What is Posterino?
Posterino is a native macOS photo collage and poster design app that helps users turn their pictures into posters, greeting cards, postcards, and photo layouts. It is designed for people who want polished visual compositions without using a full desktop publishing tool. The app includes ready-made layout styles such as grid, tile, circular, and random arrangements, along with automatic, semi-automatic, and manual layout controls for fine-tuning each page. It also provides a built-in image browser, support for large documents, custom paper sizes, templates, and export to common image formats for sharing or printing. Posterino is published by Zykloid and is available for modern macOS versions on both Apple Silicon and Intel Macs.

Safety overview
Status: Safe
Posterino is a legitimate creative app for working with photo layouts on Mac. Access to your pictures or photo library is normal for its purpose if you choose to import images, and removing it mainly affects your saved app settings and any workflows built around the app. As with any photo tool, review what you export or share if your projects contain personal images.
Recommendation: Keep Posterino if you use it to make collages, posters, cards, or print-ready photo layouts on your Mac. If you no longer use it, you can remove the app to free space, but keep any project files or exported images you still want first.
