XnView

A capable image browser for hundreds of formats

XnView is a practical Windows image viewer and file browser built for people who work with many picture types and want one place to view, sort, and convert them. Its biggest strength is format support: it can display more than 400 image formats, which makes it useful for mixed photo folders, old image archives, and files received from different devices or applications.

The interface feels familiar because it resembles the standard Windows file explorer. Folders appear on the left, file contents appear in the main area, and a preview panel lets you inspect images without opening separate windows. When viewing folders, XnView can show thumbnails along with details such as resolution and file type. It can also preview some text-based files, such as INI or TXT, directly in the preview area.

For everyday photo management, XnView offers more than simple viewing. You can rotate and crop images, adjust brightness, gamma, and color balance, apply filters and effects, and create full-screen slideshows. Batch processing is another useful feature, especially if you need to convert many files at once. Supported output formats include common choices such as JPEG, PNG, TIFF, GIF, BMP, ICO, and others. The program also includes a screen capture tool and options for thumbnail output resolution.

Performance is a plus. XnView loads quickly and is designed to browse images without frequent lag or crashes. It can also handle some media formats, including MP3 and AVI, which adds flexibility beyond still images.

There are limits to keep in mind. XnView is not a text editor, even if it can preview certain text files. It may also fail to recognize some files if their extensions have been changed, and some extension handling can feel strict, such as treating LOG and TXT files differently.

Overall, XnView is best for Windows users who want a free, approachable image organizer with strong format support and useful batch tools. It is especially suitable for beginners and home users, while still offering enough functions for more demanding photo collections. It is compatible with Windows 11.
