Easy Optimizer – PageSpeed, Cache & Core Web Vitals (Unused CSS, Delay JS, Lazy Load) vs DietPress

Speed up your WordPress site and improve your Google PageSpeed score from a single dashboard. Easy Optimizer is a free, all-in-one performance plugin that can replace the 3–5 separate speed plugins most sites run today — page caching, unused-CSS removal, JavaScript delay/defer, image lazy loading, LCP preloading, WebP/AVIF delivery and more — to help you pass Core Web Vitals: Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS) and Interaction to Next Paint (INP). It runs on Apache, Nginx, LiteSpeed and OpenLiteSpeed, and is fully WooCommerce-aware. One cache plugin, one dashboard, no premium upsells for core features. Prefer to keep your current cache plugin? Turn off the modules that overlap and use only the tools you want (see the FAQ). Every toggle maps to a specific Google Lighthouse recommendation — enable it, save, and your Core Web Vitals improve immediately. Features you don’t enable never touch your page load or your admin. Core Features Full Page Caching: Serve static HTML with sub-millisecond TTFB, with separate mobile and desktop caches and automatic sitemap-based preloading that warms your pages in the background. Compression & Browser Caching: Turn on Gzip or Brotli text compression and long-lived browser-cache (Expires) headers to shrink transfer size and stop repeat visitors re-downloading the same assets — resolving Lighthouse’s “Enable text compression” and “Serve static assets with an efficient cache policy”. Redis Object Cache: Add a persistent object cache that keeps repeated database and option lookups in Redis, cutting MySQL load on dynamic, logged-in and WooCommerce pages. Works with Relay, PhpRedis or the bundled Predis client (no PHP extension required) and reads your host’s WP_REDIS_* constants automatically. It defers to any object-cache drop-in already installed instead of overwriting it, never edits wp-config.php, and includes a one-click flush plus a live status panel (connection, memory, Redis version). Remove Unused CSS: Fix Lighthouse’s “Reduce unused CSS” by serving a slim, per-page-type stylesheet — eliminating render-blocking CSS and lifting your LCP. A built-in fail-safe keeps your original styles until a valid stylesheet is generated, so pages never render unstyled. Minify CSS & JavaScript: Strip comments and whitespace from your local CSS and JS files, caching each minified file on disk so it is processed only once. Already-minified files are skipped, and relative url()/@import paths are rewritten so assets keep resolving. Works independently of Remove Unused CSS and Delay JS. Delay & Defer JavaScript: Cut Total Blocking Time and improve INP by delaying script execution until user interaction, or by deferring scripts natively. jQuery is excluded by default, and you can exclude any script that needs to run early. Smart Lazy Loading: Defer offscreen images, iframes, videos and CSS background images, and add missing width/height attributes to prevent layout shift (CLS). Automatic LCP Preload: Detect each page’s Largest Contentful Paint image and preload it — including responsive srcset, and CSS background heroes — stored per URL so every page preloads its own correct hero for faster visual loading. Image CDN (WebP & AVIF): Rewrite your image URLs to a global CDN that serves modern WebP/AVIF formats and every responsive size, addressing Lighthouse’s “Serve images in next-gen formats”. Optional and off until you enable it. Prefetch Pages: Pre-fetch links as visitors hover — with rate limiting and automatic back-off on a struggling server — making navigation feel like an instant single-page app. Font Optimization: Add font-display: swap so text stays visible during webfont loads, with optional per-device font preloading learned from a lightweight beacon. Bloat Removal: 15 independent toggles to safely switch off unused WordPress core scripts and features (emojis, embeds, XML-RPC, jQuery Migrate, Dashicons, Block Library CSS and more). Database Cleanup & Optimization: Schedule cleanups of revisions, auto-drafts, trashed posts, spam and transients — each with a pre-cleanup snapshot so you can restore safely. The built-in Autoload Health auditor finds the heaviest autoloaded options and lets you switch off the ones you don’t need, directly resolving the Site Health warning “Autoloaded options could affect performance.” Heartbeat & Cron Manager: Limit WordPress Heartbeat frequency and throttle WP-Cron from the dashboard (no wp-config.php edits), and view, run or delete scheduled cron events. Cloudflare Integration: Purge your Cloudflare edge cache (tag-based or full zone) whenever the page cache clears, and test your API connection instantly without saving credentials first. Hosting Integrations: Detect your environment and purge server-level cache on managed hosts including Kinsta, WP Engine, SiteGround, Cloudways, GridPane, RunCloud, SpinupWP, Rocket.net and WordPress.com. Accessibility & SEO Fixes: Resolve common Lighthouse accessibility warnings in real time — missing form labels, ARIA names, iframe titles and un-crawlable links — without editing your theme. PageSpeed Speed Test: Run a Google PageSpeed test from your dashboard and compare your score with and without Easy Optimizer, for both mobile and desktop, including Core Web Vitals (LCP, CLS, INP). Works out of the box, or add your own free Google API key for unlimited tests. Debug Issues Panel: If a page ever looks wrong, switch individual optimizations off for a single page load and find the cause in a couple of clicks — no settings changed, no cache cleared, and no private browsing window needed. It tells you which feature caused it and takes you straight to the exclusion field that makes the fix permanent. Find Slow Plugins & Themes (Backend Analyzer): Profile any page or your admin area on demand to see exactly which plugins, themes and database queries take the most time — so you can pinpoint what is slowing your site down. Nothing runs for real visitors, so there is no added overhead. PageSpeed Insights & Lighthouse Recommendations Addressed Lighthouse 13 renamed and merged many performance audits. Where the name changed, the previous wording is shown in brackets so you can match either against your report.

