ImageGlass — Lightweight Image Viewer for Windows 11/10

ImageGlass is a lightweight and versatile free image viewer for Windows PCs, designed to replace Photo Viewer in Windows OS, especially in cases where Photo Viewer struggles to display PNG and GIF files. The software continues to improve with each new version, introducing innovations, features, and bug fixes.

As an open-source, straightforward image viewer, ImageGlass offers impressive speed due to its lightweight nature, making it a great option for Windows users. The app supports the most common image formats, and users can easily customize the list of supported extensions. ImageGlass for Desktop (64-bit) includes several built-in shortcut keys to streamline daily workflows.

First-Launch Configuration Screen
This feature allows quick setup upon the tool's first launch. Users can select their preferred language, layout mode, theme, or set the app as their default photo viewer.

Color Picker Tool
ImageGlass includes a Color Picker tool that lets users extract colors from images and automatically converts them into four formats: RGBA, HEXA, CMYK, and HSL.

Enhanced Real-Time File Updates
The software instantly updates the current viewing image and other images in the folder when changes are made. This feature also includes a thumbnail bar for easier navigation.

Support for New Image Formats
By utilizing the ImageMagick library, ImageGlass now supports viewing over 100+ image formats. Users can easily add new formats through a user-friendly interface in the Settings dialog, though some additional software may be required for compatibility.

Quick Image Editing with Favorite Apps
ImageGlass provides a convenient command for editing images. By pressing Ctrl + E, the software opens the image in an associated app. Users can change the default editing app anytime via the Settings dialog.
