We can apply that to our command line input above, adding a 105px offset in the x1 parameter of the crop option. You can find that with this simple formula: ((total longest side) - (total desired length)) / 2 To keep that crop in the center, then, I’ll need 105px offset. The greater than sign tells it to take the original file (i.e., “resize-gif.gif”) and save the cropped version as “resize-gif-cropped.gif” in the same directory.Īlmost right…but it’s offset to the top right-hand corner, so we’re not getting the middle of the gif cropped to a 1:1 square. gifsicle -crop 0,0+270x270 resize-gif.gif > resize-gif-cropped.gif Next, we provide the cropped dimension: 270x270 as our width and height respectively. For now, let’s just work on getting it to crop the image. 0,0 will start the crop from the top right-hand corner (i.e., x1 = 0 and y1 = 0). The first two tell it where to start the crop from. The crop option takes four parameters: x1, y1 + width x height. Numbers 1, 3, and 4 are self-explanatorry, so let’s focus on #2.

The crop option (tell it the size, positioning, etc.

According to the documentation, we need to provide four things. Open Terminal and cd to the directory where your image is found. I want my final gif to be a 1:1 square, so 270x270 is my target size. Here’s a gif of the legendary Jurgen Klopp. On a Mac, you can install gifsicle using Home-brew with the following command: brew install gifsicle 2. Here’s a simple step-by-step guide to using it. I recently needed to crop a gif to a square and found this command-line tool for working with gifs called gifsicle.
