Google Pagespeed Tools

What It Does

• HTML minification — WebMarkupMin strips whitespace, comments, CDATA sections and optional end tags from rendered pages.
• Per-URL ignore list — Exact or prefix-matched pages are excluded from optimization through a configurable list.
• CSS minification and swap — Replaces stylesheet links with a cached, up-to-date .min.css sibling generated on demand.
• CSS repositioning — Moves stylesheets into head or to just before the closing body tag, optionally including external stylesheets.
• CSS inlining and async loading — Inlines CSS below a byte threshold and loads remaining stylesheets asynchronously with a noscript fallback.
• Critical-path CSS — Injects a configurable inline style block, up to 2000 characters, immediately before the head closes.
• JavaScript minification and repositioning — Swaps script references for .min.js siblings and can move scripts to head or footer.
• Font optimization — Repositions font stylesheet links to head or footer and can load them asynchronously.
• Native image lazy loading — Injects a loading="lazy" attribute into img tags that do not already have one.
• CDN URL rewriting — Independent CDN base URLs for pictures, CSS and JavaScript, each with its own toggle.
• Image compression — Compresses jpg, jpeg, png and gif files in configured folders using Magick.NET.
• Scheduled optimization task — "Google Pagespeed" task runs every 6 hours, refreshing .min.css/.min.js siblings and compressing images.
• Manual admin tools — One-off minify actions for a single picture, CSS or JavaScript URL, reported as admin notifications.
• Built-in HTML minification control — Toggles nopCommerce's own CommonSettings.EnableHtmlMinification from the same configuration page.