Works With Your Setup WordPress & PHP: WP 6.4+ and PHP 7.4+ Web Servers: Apache, Nginx, LiteSpeed, OpenLiteSpeed WooCommerce: Fully compatible. Cart, checkout, and my-account pages are automatically excluded from caching and optimization to protect the purchase flow. Page Builders: Elementor, Beaver Builder, Divi, Gutenberg, Bricks, Oxygen, Breakdance. A Free Alternative to Premium Speed Plugins Easy Optimizer is a genuine free alternative to paid performance plugins such as WP Rocket, FlyingPress and Perfmatters: page caching, Remove Unused CSS, Delay/Defer JavaScript, LCP preload, lazy load, Cloudflare and hosting-cache purging, database cleanup and the Backend Analyzer are all included, with no premium-locked features and no upsells. Run it as a complete all-in-one, or use just the tools you need alongside your existing setup — the only rule is to never run two of the same optimization (especially two page caches) at once. External Services Each service below is optional and used only for the feature noted. FluxPress Adaptive Images (optional, paid) — with Smart Images connected, your public image URLs are rewritten to your CDN for WebP/AVIF conversion and resizing. Contacts fluxpress.io with your license key and site URL on connect and about hourly. Originals are never uploaded.

It never collects your email address, IP address, user data, or site content.

DietPress is a free WordPress speed optimization plugin with a built-in page cache. Page caching, browser caching, GZIP and Brotli compression, deferred JavaScript, critical CSS, image loading attributes, preloading, locally hosted Google Fonts and selective asset loading, all in one plugin and all free. And it goes further than a caching plugin: it also puts WordPress itself on a diet, switching off the features your site never uses. It pairs that with a clean, risk-based interface. Everything is configurable, the optimizations are already on by default, and nothing is hidden behind a paid tier. Activate it and your site is faster, or open the settings and tune every detail. By default WordPress loads functions, services and scripts that most sites do not need. They slow down loading times and consume hosting resources. DietPress lets you trim that fat and apply battle-tested performance tweaks, with a clear description of what each option does and what might break, organized by risk level so you always know what is safe. WHY CHOOSE DIETPRESS Page caching, for free. Serve anonymous visitors a copy stored on disk instead of building the page again. The feature people buy WP Rocket or a NitroPack subscription for, with no licence and no monthly fee. No drop-in, no changes to wp-config.php. Unlike WP Super Cache or W3 Total Cache, DietPress installs no advanced-cache.php and never edits wp-config.php. Switching it off leaves your site exactly as it was, with nothing orphaned behind. It tells you why. Most cache plugins leave you guessing when nothing is cached. DietPress reports its own status, tests itself against your home page, and names the exact reason a page was skipped. WooCommerce-safe by design. Carts, checkout, my account and any visitor carrying a cart cookie always get the live site, so nobody ever sees somebody else’s basket. Diet as well as speed. Where Perfmatters focuses on disabling scripts, DietPress covers that ground and adds page caching, critical CSS, local Google Fonts and a dashboard, admin and email cleanup, in one plugin. Light on your server. No account, no external service, no telemetry, no upsell nags. Everything runs on your own hosting. WHAT THE PAGE CACHE DOES TO YOUR RESPONSE TIME Measured on a WordPress 7.0 install with GeneratePress, WooCommerce and a 76 product catalogue, PHP 8.5, taking the median of 15 requests per URL. Your own hosting will give different figures, but the shape of the result will not change. Server response time, the same pages with the page cache off and on: Home page – 52.7 ms without, 15.1 ms with, 71% faster WooCommerce shop – 45.4 ms without, 14.8 ms with, 67% faster A 110 KB article – 43.0 ms without, 15.1 ms with, 65% faster A 98 KB page – 41.0 ms without, 14.9 ms with, 64% faster A product category – 41.3 ms without, 15.1 ms with, 63% faster The interesting part is not the percentage, it is that the cached figure barely moves. Serving a stored file costs the same whether the page was cheap or expensive to build, so the saving grows with the size of your site rather than with the power of your server. The heaviest page in the test is the one that gained most. It also changes how much traffic your hosting can take at once. In the same test the server went from serving about 40 visits a second to more than 210, five times as many, on exactly the same plan. That is what keeps a small site standing up when one of your posts does well. TWO THINGS IN ONE PLUGIN 1. Performance optimizations (on by default) Automatic Critical CSS inlined in the head (optional experimental deferral of non-critical CSS) JavaScript defer parsing with smart dependency handling Image loading attributes safety net: lazy loading, decoding=async and fetchpriority for images that bypass core Automatic image dimensions for better CLS scores (including picture elements) Resource hints: preconnect and DNS prefetch for common third-party origins Theme stylesheet, critical fonts and logo preloading for a faster LCP Google Fonts display=swap Google Fonts local hosting: serve the fonts your theme uses from your own server, GDPR-friendly with a silent fallback to the Google CDN (opt-in) Selective third-party loading: WooCommerce, Contact Form 7, block library, Slider Revolution, TablePress, Smash Balloon, Formidable Forms and Everest Forms assets only load where they are used (opt-in) RSS feed optimization (cache headers and item limit) Server rules in .htaccess: browser caching with a configurable lifetime for media, for styles and scripts and for fonts, GZIP and Brotli compression, immutable cache headers, CORS for fonts and keep-alive (master switch plus per-feature toggles) Database maintenance: daily expired-transient cleanup and safe query optimizations Page cache: store each page on disk and serve it to anonymous visitors without building it again, with automatic purging, gzip precompression and a status panel that says whether it is working (opt-in, in its own tab) 2. Put WordPress on a diet (risk-based, opt-in) Light (safe for any site): emojis, RSD/WLW tags, shortlinks, self-pingbacks, comment pagination, and more Moderate (evaluate first): oEmbed, jQuery Migrate, Dashicons on the frontend, Global Styles and Duotone, remote block patterns, avatars and Gravatar, comment threading, and more Strict (site-specific): granular RSS feed control, Heartbeat API mode, post revisions and autosave, disable comments, XML sitemap, native lazy loading/fetchpriority, content types, selective loading for WooCommerce, Contact Form 7, block assets, Slider Revolution, TablePress, Smash Balloon, Formidable Forms and Everest Forms, and more Widgets: dashboard widgets (including third-party ones from Yoast, WooCommerce, Elementor, Jetpack, Wordfence, Rank Math, Gravity Forms), classic sidebar widgets, block-editor widgets and the Customizer Emails: silence the automatic emails WordPress sends on its own, grouped by area: auto-update results for core, plugins and themes (plus the new-version notice), comment moderation and new-comment notices, and new user, password and email-change notices, plus toggles for the admin email verification prompt and post-by-email.

