Mosaico: Pixelate Photos

Hide anything in a photo in seconds. Draw a box — it's pixelated instantly. Smart text detection finds names and numbers for you. 100% on-device, no ads, no tracking.

Mosaico hides the sensitive parts of a photo in seconds. Drag a box over what you want covered — a name, an address, a face, a screen — and it's mosaicked the moment you lift your finger.

SMART TEXT DETECTION One tap finds all the text in your photo using on-device recognition. Tap the highlighted regions you want masked — no careful tracing needed.

PRECISE, EDITABLE, REVERSIBLE • Pinch to zoom up to 8× for pixel-precise masking • Every box stays editable: move it, resize it, or remove it at any time • Live preview while you drag • Full undo and redo • Two styles — Polygon (crystallize) and Square (pixelate) — with adjustable tile size

PRIVATE BY DESIGN • Everything happens on your iPhone — Mosaico has no network access at all • No photo library permission needed: the system picker shares only the photo you choose • Saving is non-destructive — your edit is written as a new photo, the original is never touched • No account, no ads, no analytics, no data collected

Share the result directly to any app, or save it to your library at full resolution.
