Compile-time switches in this build:

libcurl remote file support enabled

Xinerama multi-monitor support enabled

libexif builtin EXIF reader available

inotify-based auto-reload of changed files enabled

is a light-weight, configurable and versatile image viewer. It is aimed at command line users, but can also be started from graphical file managers. Apart from viewing images, it can compile text and thumbnail listings, show (un)loadable files, set X11 backgrounds, and more.

Features include filelists, various image sorting modes, custom action scripts, and image captions.

can be controlled by configurable keyboard and mouse shortcuts, terminal input and signals. When no file arguments or filelists are specified and

is not used,

displays all files in the current directory.

EXIF tags are supported either using exiv2 / exifgrep via

or as a builtin feature by compiling

with exif=1. In this build of

builtin EXIF support is available.

is based on various modes, which are selected at startup by command line options.

Slideshow mode is the default. It opens a window and displays the first image in it; the slideshow position can be advanced

using keyboard and mouse shortcuts. In slideshow mode, images can be deleted either from the filelist or from the disk, a changed filelist can also be saved to the disk and reopened at a later time. An image can also be read from stdin via

Montage mode forms a montage from the filelist. The resulting image can be viewed or saved, and its size can be limited by height, width or both.

Index mode forms an index print from the filelist. Image thumbnails are shown along with the filename, size and dimensions, printed using a truetype font of your choice. The resulting image can be viewed or saved, and its size can be limited by height, width or both.

Thumbnail mode is like index mode, but the mini-images are clickable and open the selected image in a new window.

Multiwindow mode shows images in multiple windows, instead of as a slideshow in one window. Don’t use with a large filelist ;)

List mode doesn’t display images. Instead, it outputs an

listing of the files in the filelist, including image info such as size, number of pixels, type, etc. There is also a Customlist mode which prints image info in a custom format specified by a printf-like format string.

can also list either all the loadable files in a filelist or all the unloadable files. This is useful for preening a directory.

can open any format supported by imlib2, most notably jpeg, png, pnm, tiff, and bmp. The gif format is also supported, but only for static images. In case of animations, only the first frame will be shown. If the convert binary

is available, it also has limited support for many other file types, such as svg, xcf and otf. If dcraw is available,

also supports RAW files provided by cameras and will display the embedded thumbnails. Use

with a non-negative value to enable support for these formats.

As Imlib2 may take several seconds to determine whether it can load a file or not

checks each file’s header before loading it. If it looks like an image, it is passed on to Imlib2, otherwise, it is assumed to be unloadable. This greatly improves performance when working in directories with mixed files

If you think that Imlib2 can load a file which

has determined to be likely not an image, set the environment variable

to pass all files directly to Imlib2, bypassing the header check. The environment variable’s value does not matter, it just needs to be set.

Specify a shell command as an action to perform on the image. In slideshow or multiwindow mode, the action will be run when the action_0 key is pressed, in list mode, it will be run for each file. In loadable/unloadable mode, it will be run for each loadable/unloadable file, respectively. In thumbnail mode, clicking on an image will cause the action to run instead of opening the image.

will reload the current image instead of switching to the next one

or closing the window

after executing the action. If

is specified

instead of

The action will be executed by /bin/sh. Use format specifiers to refer to image info, see

for details. Example usage:

option.

Automatic reload is not supported in montage, index, or thumbnail mode.

Automatically rotate images based on EXIF data. Does not alter the image files.

Zoom pictures to screen size in fullscreen / fixed geometry mode.

Enables

Note: This option needs to load all images to calculate the dimensions of the

window, so when using it with many files it will take a while before a

window is visible. Use

to get a progress bar.

Make the window fullscreen. Note that in this mode, large images will always be scaled down to fit the screen, and

only affects smaller images and never scales larger than necessary to fit the screen size. The only exception is a

of 100, in which case images will always be shown at 100% zoom.

When combined with

this option only affects images opened from the thumbnail overview. The thumbnail list itself will still be windowed.

