If you have the time and patience, I recommend -O3 as was able to get much more optimized GIFs with this method. Gifsicle -O3 animation.gif -o animation-optimized.gif -O3 Try several optimization methods (usually slower, sometimes better results).-O2 Also uses transparency to shrink the file further.cd (change into) the directory containing the GIF images then issue the following command to create the animated GIF all.gif : gifsicle -colors 256 -d 100. -O1 Stores only the changed portion of each image. put all the GIF images, appropriately named so that they fall in the correct order of appearance when listed/sorted alphabetically (sometimes tricky), in one folder/directory. ![]() and the math that led us to our getimagesize()-compatible calculations up above would tell us that to fit a 500×281 image in a 150×150 box, our target dimensions would be 267×150. Gifsicle has three types of GIF optimization to choose from: Using Gifsicle to resize and crop animated gifs without distorting the image by changing its intrinsic aspect ratio. gifsicle can resize GIFs, merge GIFs, and do just about anything you'd hope you could do with a GIF. Another handy GIF manipulation library, gifsicle, has a few built in methods for optimizing GIFs.īefore jumping into the GIF optimization commands, it's important to point out that gifsicle is much more than a GIF optimizer. ![]() Since GIFs can be taxing on the user's machine, it's best to optimize GIFs for top performance. I've written a lot about converting different media types lately, especially GIFs, including Convert Video to GIF or GIF to Video, Detect if a GIF is Animated, and Get the First Frame of an Animated GIF with ImageMagick, but whether it's ImageMagick or ffmpeg doing the work, GIFs do not always come out optimized.
