QuickView v5.0

QuickView v5.0 is a high-performance image viewer for Windows that emphasizes HDR rendering and advanced color accuracy. It operates on a professional 32-bit linear scRGB pipeline and uses Google Highway SIMD technology for accelerated processing across modern CPUs. The application runs entirely offline with native ARM64 support and requires no installation.

Its Quantum HDR Engine enables true-to-life brightness composition and professional-grade color management beyond traditional 8-bit limits. End-to-end 32-bit floating point processing eliminates banding for wide-gamut images. Native GPU support handles Google and Samsung Gain Maps to display the full dynamic range of mobile photos. Real-time soft proofing simulates CMYK and printer output profiles through direct-to-GPU ICC management.

The viewer supports multiple formats including JPEG XL, AVIF, HEIF, RAW files such as ARW and DNG, Adobe PSB and PSD, and SVG. Additional capabilities include a real-time SIMD-accelerated RGB histogram, native Direct2D SVG rendering for lossless zoom, an HDR Pro Panel for inspecting metadata like MaxCLL and FALL with peak luminance estimation, natural sorting with seamless folder cycling, and a Designer Mode that provides borderless always-on-top viewing. It is delivered as a single compact portable executable that avoids registry changes or background services.

QuickView is built with C++23/26 and Direct2D for responsive performance. It is licensed under GPL-3.0 and targets technical artists, designers, and photographers who need precise offline image inspection without bloat or telemetry.
