We are the MozFace team. You photograph an item to sell on Mercari, eBay, or Facebook Marketplace, and the shot turns out fine — until you look past the item. Behind it sits your room: a stack of mail, a calendar with handwriting, a nameplate by the door, maybe a family member walking through. A listing photo is meant to show one thing, but it quietly shows your whole living space. This article covers how to keep the item sharp while hiding everything around it.
What the background gives away in a listing photo
The item is in focus, so that is where your eyes go. Buyers, though, see the frame as a whole. The most common giveaways are documents and mail with your name or address, a nameplate, intercom panel, or apartment number, and family or roommates caught in the background. None of these help the sale, and together they sketch out where you live and who you are.
It is hard to catch in the moment because the room is just your everyday surroundings. The label you set down, the photo on the shelf, the post on the counter — they blend in until a stranger is looking at them through your listing. Once posted, the photo has already been seen by everyone browsing.
Cover background details with the manual brush
Details that are not faces — a name on a document, a nameplate, a calendar — get hidden with the manual brush you trace with your finger. Pick mosaic, blur, or a stamp, raise the strength, and you can cover text until it can no longer be read. Adjust the brush size and even a thin line of handwriting fits.
The advantage over cropping is that you keep the composition. You can leave the item large and crisp while turning only the clutter behind it into a mosaic. The edited photo saves as a separate file, so the original stays exactly as it was.
Auto-detect the people in the background
When a person is in the frame, MozFace runs on-device AI that detects every face and opens with everyone already blurred. A roommate passing behind you is covered along with the rest, so you do not have to spot them yourself. All processing stays on the device, and your photos are never uploaded.
If a face that is fine to show ends up blurred, one tap reveals it. Because hiding is the starting point, your task is deciding what to show rather than remembering what to hide — so the person in the back rarely slips through.
A quick check before you list
Before posting, scan the four corners and the surfaces around the item: any text, any reflection in glass, any face. Hide the personal parts and leave the item as is. Whether a particular photo is fine to post is ultimately your call, but a 30-second sweep of the background removes most of the risk.
In a listing photo, the room behind the item often reveals more than the item itself. Cover documents and nameplates firmly with the manual brush, and let auto-detect handle the faces. Combine the two and a clean listing photo is ready in tens of seconds.

What should I watch for in the background of a listing photo?
Documents and mail with your name or address, a nameplate or apartment number, and family or roommates caught behind the item. The background often reveals more about you than the item does, so scan the corners before posting.
Can I keep the item sharp while hiding only the room?
Yes. Unlike cropping, you do not cut the composition. You blur or mosaic only the parts you want to hide, such as a document or a face, and leave the item itself untouched.
Do I have to find every person myself?
No. MozFace detects faces automatically and opens with everyone blurred, so a person walking through the back is covered too. You only tap to reveal a face that is fine to show.
Are my photos ever sent over the internet?
In MozFace, face detection and editing happen entirely on your device, and your photos are never sent to any external server. It works even with no signal.
