A small collection of hand-crafted bash scripts that feed my animated GIF addiction:
- webp2gif Script to convert animated webp files to looping, animated gifs. Will try to optimize filesize via gifsicle if it's installed.
- sidebyside.sh script that takes a large GIF, and splits it into multiple gifs that you can display side by side in slack.
- Imagemagick
- webp tools
- [Optional] gifsicle
On a mac with homebrew, you can do brew install imagemagick webp gifsicle to get all requirements.
Most linux distributions should have packages for these utilities.
Just ensure the binaries are on your $PATH.
$ ./webp2gif.sh -h
usage: ./webp2gif.sh <file.webp> [file.webp file.webp...]
Converts listed webp files to infinite-looping animated gifs.
If gifsicle is installed, will optimize the converted gif.Example:
Inspiration from this stack exchange post.
Splits a lengthy gif into a variable number of segments, then resizes each to a max of 128x128 or a user-provided NxN size, whichever is smaller.
Actual dimensions may be smaller, and vary depending on the actual dimensions of the input gif.
For example, given the following input gif:
You will get a series of gifs that could be uploaded to Slack as individual emoji. You can then chain them together in your messages like so:
:teamwork-1::teamwork-2::teamwork-3::teamwork-4::teamwork-5:
And you'll get the following awesome mega-gif:

$ ./sidebyside.sh
usage: ./sidebyside.sh <file.gif> [NxN]
Splits a lengthy GIF into a variable number of segments,
and then resizes each segment to a max of 128x128 or a user-provided NxN,
whichever is smaller.
Actual dimensions may be smaller, depending on the dimensions of
the input GIF.
The intended use-case is for displaying multiple emoji in a row
on a messaging service like Slack, eg:
:emoji-1::emoji-2::emoji-3:
