Japan's most widely used messenger app. Many people already have it installed, and you can share photos through groups and the album feature. However, be aware of automatic photo compression and sharing scope management.
Google's cloud storage service. Create shared albums for multiple people to view and add photos. Great for long-term storage, but everyone needs a Google account.
A short-range wireless transfer feature built into Apple devices. Transfer photos at original quality and high speed to nearby iPhones and Macs. However, it only works between Apple devices and is not suited for large group sharing.
A. The biggest difference is image quality. LINE auto-compresses photos, making them unsuitable for printing or photo books. PicTomo maintains up to 4K (4096px) high quality and allows ZIP batch downloads. PicTomo also lets people share photos even without knowing each other's LINE contacts.
A. Google Photos requires everyone to have a Google account, but PicTomo needs no account. PicTomo also auto-deletes after expiration, making it ideal for temporary event photo sharing. Google Photos, on the other hand, is better for long-term storage.
A. PicTomo is the easiest. No app installation or account registration needed — just share a QR code or URL and anyone can join immediately. Even those who struggle with smartphones or elderly users can browse and upload photos simply by scanning a QR code.
