A lightweight image viewer for a fast image preview. It has been developed to have the same viewer available for all major operating systems - Microsoft Windows 11, macos and GNU/Linux.
The main goal is to have a free of charge cross-platform viewer with a simple design and minimum functions that are commonly used.
- Transformations
- Flip (horizontal, vertical).
- Rotation (clockwise and counterclockwise in 90° steps).
- Zoom (in, out, original size, fit to window).
- Metadata information.
- Fullscreen or Window mode.
- Custom background color.
- Custom image border color.
- Remembers recent files.
- Supports Apple's high definition trackpad gestures.
Looking for translators
🗒 If you are a native speaker of the non-US-English language and would like to help localize this application, please, see this guideline on how to join the localization team.
Supported image formats cover the very common formats as well as the rare ones. The viewer does not intentionally demosaic the RAW images, but only displays the embedded thumbnail.
