Viewnior is a minimalist and lightweight image viewer for the GTK+ desktop environment, designed for speed and simplicity. It offers a clean user interface, focusing on displaying images without unnecessary clutter. Beyond basic viewing, Viewnior provides essential image manipulation features such as rotating, flipping, and cropping images. Users can navigate through images in a folder, start slideshows, view images in fullscreen, and perform actions like copying an image to the clipboard or printing it directly from the application. Its efficiency makes it a good choice for systems where resources are a concern, or for users who prefer a straightforward viewing experience over a feature-rich image editor.

Viewnior is primarily a viewer with basic manipulation capabilities. It does not offer advanced image editing features like layers, filters, or complex adjustments found in more comprehensive graphic software. Its development has seen varying levels of activity, but it remains a functional and stable choice for its intended purpose.

Viewnior supports a wide range of common image formats, including JPEG, PNG, GIF, TIFF, WebP, and BMP, among others. This broad compatibility is achieved through its reliance on the GDK-Pixbuf library, which handles various image decoding tasks.

Viewnior offers numerous keyboard shortcuts to enhance user efficiency. Common shortcuts include:
Arrow Keys for navigating between images.
F for toggling fullscreen mode.
S for starting/stopping a slideshow.
Esc to exit fullscreen or slideshow modes.
R for rotating the image.

Viewnior emerged as a fast and simple alternative to more complex image viewers in the Linux ecosystem, particularly catering to users seeking a lightweight GTK-based application. Its development has focused on providing core image viewing functionalities with a clean interface, making it a popular choice for default image viewing in many minimalist desktop setups. It was designed to be quick to launch and responsive, a key differentiator from some other viewers that might have a larger footprint or longer startup times.
