Simple Mosaic: Pixelate Photos

An app for hiding the one part of a photo you did not mean to share.

Open it, pick a photo, drag over what should be gone, save. No tutorial, no account, no sign-up.

■ Straight from the Share button
Open a photo from the Share button in Photos or on a screenshot and mask it right there — no need to find the app first.

■ Four ways to hide
・Pixel — the familiar square mosaic
・Blur — when it should blend into the photo
・Glass — like looking through frosted glass, not just a soft focus
・Black — when it has to be gone for certain

A slider sets how strong it is, and the photo updates as you drag.

■ Five shapes
・Brush — hide whatever your finger covers, at any width
・Rectangle — names, addresses, email, QR codes
・Vertical bar — details stacked down the screen
・Horizontal bar — eyes, or a single line of text
・Circle — faces, without a hard edge

Rectangles and circles can be moved, resized or deleted afterwards.

■ Hide every face at once
Tap Hide Faces and the app finds the faces in the photo and covers them together. Detection runs entirely on your device. Anything it gets wrong, you can tap and delete.

■ Nothing is final
Undo and redo are always there, and the eraser brings back anything you covered too much of.

■ What it costs
Every tool is free to use. Saving and sending are free for your first five photos. If you want more, a single purchase removes the limit for good. There is no subscription.

■ Your photos stay on your phone
・Your photos are never sent to a server
・No account
・No uploads
・All editing happens on the device

■ Location data does not travel with it
Masking a photo and then sharing the place it was taken defeats the point. Saved photos have their GPS tag and other metadata stripped by default — you can turn that off in Settings.

Your original photo is never modified. The masked version is always saved as a new photo.

■ What this app does not do
No filters, brightness, cropping, stickers, text, collage or beauty tools. It is not a photo editor. It is a tool for hiding things.

For iPhone and iPad, iOS 18 or later.
