Upload two photos, mark matching points, and generate a cross-fade GIF. Everything runs in your browser — nothing is uploaded anywhere.
If a photo was taken at a slight left-right tilt, touch and pull the handle on the left or right edge up or down to straighten it — works best when the subject is upright and centered. Confirm to bake the correction in.
Click a point on Photo A, then the matching point on Photo B. Repeat at least 4 times.
Ping-pong cross-fade loop (0% → 100% → 0% opacity), capped to 800px on the longest side to keep the file size manageable.
