ImageViewer is a lightweight, cross-platform image viewing application built using C++ and the Qt framework. Designed with simplicity and performance in mind, it supports a wide range of image formats, including PNG, JPEG, BMP, TIFF, and more—leveraging Qt’s built-in QImage support for efficient rendering and decoding.
The application features a minimal, distraction-free user interface with essential navigation controls such as zoom, pan, fullscreen toggle, and image switching (next/previous). It’s optimized for speed and responsiveness, making it ideal for quickly browsing large collections of images without unnecessary UI bloat or dependency overhead.
Supports modern and legacy image formats including JPEG, HEIF, WebP, JPEG XL, PNG, AVIF, BMP, GIF, TIFF, and ICO. Also handles vector graphics like SVG for scalable, resolution-independent viewing. RAW photo formats such as DNG, CR2, and NEF are supported, making it easy to preview unedited shots straight from the camera. Photoshop (PSD) file compatibility lets you view layered design files without needing Adobe software.
