones don't have it at all. If your goal is “you can tell someone was here, but you can't tell who,” erasing them is the wrong tool — you want a blur or a black bar over the face, which is exactly what's missing from Photos.
Blur a face on iPhone in Safari, step by step
This runs entirely on your phone. There's no upload, so there's no waiting on a progress bar and no copy of your photo sitting on someone's server.
- 1Open make-blur.com in SafariNo App Store trip, no 40 MB download, no account. Just the website. It works the same in Chrome for iOS, but Safari is what's already on the phone.
- 2Tap to upload, then pick Photo LibraryiOS offers Photo Library, Take Photo, or Choose File. Pick the photo from your camera roll. Safari hands the page a JPEG copy, so the HEIC format your iPhone shoots in is a non-issue.
- 3Tap DetectThe face model loads once (a couple of seconds the first time, then it's cached) and boxes every face it finds — including the small ones at the back of a group shot.
- 4Tap a face to keep it sharp, or draw over what was missedDetected faces are toggles: tap the one you want left alone, and the rest stay masked. For anything the detector skipped — a licence plate, a badge, a house number — drag a box over it by hand. A hand-drawn region masks exactly as well.
- 5Choose the style: blur, pixelate, black bar or emojiBlur or pixelate for cosmetic cover. Black bar or emoji when it actually has to hold — those overwrite the pixels instead of averaging them.
- 6Download, then Save Image back to PhotosThe file lands in Files → Downloads at full resolution. Open it, tap Share → Save Image, and it's back in your camera roll — as a new photo, with the original untouched. The export also carries no EXIF or GPS, because it's re-encoded from a canvas.
Live Photos and screenshots, before you share them
A Live Photo is really a still image plus a short video clip. You blur the still: share or export the Live Photo as a regular photo first (Share → the still is handed over as a JPEG), then run it through the tool like any other picture. The moving clip isn't what gets posted to a feed anyway — the frame is.
Screenshots are the simplest case of all. They're saved as PNGs, so there's no format friction — take the shot, upload it, mask the face, name or address, and download. This is the quickest way to scrub a chat screenshot or a map before it goes anywhere.
Nothing is uploaded — and why that matters here
The photo you're blurring is, by definition, one you'd rather not hand to a stranger's server. So it doesn't go to one. Detection and blurring both run on a canvas inside Safari, and the download is built on your phone. There is no endpoint on our side that accepts an image, which is easy to verify: load a photo, switch on Airplane Mode, and keep working — it all still runs.
For the GDPR that distinction is the whole ballgame. Processing on your device means no third party ever holds the picture, so there's no transfer to assess and no processor to trust. One caveat worth being straight about: blur and pixelation only average the pixels of a face, which counts as pseudonymisation rather than true anonymisation — the person can still be matched back. A black bar or an emoji overwrites the pixels outright and gets you to genuine anonymisation.
Also works for licence plates, and on iPad
The auto-detector finds faces, not plates — but you don't need it to. Drag a box over the plate by hand, pick a style, and download. Same two-second gesture you'd use for a face the detector missed.
Blur a licence plate →Identical website, identical flow, in Safari on iPadOS. The bigger canvas makes drawing regions by hand noticeably easier — handy when you're masking several faces or a fiddly plate.
FAQ
Is it free on iPhone?+
Yes. Blurring is unlimited, automatic face detection is free, and every masking style (blur, pixelate, black bar, emoji) is free. The free export writes a small make-blur.com wordmark into the bottom-right corner and caps files at 20 MB. Pro removes the wordmark and raises the cap to 60 MB. No App Store download, no signup to blur your first photo.
Does the free version put a watermark on my photo?+
A small wordmark in the corner, yes — the same trade the other free web tools make, stated up front so you know before you spend ten minutes masking faces. It does not stamp across the middle of the image, and Pro removes it entirely. Everything else — full-resolution export, all four styles, unlimited photos — is free.
Does it work offline in Safari?+
Almost entirely. The page and the face-detection model load over the network the first time (the model is a plain file download from a public CDN, carrying no image data). After that first load, you can turn on Airplane Mode and keep detecting, blurring, switching styles and exporting — because the work happens on your iPhone, not on a server. The very first detection needs a connection to fetch the model; nothing after it does.
My iPhone photos are HEIC — will the tool accept them?+
Yes, and you don't have to convert anything by hand. When you pick a photo through Safari's file picker on iOS, the system hands the web page a JPEG copy rather than the raw HEIC, so the upload just works. If you ever start from a file that is genuinely HEIC (say, one AirDropped as-is), export it as JPEG first — Photos does this automatically on share in most cases.
Where does the blurred photo go after I download it?+
On iOS, a download from Safari lands in Files → Downloads. To put it back in your camera roll, open it from there and tap Share → Save Image, or long-press the result in the tool and choose Add to Photos. It saves as a new image, so your original stays untouched.
Can I blur a face in a screenshot before sharing it?+
Yes, and screenshots are the easiest case — they're already PNGs, so there's no HEIC step at all. Take the screenshot, open make-blur.com in Safari, upload it from the camera roll, detect or draw over the face, and download. Handy for hiding a name, a face or an address in a screenshot of a chat, a map or a social post.
Does it work on iPad too?+
Yes — it's the same website in Safari on iPadOS, and the larger screen actually makes drawing regions by hand more comfortable. Same flow: open the site, upload, detect, mask, download.
Blur, black bar or emoji — which should I pick?+
If it's cosmetic (a stranger in the background of a nice photo), blur is fine. If a real person's safety, job or privacy depends on it, use the black bar or an emoji: those overwrite the pixels, so nothing is left to recover. Blur and pixelation only average the pixels, and enough of the face can survive to be matched back to a person.
