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

Release Date: 2026-04-05
- Universal Acceleration: Migrated all core SIMD operators to Google Highway, enabling high-performance execution on everything from older SSE4 CPUs to modern AVX-512.
- Native ARM64 Port: Full, native support for Windows on ARM architectures (NEON SIMD) with zero performance compromise.
- scRGB Linear Pipeline: A complete architectural shift to a 32-bit floating-point linear rendering pipeline, preserving extreme color precision and dynamic range.
- Ultra HDR GPU Composition: Native hardware-accelerated support for Gain Maps (Google/Samsung/Apple), delivering true-to-life brightness on HDR displays.
- Tone Mapping v2: Advanced HDR-to-SDR roll-off mapping for consistent results on legacy monitors.
- Hardware CMS: Deep integration of ICC profile management directly into the GPU pipeline.
- Soft Proofing: Professional simulation of output profiles (CMYK, Printer, Grayscale) with real-time HUD toggles.
- V4 Profile Support: Robust handling of ICC v4 and Compact ICC profiles.
- Natural Sorting: Browsing order now standardizes to Windows Explorer's natural numeric sorting.
- Loop & Traverse: Decoupled folder looping and subfolder traversal options for granular control.
- Gigapixel Tiling: The new Titan Pipeline dynamically slices massive image datasets into LOD (Level of Detail) tiles, enabling smooth 60fps panning over images that previously caused OOM crashes.
- Smart Pull & Prefetch: Memory is now intelligently streamed. QuickView only decodes and uploads the tiles currently visible on your monitor, predicting panning direction to prefetch adjacent chunks.
- Direct-to-MMF Decode: Zero-copy Memory-Mapped File strategy to pipeline gigantic source images directly to the render composition engine.
- Native JPEG XL (JXL): Full, hyper-optimized support for the next-gen JXL format, backed by parallel HeavyLane workers for massive speedups.
- Pro Design Formats: Full support for Photoshop's Massive Document Format (PSB) alongside instant PSD/PSB thumbnail extraction.
- Shell-Accelerated Gallery: The
TGallery now taps directly into the Windows Explorer Thumbnail Cache, making initial indexing of massive folders completely instantaneous.
- True High-DPI: The interface has been untethered from Windows' legacy scaling. We support explicit native D2D UI scaling with granular manual overrides (100%-250%).
- Always Fullscreen: Command QuickView to automatically launch images in exclusive Fullscreen mode (
Off,Large Only,All) with intelligent auto-exit. - AVX-512 SIMD Resizing: Critical bilinear scaling paths have been unrolled using AVX2/AVX-512 instructions for blazing-fast zooming.
- Visual Benchmarking: Side-by-side comparison with synchronized zoom, pan, and rotation.
- Analytical HUD: Real-time RGB envelope/dual-curve histograms, Entropy, and Sharpness metrics.
- Smart Partition: Integrated interaction divider with automated quality-winner identification.
"Speed is a feature."
QuickView leverages Multi-Threaded Decoding for modern formats like JXL and AVIF, delivering up to 6x faster load times on 8-core CPUs compared to standard viewers.
- Zero-Latency Preview: Smart extraction for massive RAW (ARW, CR2) and PSD files.
- Debug HUD: Press
F12to see real-time performance metrics (Decode time, Render time, Memory usage). (First time use: Please enable Debug Mode in Settings > Advanced)
No more manual .ini editing.
A fully hardware-accelerated Settings Dashboard.
- Granular Control: Tweak mouse behaviors (Pan vs. Drag), zoom sensitivity, and loop rules.
- Visual Personalization: Adjust UI transparency and background grid in real-time.
- Portable Mode: One-click toggle to switch config storage between AppData (System) and Program Folder (USB Stick).
Stay fresh, stay fast.
QuickView automatically checks for updates in the background. When a new version is available, a non-intrusive toast notification will appear. You can install the update with a single click—no browser needed.
Don't just view the image; understand the data.
- Real-time RGB Histogram: Translucent waveform overlay.
- Refactored Metadata Architecture: Faster and more accurate EXIF/Metadata parsing.
- HUD Photo Wall: Press
Tto summon a high-performance gallery overlay capable of virtualizing 10,000+ images. - Smart Extension Fix: Automatically detect and repair incorrect file headers (e.g., PNG saved as JPG).
- Instant RAW Dev: One-click toggle between "Fast Preview" and "Full Quality" decoding for RAW files.
- Deep Color Analysis: Real-time display of Color Space (sRGB/P3/Rec.2020), Color Mode (YCC/RGB), and Quality Factor.
"Compare with absolute precision."
QuickView features a powerful Dual-View Compare Mode built for deep visual analysis.
- Side-by-Side Sync: Synchronized zoom, pan, and rotation between two images, allowing for millimetric inspection.
- Precision HUD: Real-time RGB Envelope Histograms and quality metrics (Entropy/Sharpness) to identify the superior shot.
- Interactive Divider: A smart, translucent divider that identifies the 'winner' of each comparison metric automatically.
"View light as it was meant to be seen."
QuickView 5.0 introduces a world-class color management suite.
- True HDR Panel: SIMD-accelerated peak luminance estimation and "HDR Pro" structural metadata (MaxCLL/FALL).
- Global Soft Proofing: Instantly preview how your photos will look when printed or converted to specialized color spaces.
- Linear workflow: 32-bit internal pipeline ensures zero banding and absolute precision.
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:
- Animation Support: Full playback for GIF/WebP/APNG.
- Frame Inspector: Pause and analyze animations frame-by-frame.
- 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.
| 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.
