grunt-contrib-imagemin - Minify PNG and JPEG images.

Javascript

Select optimization level between 0 and 7. The optimization level 0 enables a set of optimization operations that require minimal effort. There will be no changes to image attributes like bit depth or color type, and no recompression of existing IDAT datastreams. The optimization level 1 enables a single IDAT compression trial. The trial chosen is what OptiPNG thinks it’s probably the most effective. The optimization levels 2 and higher enable multiple IDAT compression trials; the higher the level, the more trials.

Imager.js - Responsive images while we wait for srcset to finish cooking

Javascript

Imager.js is an alternative solution to the issue of how to handle responsive image loading, created by developers at BBC News. There are many responsive image solutions in the wild: srcset, src-n, PictureFill and so on. They are either verbose or hard to debug (and to maintain/integrate). Some of them don't deal well with pixel density and suffer from double asset payload (meaning you end up downloading assets unnecessarily).

lazysizes - High performance and SEO friendly lazy loader for images (responsive and normal), iframes and more, that detects any visibility changes triggered through user interaction, CSS or JavaScript without configuration

Javascript

lazysizes is a fast (jank-free), SEO-friendly and self-initializing lazyloader for images (including responsive images picture/srcset), iframes, scripts/widgets and much more. It also prioritizes resources by differentiating between crucial in view and near view elements to make perceived performance even faster. It may become also your number one tool to integrate responsive images. It can automatically calculate the sizes attribute for your responsive images, it allows you to share media queries for your media attributes with your CSS, helping to separate layout (CSS) from content/structure (HTML) and it makes integrating responsive images into any environment really simple. It also includes a set of optional plugins to further extend its functionality.

SVGInjector - Fast, caching, dynamic inline SVG DOM injection library

Javascript

A fast, caching, dynamic inline SVG DOM injection library. Developed by Waybury for use in iconic.js, part of the Iconic icon system. There are a number of ways to use SVG on a page (object, embed, iframe, img, CSS background-image) but to unlock the full potential of SVG, including full element-level CSS styling and evaluation of embedded JavaScript, the full SVG markup must be included directly in the DOM.

vue-progressive-image - Vue progressive image loading plugin

Javascript

To be able to immediately show some feedback to the user, it is possible to pass a placeholder image, which could be also 1% the size of the main image: it will be blurred so you can go crazy with optimizations here. The progressive-background has a "content" slot, which can hold content that needs to be rendered over the background image and also can hold a preloader. This slot has one property called "visible" that tells you when, for example, a preloader needs to be visible or not.
