SnapMerge

SnapMerge takes two or three near-identical group photos and merges them into one picture where everyone looks their best, with open eyes and better expressions. It is made for burst shots, family portraits, travel groups and event albums.

You upload two or three shots from the same moment, each up to 6 MB, and the tool compares each person's expressions across frames. The result uses faces taken from your own source pixels rather than generated portraits, so people still look like themselves.

The site includes example images, a quality page and an FAQ for common questions. A pricing page exists, but plan details were not captured in the reviewed text, so check it before relying on it.