The module is wc, cf7, formidable, everest_forms or revslider dietpress_selective_{module}_styles / dietpress_selective_{module}_scripts – Adjust the handles removed by each module dietpress_selective_page_hides_content – Mark a page as rendering content the content scan cannot reach, so no module removes anything (this is what handles Elementor) dietpress_selective_is_wc_page – Override the WooCommerce page detection of selective loading dietpress_selective_wc_keep_cart_fragments – Keep the cart fragments script when your theme has a hand-coded mini-cart dietpress_selective_cf7_has_form – Mark pages that load a Contact Form 7 form dynamically dietpress_selective_blocks_dequeue – Override the block library dequeue decision dietpress_selective_everest_forms_dequeue_dashicons – Keep Dashicons when another plugin enqueues it directly dietpress_native_sitemap_in_use – Tell DietPress your plugin builds on the native WordPress sitemap, so the option that removes it becomes unavailable dietpress_cache_bypass – Keep the current page out of the page cache dietpress_cache_bypass_cookies – Adjust the cookie name prefixes that make a visitor uncacheable dietpress_cache_ignored_params – Adjust the query parameters that do not change the page dietpress_cache_exclude_urls – Adjust the excluded URL patterns dietpress_cache_post_urls – Adjust the URLs purged along with a post Compatible with: Well-coded themes and page builders (Divi, Elementor, Beaver Builder, Bricks Gutenberg) Cache plugins (WP Rocket, LiteSpeed Cache, W3 Total Cache, WP Super Cache, etc.). The one exception is the optional page cache module, which will not run beside another page cache and says so; everything else in DietPress works alongside them as it always has Security plugins (DietPress focuses on performance and deliberately leaves security to them; we recommend our free Vigilant) CDNs (Cloudflare, StackPath, KeyCDN, etc.) thanks to CORS and Vary headers WordPress Multisite (except the optional page cache module, which does not support it yet) HOW TO VERIFY THE OPTIMIZATIONS Cache rules: check your .htaccess for a block marked # BEGIN DietPress with immutable Cache-Control headers Logo preload: view page source and look for pointing to your logo Critical CSS: view source and look for in the head Compression: test at giftofspeed.com/gzip-test Always measure with tools like Google PageSpeed, GTMetrix or WebPageTest, and run each test at least twice to account for caching.
