Jekyll Responsive Magick

A Jekyll plugin for responsive images using ImageMagick. Works with Jekyll 4.

GitHub RubyGem

Jekyll Responsive Magick (jekyll-responsive-magick) is a Jekyll plugin for responsive images. It adds filters for setting the srcset, width and height attributes of HTML img elements, while automatically generating image variants of configured sizes using the ImageMagick command-line tools. Resized images are cached to minimize build times, regenerated only when the original source image changes.

The plugin has no dependencies besides the ImageMagick command line tools. This is by design, to make it easy to deploy on services such as Cloudflare Pages.

Find it on GitHub or read more about the motivation and implementation in the blog post.
