feh review
A free, open-source viewer for slideshows, thumbnails, image catalogs, and shell-driven workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
feh is a lightweight, configurable image viewer and cataloguer for Unix-like desktop environments, with a particular focus on command-line users. It suits Linux users who want fast access to slideshows, clickable thumbnails, index and montage generation, multiwindow viewing, filelists, configurable sorting, and image information. It also integrates with graphical file managers and supports keyboard and mouse navigation, making it useful for browsing collections without requiring a full photo-management suite.
Its strongest area is breadth within a focused viewer. feh combines slideshow viewing, thumbnail browsing, contact-sheet-style montage generation, captions, list output, built-in EXIF display, wallpaper setting, and custom shell-command actions. Filelists and configurable image sorting add useful control for users who organize images through scripts or structured workflows. The open-source model also makes it available without a paid tier, while the published feature set centers on local image viewing and cataloguing rather than account-based services.
The main trade-off is that feh favors configurable, command-line-oriented workflows over a more visual desktop experience. RAW handling is limited to displaying embedded camera thumbnails when dcraw is available, rather than providing full RAW decoding. Wallpaper setting is designed for X11 desktops, which narrows that feature's environment fit. Choose feh if you value a lightweight open-source viewer with shell actions, image lists, thumbnails, and EXIF information. Choose another tool if full RAW processing or a more visually guided photo workflow is central to your needs.
