How to blur a face in Google Photos
The Blur option in Google Photos softens the background behind a Portrait-mode subject — it isn't built to hide a face. Markup, drawn by hand, is the actual workaround.
How to cover a face in Google Photos
This uses Markup, the freehand drawing tool, since there's no dedicated face-redaction feature.
- Open the photo and tap Edit.
- Tap the Markup icon — the pen symbol in the editing toolbar. This opens the drawing tools: pen, highlighter and, on some app versions, a blur brush.
- Pinch to zoom in on the face first. A tighter view makes it much easier to follow the edge of the face rather than drawing a rough oval around it.
- Pick a thick pen in a solid colour, or the blur brush if your version has one, and draw directly over the face. A solid stroke covers it completely; the blur brush, where it's available, softens it instead of blocking it out.
- Zoom back out and check the whole photo before saving — it's easy to leave a gap at the hairline or jaw when you were zoomed in close.
- Save as a copy. Google Photos keeps Markup edits as a new file, so the original stays untouched in your library.
Where this breaks down
The Blur adjustment that Google Photos advertises only shows up on photos taken in Portrait mode, and it works on the background depth map, not on a specific person's face — turning it up blurs everything behind the subject, which is the opposite of what you want if the subject is who you're trying to hide.
Markup is the actual tool for covering a face, but it's entirely manual: there's no face detection, so every face in a photo gets its own freehand stroke, checked and re-drawn if it doesn't fully cover the edges. A group photo with six faces is six separate passes.
It's also photo-only. Google Photos' video editor has trimming, filters and basic stabilisation, but no Markup and no way to draw over or blur any part of a frame — a face in a video can't be covered inside the app at all.
There's a metadata wrinkle too. Google Photos syncs originals to your account by default, so a photo containing a face you're trying to protect may already be backed up to the cloud before you ever open the editor — the Markup edit changes what's visible in the saved copy, not what Google already has a record of.
What tends to go wrong
A few things catch people out with the Markup approach specifically:
- Mistaking the Blur adjustment for a face tool. It only appears on Portrait-mode photos and only affects the background, never the subject.
- Drawing at the wrong zoom level, leaving a gap at the hairline or jaw that isn't visible until you zoom back out.
- A pen colour close to skin tone can look covered on a small preview but still show through at full resolution.
- Assuming the edit is saved over the original — Google Photos always creates a new file, so both versions exist unless you delete the source.
Google Photos vs. Deface
| Google Photos | Deface | |
|---|---|---|
| Time for one still face | 1–2 minutes of freehand drawing | About half a second |
| Moving subject in video | Not possible — no video markup tool | Tracked automatically, frame by frame |
| Multiple faces | A separate hand-drawn stroke per face | Detected together, toggle each on or off |
| Works offline | Editing works locally, but the app is built around your account and cloud library | Fully offline, no account, no upload |
| Removes photo metadata | No | Yes — strips EXIF, GPS and timestamp on export |
| Cost | Free | Free to try, one-time Pro unlock |
The faster way
Deface is built specifically to redact faces, in photos and in video. Import either one and it detects every face on device in about half a second — no freehand drawing, and no confusion with a background-blur slider that was never meant for this.
Choose blur, pixelate, a solid block or an emoji, and it applies to every face detected, switchable afterwards without starting over. Each face gets its own toggle, and a manual region tool covers anything that isn't a face — useful for things like removing location data alongside the face, since Deface strips EXIF and GPS on export, which Google Photos does not.
Frequently asked questions
Does Google Photos have a blur tool for faces?
Not a dedicated one. The app's Blur adjustment blurs the background of Portrait-mode photos, not a specific face. To hide a face, use the Markup pen tool and draw over it by hand.
What does the Blur option actually do in Google Photos?
It adjusts the simulated depth-of-field on photos shot in Portrait mode, softening what's behind the subject to make them stand out more. It has no effect on the subject's own face.
Can I blur a face in a Google Photos video?
No. Google Photos' video editor has trimming, filters and stabilisation, but no Markup tool and no way to draw over or blur any part of a video frame.
How do I permanently hide a face in a photo, not just cover it?
A solid-colour Markup stroke destroys the original pixels underneath it once you save, so there's nothing to recover. A blur-style Markup brush, where available, may be reversible depending on how it's implemented — solid coverage is the safer bet.
Does Google Photos remove location data when I edit a photo?
No. Editing with Markup doesn't strip EXIF or GPS data from the file. Anyone who receives the photo can still see where and when it was taken.
Is there a faster way to blur a face without uploading it anywhere?
Yes. Deface detects faces automatically, works fully offline with no account, and strips the photo's metadata on export.
Does covering a face with Markup mean it's already backed up unblurred?
Possibly. If cloud sync is on, the original photo may already have uploaded before you edit it. The Markup edit changes the file you save afterward, not whatever copy Google already stored.
Blur every face in one tap.
Deface finds the faces automatically, on your iPhone. Nothing is uploaded, nothing is watermarked.
