Fast by design
Win32, WIC and Direct2D keep navigation extremely lightweight.
No accounts. No cloud.
Just an image viewer.
Viewtrious is a Windows image viewer engineered for extreme efficiency, instant startup, high-quality rendering, and zero tolerance for feature bloat.
Built to get out of your way.
No heavyweight framework, no background process, and no giant startup sequence between you and the image.
Crisp scaling
Quality mode uses fast interactive rendering with viewport-bounded Lanczos refinement.
Modern formats
JPEG, PNG, BMP, HEIC/HEIF, GIF and supported system RAW codecs fit into one compact viewer.
Animated GIF
WIC playback with bounded memory, transparency and correct frame composition.
Simple navigation
Keyboard, mouse, filmstrip and fullscreen controls without turning the viewer into a media suite.
Portable-minded
A tiny executable with no bundled codec stack or heavyweight runtime requirement.
Public release coming later.
Viewtrious is actively in development by Ortrious. This page is the official home for the project.