Use a fixed window size as specified in the X-style geometry

e.g. 640x480. An optional +x+y window offset can be specified. Combine with

to scale down larger images like in fullscreen mode. Note that this option does not enforce the window size; changing it by a tiling WM or manually is still possible. However, auto-resize remains disabled.

Hide the pointer

Use

as background for transparent image parts and the like. Accepted values: default, checks, or an XColor

When viewing files with HTTPS, this option disables all certificate checks. It allows images on sites with self-signed or expired certificates to be opened, but is no more secure than plain HTTP.

When viewing files using HTTP,

normally deletes the local copies after viewing, or, if caching, on exit. This option permanently stores them on disk, either in the directory specified by

or in the current working directory.

If you only care about one parameter, set the other to 0.

Enable montage mode. Montage mode creates a new image consisting of a grid of thumbnails of the images in the filelist. When montage mode is selected, certain other options become available. See

Disable slideshow mode. With this setting, instead of opening multiple files in slideshow mode, multiple windows will be opened; one per file.

When loading images via HTTP, ImageMagick or dcraw,

will only load/convert them once and re-use the cached file on subsequent slideshow passes. This option disables the cache. It is also disabled when

is used. Use it if you rely on frequently changing files loaded via one of these sources. Note that it will impair performance.

Don’t jump to the first image after resorting the filelist.

Don’t load or show any menus.

By default, window sizes are limited to the screen size. With this option, windows will have the size of the image inside them. Note that they may become very large this way, making them unmanageable in certain window managers.

Disable Xinerama support.

when using

or the save_image or save_filelist command. By default, files are saved in the current working directory.

Preload images. This doesn’t mean hold them in RAM, it means run through them and eliminate unloadable images first. Otherwise they will be removed as you flick through. This also analyses the images to get data for use in sorting, such as pixel size, type etc. A preload run will be automatically performed if you specify one of these sort modes.

Don’t report non-fatal errors for failed loads. Verbose and quiet modes are not mutually exclusive, the first controls informational messages, the second only errors.

When viewing multiple files in a slideshow, randomize the file list before displaying. The list is re-randomized whenever the slideshow cycles (that is, transitions from last to first image).

Recursively expand any directories in the command line arguments to the content of those directories, all the way down to the bottom level.

Don’t recursively expand any directories. This is the default, but this option is useful to override themes containing

will either show the next one or quit. However, if an image still exists, but can no longer be loaded,

will continue to try loading it.

Setting this option causes inotify-based auto-reload to be disabled. Reload is not supported in montage, index, or thumbnail mode.

Reverse the sort order. Use this to invert the order of the filelist. E.g. to sort in reverse width order, use

Scale images to fit window geometry (defaults to screen size when no geometry was specified). Note that the window geometry is not updated when changing images at the moment. This option is recommended for tiling window managers. This option is ignored when in fullscreen and thumbnail list mode.

In tiling environments, this also causes the image to be centered in the window.

Scroll

Draw to an existing X11 window by its ID

This option is intended for use with software such as xcreensaver or xsecurelock, which provide a window for other applications to draw into. Unexpected things will happen if you specify a window belonging to software which does not expect

to draw into it or attempt to use options or keybindings which affect window attributes, such as full-screen mode.

All other monitors will be filled black/white. This is most useful in a Xinerama configuration with overlapping monitors. For instance, assume you have two overlapping displays (index 0 and 1), where index 0 is smaller. To center a background on the display with index 0 and fill the extra space on index 1 black/white, use

A note about pan and zoom modes: In pan mode, if you reach a window border but haven’t yet panned to the end of the image,

When clicking the zoom button and immediately releasing it, the image will be back at 100% zoom. When clicking it and moving the mouse while holding the button down, the zoom will be continued at the previous zoom level. The zoom will always happen so that the pixel on which you entered the zoom mode remains stationary. So, to enlarge a specific part of an image, click the zoom button on that part.

Imlib2 releases prior to 1.7.4 are unable to load gif, tiff, and webp images if the filename does not end with gif, tiff, or webp, respectively. Notably, this means that feh is unable to show gif, tiff, and webp images from stdin or network URLs on systems using an Imlib2 version older than 1.7.4.
