Models and downloads
Everything this site downloads to your device
Every retouching tool here works with no download at all. Two optional pieces are fetched only when you press a button that names them, and one decoder only when you open a HEIC photo. This page lists each file with its exact size, licence and checksum. None of them sends anything back.
Face finder
Places the working region over each face and marks the eyes for the red-eye scan. It returns a box and five points per face — no identity, nothing kept. It is downloaded from our model file server the first time you press Find the face, kept in this browser’s cache, and can be deleted from the desk.

HEIC decoder
iPhones save photos as HEIC, which browsers other than Safari cannot open. The first time you open one, a decoder is loaded from this site so the photo can be read in this tab. JPG, PNG, WebP and the other formats need nothing extra.

Not shipped
Two kinds of model are on the plan and not in this build: a learned spot finder and a face-parsing model that would trace brows, eyes and lips exactly. Neither ships until its weights and training data are cleared for commercial use, it fits the size limit, and its accuracy has been measured across skin tones and published. Until then the spot finder is a plain measurement that proposes and never applies, and the face finder places an oval rather than tracing features.
