Is there a command to get the number of frames in a gif?

Is there a command to get the number of frames in a gif? I have some gifs, and I want to convert them into arrays, but I want to limit the array, and structure of the array based on the number of frames in any random gif I happen to feed my program. I was thinking imagemagick might have such an option, but i haven't found it yet.

If you have ImageMagick installed, you can use its identify command as follows

identify /path/to/image.gif 

You'll get details of each frame.

As suggested by steeldriver, you can get the number of images in the sequence directly using the %n output format specifier, however rather annoyingly it appears to print it once for each image. To get a single number you could do

identify -format "%n\n" path/to/file.gif | head -1 

Exiftool will list the Frame Count as part of its extensive output.

This a command and output of an Animated Gif file:

$ exiftool -b -FrameCount giphy.gif 33 

Full exiftool output on the gif:

$ exiftool giphy.gif ExifTool Version Number : 10.10 File Name : giphy.gif Directory : .

One-liner command

Inspired by this article, use this one-liner command:

$ identify drop_caches.gif | wc -l 128 

For more details use:

identify -verbose filename.gif 

This website lets you upload your .gif and analyzes it many ways including the number of frames in it:

The convert provided by Image Magic will convert your .gif into individual .png images one for each frame:

$ convert -verbose -coalesce drop_caches.gif drop_caches.png drop_caches.gif[0] GIF 470x940 470x940+0+0 8-bit sRGB 256c 177KB 0.090u 0:00.099 drop_caches.gif[1] GIF 13x1 470x940+398+704 8-bit sRGB 256c 177KB 0.080u 0:00.089 drop_caches.gif[2] GIF 306x620 470x940+144+130 8-bit sRGB 256c 177KB 0.080u 0:00.089 (... SNIP ...) drop_caches.gif=>drop_caches-125.png[125] GIF 470x940 470x940+0+0 8-bit sRGB 255c 50.3KB 27.100u 0:24.890 drop_caches.gif=>drop_caches-126.png[126] GIF 470x940 470x940+0+0 8-bit sRGB 254c 48.9KB 27.320u 0:25.089 drop_caches.gif=>drop_caches-127.png[127] GIF 470x940 470x940+0+0 8-bit sRGB 254c 48.9KB 27.480u 0:25.269 

FFmpeg way:

ffprobe -v warning -show_frames qqq.gif | grep -c '\[/FRAME\]' 

Gif video is a video, so video analysis tools may also help.

You can use less command too if you have ImageMagick installed.

less +G image.gif 

Total frames is the last # in brackets in image.gif[#]... (starting from 0); Or count with:

less image.gif | wc -l
