QuickView is currently one of the fastest image viewers available on the Windows platform. We focus purely on delivering the ultimate viewing experience—leave the heavy editing to professional tools like Photoshop.
Rewritten from scratch using Direct2D and C++23, QuickView abandons legacy GDI rendering for a game-grade visual architecture. With a startup speed and rendering performance that rivals or exceeds closed-source commercial software, it is designed to handle everything from tiny icons to massive 8K RAW photos with zero latency.
🌐 Multi-Language Support: English, 简体中文, 繁體中文, 日本語, Deutsch, Español, Русский

We don't use generic codecs. We use the State-of-the-Art libraries for each format.
| Format | Backend Engine | Why it rocks (Architecture) |
|---|---|---|
| JPEG | libjpeg-turbo v3 | AVX2 SIMD. The absolute king of decompression speed. |
| PNG / QOI | Google Wuffs | Memory-safe. Outperforms libpng, handles massive dimensions. |
| JXL | libjxl + threads | Parallelized. Instant decoding for high-res JPEG XL. |
| AVIF | dav1d + threads | Assembly-optimized AV1 decoding. |
| SVG | Direct2D Native | Hardware Accelerated. Infinite lossless scaling. |
| RAW | LibRaw | Optimized for "Instant Preview" extraction. |
| EXR | TinyEXR | Lightweight, industrial-grade OpenEXR support. |
| HEIC / TIFF | Windows WIC | Hardware accelerated (Requires system extensions). |

🗺️ Roadmap We are constantly evolving. Here is what's currently in development:
- Tracing Mode: Semi-transparent overlay mode, designed for designers to reference and trace over other windows.
- Video Wall Port: Direct output to multi-monitor visual arrays.
- Plugin System: Open architecture for community-developed codecs and filters.
| Component | Minimum Requirement | Notes |
|---|---|---|
| OS | Windows 10 (1511+) | DirectComposition Visual3 required |
| CPU | SSE4-Capable CPU | Broadened Support (Intel 2008+ / AMD 2011+) |
| Arch | x64 or ARM64 | Native ARM64 support for NEON |
⚠️ Important: QuickView uses Google Highway for dynamic SIMD dispatching. While we've broadened support to SSE4, ARM64 users enjoy full NEON acceleration.
QuickView is 100% Portable.

Developer Note
I maintain QuickView in my spare time because I believe Windows deserves a faster, cleaner viewer. I don't have a marketing budget or a team. If QuickView helps you, the biggest contribution you can make is to Star us on GitHub or share it with a friend.
QuickView stands on the shoulders of giants. Licensed under GPL-3.0. Special thanks to David Kleiner (original JPEGView) and the maintainers of LibRaw, Google Wuffs, dav1d, and libjxl.
