ImageGlass for Windows download

Quick overview

ImageGlass is a compact, open-source image viewer for Windows developed by Phap Dieu Duong (also known as d2phap). It’s designed to be fast and lightweight while supporting a broad range of image types. You can install it like a standard program or run it as a portable app from a USB drive.

Core capabilities

Fast loading and smooth image navigation
Compatibility with many file types, including RAW and PSD
Portable and installable distribution options
Simple, uncluttered user interface

Supported file types

ImageGlass can open dozens of formats (more than 70), covering common raster images as well as professional files such as PSD and various RAW variants, making it suitable for casual users and photographers who need quick previews.

Interface and controls

The interface emphasizes clarity and ease of use. A compact toolbar gives quick access to common actions, and the title bar displays useful metadata (file name, path, resolution, and file size) for the currently viewed image. Keyboard shortcuts are available for most actions to speed up browsing.

Toolbar functions include:

Toggle a checkerboard background
Start/stop a slideshow
View a thumbnail strip of images
Zoom in/out on the image
Rotate the current image
Move between images in a folder

Personalization and settings

ImageGlass offers a handful of ways to customize its behavior and appearance:

Apply language packs and choose themes to change the visual style
Reorder toolbar buttons to suit your workflow
Set file associations so certain formats open with ImageGlass by default
Define color profiles and other display preferences

Limitations to be aware of

ImageGlass is strictly a viewer. It does not include image-editing tools (no retouching, adjustments, or advanced editing features). If you need to edit photos, pair ImageGlass with a separate editor.

Alternatives and comparison

If you’re exploring lightweight viewers, comparable options include HoneyView, IrfanView, and FastStone Image Viewer. ImageGlass sits comfortably among them, balancing speed with broad format support and a clean UI.

Verdict

For users who want a fast, no-frills image viewer with wide format compatibility and simple customization, ImageGlass is a solid choice. If editing capabilities are essential, you’ll need a complementary program, but for quick viewing and organizing, ImageGlass performs well.
