## What it is
ImageGlass is a fast, open-source desktop image viewer supporting 90+ formats including WEBP, GIF, SVG, AVIF, JXL, HEIC, HDR, and camera RAW. Version 10 is a complete rewrite on .NET and Avalonia, providing a unified cross-platform codebase for Windows, macOS, and Linux with a free GPLv3 Classic edition and a paid Pro edition.

## Use cases
- view webp and heic photos without installing codecs
- quickly browse large photo folders
- view svg vector files natively
- play animated gif and webp images
- open camera raw and hdr images
- replace the default windows photo viewer
- set up a managed image viewer deployment across an organization

## When to choose
- you need a fast, lightweight viewer for many image formats across Windows, macOS, or Linux
- you want an open-source alternative to proprietary photo viewers
- you need HDR, RAW, or modern format support out of the box
- you want customizable themes, hotkeys, and command-line control

## When to avoid
- you need full-featured photo editing rather than viewing and quick edits
- you require the Pro features (advanced workflow tools, enterprise licensing) without paying
- you need a mobile or web-based viewer
