images & GIFs
common image formats, DNG and animated GIFs with high-quality scaling, rotation, adjustments and fast same-folder navigation.
extremely lightweight media viewer
no accounts. no cloud.
just a media viewer.
one viewer. three media families.
images, animation, video and lightweight 3D viewing share one compact Windows application.
video
high quality video playback with frame stepping, saved frames, adjustments and the same folder-aware navigation.
STL & 3MF
3D viewing with perspective and orthographic modes, 3D printer build plate, part selection and 3Dconnexion SpaceMouse support.
built to get out of your way.
viewtrious keeps the viewer focused on opening, inspecting and moving through local media instead of building a library around it.
fast by design
native Win32 rendering and Windows system components keep startup and everyday navigation lightweight.
crisp scaling
high-quality scaling uses viewport-bounded Lanczos refinement where it actually helps.
filmstrip navigation
move quickly through same-folder media with a filmstrip that follows the selected file.
media adjustments
exposure, brightness, contrast, shadows, highlights, saturation, sharpness, auto adjustments and presets.
Windows integration
Open With / Default Apps integration, media-family icons, Start Menu installation and STL Explorer thumbnails.
local by design
no viewtrious account, no cloud media library and no background media-upload service.
small because Windows already does a lot.
viewtrious uses native Windows graphics, imaging, media, shell and persistence components wherever practical instead of shipping a heavyweight application framework or bundled codec stack.
