About Posteriza.org
Welcome to Posteriza.org, the web’s most comprehensive unofficial resource dedicated to the legendary photo splitting tool, Posteriza.
🚀 Our Mission
To keep the best free poster printing software alive for modern users. We aim to provide a safe, virus-free download mirror and easy-to-follow tutorials for creating giant wall art on a budget.
Why We Built This Site
We are a small team of digital artists, teachers, and DIY enthusiasts who have been using Posteriza since the Windows XP era. We love it because it does one thing perfectly: it makes big prints simple.
However, as the original developer’s website became outdated and the software ceased updates in 2006, many users faced challenges:
- Finding a clean installer without malware.
- Getting the software to run on Windows 10 and 11.
- Understanding how to use the “cutting lines” feature correctly.
We built Posteriza.org to solve these problems. We manually verify every file, write fresh guides for 2025, and test compatibility on the latest hardware.
