how to add motion is a great way to take your artwork to the next level. The distance can be in absolute intensity units or, by appending % as a percentage of the maximum possible intensity (255, 65535, or 4294967295). This online utility lets you optimize GIF files and make them use less computer. The -fuzz 7% option is documented here - it treats similar colours as the same colour: Level determines how much optimization is done higher levels take longer, but may have better results. optimizelevel Optimize output GIF animations for space. I ran this against this 1.3MB animated GIF: gifsicle is a powerful command-line program for creating, editing, manipulating. This saves over the original, so make a copy of it first. Which gave me a 723KB file which I think looks good enough for my purposes:įound this tip on Stack Overflow: to reduce the site of an animated GIF, you can use the mogrify tool like this: mogrify -layers 'optimize' -fuzz 7% sqlite-convert-demo.gif So I tried this instead: gifsicle -O3 -colors 128 -lossy -o datasette-launch-smaller-2.gif datasette-launch.gif The reduced colours there were a bit too much for me, especially for the purple gradient buttons at the end. rw-r-r- 1 simon wheel 613K Sep 13 12:54 1 simon wheel 3.7M Sep 13 12:52 datasette-launch.gif tmp % gifsicle -O3 -colors 48 -lossy -o datasette-launch-smaller.gif datasette-launch.gif To compress the images in the 'images/' directory and save them to the same directory, run the following command (overwrites the original files): imagemin images/ -out-dir images. I installed it using brew install gifsicle and ran it like this: /tmp % ls -lah 1 simon wheel 3.7M Sep 13 12:52 datasette-launch.gif Imagemin uses the appropriate plugin based on the image format of the input. You can tweak the number of colours and loss to get it smaller but that’s when it starts to look worse to my eyes ffmpeg -i animation.mov -r 10 -vf scale1200:-1 -loop 0 - gifsicle -optimize3 > animation.gif. Saw your GIF size TIL, and gifsicle -O3 -colors 48 -lossy gets it down to 320k. Keep in mind that flexiGIF's compression is very () slow, magnitudes slower than a standard GIF encoder. Simon Willison’s TILs Compressing an animated GIF with gifsicle or ImageMagick mogrify Using gifsicle run an image-optimizer, such as Gifsicle let flexiGIF optimize the LZW bitstream flexiGIF is a command-line tool and can be easily used with custom scripts, etc. It's source code is a better tutorial on how to write plugins than the webpack documentation is.Compressing an animated GIF with gifsicle or ImageMagick mogrify | Simon Willison’s TILs Used compression-webpack-plugin to learn how to write the plugin.Big thanks to image-webpack-loader for the idea. I'm trying to keep this a small single-purpose plugin, but if you want a feature feel free to open an issue and I'll take a look. (GIFs read from the standard input are written to the standard output.)-Olevel, -optimizelevel Optimize output GIF animations for space. Plus image-webpack-loader is currently using an older version of imagemin. Optimization tools Gifsicle Options-batch, -b Modify each GIF input in place by reading and writing to the same filename. You can also edit animations by replacing, deleting, or. Extracting frames from animations is easy too: gifsicle anim.gif 0 > firstframe.gif. Making a GIF animation with gifsicle is easy: gifsicle -delay10 -loop. This plugin will optimize ANY images regardless of how they were added to webpack. Gifsicle is a command-line tool for creating, editing, and getting information about GIF images and animations. I was suprised that there weren't any Imagemin plugins for webpack, so I made one!īecause I had other things like the favicons-webpack-plugin and responsive-loader that were generating images that I couldn't have image-webpack-loader optimize. A workaround can be found here from They also made an issue upstream which should fix it at the source here. If you get an error similar to Error in parsing SVG: Unquoted attribute value while using SVGO, you most likely have un-quoted attributes in the SVG image. True used to be the default behavior in version 2 of this plugin! Troubleshooting The highest level took a single megabyte off of a 27 mb gif. You can specify three levels of optimization. I tried it on some of the larger ffmpeg-created gifs and it didn’t seem to do a whole lot. If set to true, this plugin will use the original image if the optimization process makes it larger. I first heard about gifsicle a while ago as a tool to optimize gifs.
