Paid plans start at $4.99 and are available as both one-time and monthly plans. Even better, if you already use ShortPixel Image Optimizer, you can use the same credits for ShortPixel Adaptive Images! How does it work? Different visitors have different devices (laptop, mobile phone, tablet), each with its own screen resolution. ShortPixel AI takes into account the resolution of the device and then provides the right size image for each placeholder. Let us take a web page with a single image of 640×480 pixels. When viewed from a laptop, the image retains its 640×480 pixel size, but is optimized and delivered from our CDN. When the same web page is viewed from a mobile phone, the image (for example) is resized to 300×225 pixels, optimized, and delivered via our CDN. In this way, neither time nor bandwidth is wasted for visitors.

Email https://shortpixel.com/contact Twitter https://twitter.com/shortpixel WP CLI commands Use the following WP CLI commands to clear the CSS cache and the Low Quality Image Placeholders: wp shortpixel clear_css wp shortpixel clear_lqips For developers If there are main images in the Media Library that end with the usual thumbnail size suffix (e.g. -100×100), please set this in wp-config.php: define('SPAI_FILENAME_RESOLUTION_UNSAFE', true); If you need to do post-processing in JavaScript after the image/tag has been updated by ShortPixel AI, you can add a callback like this: jQuery( document ).ready(function() { ShortPixelAI.registerCallback('element-updated', function(elm){ // elm is the jQuery object, elm[0] is the tag console.log("element updated: " + elm.prop('nodeName')); }); }); To change the original URL of the image that is detected by ShortPixel, use this filter that receives the original URL: add_filter('shortpixel/ai/originalUrl', 'my_function'); To return your own custom URL for each language domain for the same website (single plugin installation), use this filter: add_filter(‘shortpixel/ai/cdnUrl’, function($cdn_url) { switch($_SERVER[‘HTTP_HOST’]) { //this is the domain name without protocol case ‘mydomain.com’: //that’s your main domain return “https://images.mydomain.com/spai”; case 'mydomain.fr': //that's your french language domain return "https://images.mydomain.fr/spai"; default: return $cdn_url; } }); Sometimes when the option to crop images is enabled, SPAI thinks it is not safe to crop an image, but you want to crop it anyway. Please add this attribute to force cropping: --> this will completely exclude from processing the image which has this attribute; --> this will exclude the image from being lazy-loaded by the plugin; --> this will prevent the image from being resized by the plugin. For adding custom replacement rules use: add_filter('shortpixel/ai/customRules', 'my_function'); The function is given an array and should append ShortPixel\AI\TagRule instances to the given array , as in the example below. A real-world example of custom image attributes, a custom srcset, and a custom JSON data attribute: add_filter('shortpixel/ai/customRules', 'spai_to_iconic'); function spai_to_iconic($tagRules) { //lazy-loaded data-iconic-woothumbs-src attribute $tagRules[] = new ShortPixel\AI\TagRule('img', 'data-iconic-woothumbs-src'); //eager attribute $tagRules[] = new ShortPixel\AI\TagRule('img', 'data-large_image', false, false, false, false, true); //lazy srcset style attribute. $tagRules[] = new ShortPixel\AI\TagRule('img', 'srcset', false, false, false, false, false, 'srcset', 'replace_custom_srcset'); $tagRules[] = new ShortPixel\AI\TagRule('div', 'data-default', 'iconic-woothumbs-all-images-wrap', false, false, false, false, 'srcset', 'replace_custom_json_attr'); return $tagRules; } The parameters of the rule are, in this order: * tagName – the tag name * attribute to be replaced * classFilter – only elements having the class, default false * attrFilter – only elements having the attribute, default false * attrValFilter only elements having the attribute with the specified value, default false * mergeAttr – advanced usage (see code), default false * eager – if true the image is replaced server-side, otherwise is lazy-loaded * type – advanced usage (see code), default is ‘url’, can also be ‘srcset’ if it has a srcset or json structure * callback – advanced usage (see code), default false. Needs to be ‘replace_custom_srcset’ if the type is srcset, or ‘replace_custom_json_attr’ if the type is json * quickMatch – advanced usage (see code), default false * frontEager -advanced usage (see code), default false In the same manner if you need a rule to be applied only on the front-end (javascript) you can use the following filter: add_filter('shortpixel/ai/customFrontendRules', 'my_function'); This rule will only be applied by the New JS Engine (so you need to have the option enabled) and is useful if you have content that is rendered by JavaScript and you need the replacement to be made after the content is rendered.
