A shared album quietly keeps a quarter of your photo. Measured on one real family trip: 3,174 of 3,225 frames came back at 2,049 pixels wide from a phone that shoots 4,032, and the videos arrived at 720p. Nobody was told.
This keeps the original. Guests add photos from a link with no account and no app, from a phone, a laptop, Dropbox, Google Drive or OneDrive, and what lands is the file their camera made.
Private, invite-only, in build. Event pages open from the link their host sends.
