PostCard Creator is a user-friendly mobile application designed for Android users, allowing them to transform personal photos into customized postcards. The app offers a variety of design options, enabling users to enhance their images with filters, effects, and emojis, while also providing numerous fonts and text styles for personal messages. Users can quickly create postcards and send them to multiple addresses directly from their smartphones, with Swiss Post managing the printing, mailing, and delivery processes.

The postcards are printed on high-quality 260 g/m2 paper with a glossy finish, measuring 105 × 148 mm. The app supports both paid and free postcard options, with specific mailing conditions for each. Additionally, the service emphasizes sustainability and social responsibility, as the postcards are produced by a Swiss print shop that employs individuals facing physical and mental health challenges. This makes PostCard Creator not only a convenient tool for sending personal greetings but also a socially conscious choice.
