## Description
**Easy Optimizer** is a free, all-in-one WordPress performance plugin that replaces
the 3–5 speed plugins most sites run today. One plugin. One dashboard. No premium
upsells for core features.
Every toggle maps to a specific Google Lighthouse recommendation — enable it, save,
and your Core Web Vitals (LCP, CLS, INP) improve immediately. Features you don’t
enable never touch your page load.
#### Full Page Cache
Static HTML served without PHP or database queries. Apache .htaccess mode delivers
pages in under 1ms; PHP fallback works on Nginx, LiteSpeed and OpenLiteSpeed. Separate
mobile/desktop cache, logged-in user caching with per-role variants, sitemap-based
preloading, browser caching headers, and Gzip/Brotli compression — all automatic.
Exclude URLs, cookies, query parameters, and tracking params (utm_source, fbclid)
so one cached page serves all campaign links.
#### Remove Unused CSS
Tackles the highest-impact PageSpeed audit head-on. The plugin scans each page type,
strips every CSS selector the DOM doesn’t use, and outputs a slim stylesheet with
only what’s needed. You choose how original stylesheets are handled: delay until
interaction (safest), async load, or full removal (advanced). Used CSS can be inlined
or served as an external file. Separate mobile/desktop generation ensures themes
like Astra, Kadence and GeneratePress keep their responsive classes intact. Auto-
clears on post save and theme switch.
#### Delay & Defer JavaScript
Two methods to cut Total Blocking Time and improve INP. **Delay until interaction**
holds all scripts until the visitor’s first mouse, keyboard, touch or scroll event—
best Lighthouse scores. **Defer** uses the browser’s native defer attribute — scripts
download in parallel and run after HTML parsing. jQuery excluded by default. Exclude
by keyword, URL fragment or page path. Inline scripts can be externalized and delayed
too.
#### Lazy Load Images, Iframes, Videos & Backgrounds
Offscreen media loads only when needed — images (WebP, AVIF, SVG), iframes (YouTube,
Maps, embeds), videos and CSS background images. Uses WordPress core’s WP_HTML_Processor
for accurate parsing that skips noscript tags and the admin bar. Set “Exclude First
N Images” to keep hero images eager. Auto-adds missing width/height attributes by
reading image file headers — fixes the “Image elements do not have explicit width
and height” audit and prevents CLS.
#### Automatic LCP Preload
Zero configuration. A lightweight PerformanceObserver beacon detects the LCP image
on first visit. Every visit after that gets an automatic ``
with `fetchpriority="high"` in the head and `loading="eager"` on the img tag. Results
are stored per URL type and viewport (mobile/desktop) with a 30-day refresh.
#### Prefetch Pages
Makes your site feel like a single-page app. The EasyOptLink engine watches for
in-viewport and hovered links, then pre-fetches or pre-renders them using the Speculation
Rules API. When visitors click, the page is already cached in their browser. Four
eagerness levels (conservative immediate), configurable throttle and limit, plus
URL and CSS selector exclusions.
#### Font Optimization
Adds `font-display: swap` to every @font-face — Google Fonts, inline styles, external
stylesheets. Optional lazy-load font stylesheets defers font loading entirely, further
cutting render-blocking resources.
#### Image CDN
Rewrites image URLs to the ShortPixel CDN for automatic WebP/AVIF conversion and
compression. Works with img src, srcset, inline background-image CSS and Elementor
background images. No API key needed for the default tier. Exclude images by URL
fragment.
#### Bloat Removal — 15 Toggles
Disable what your site doesn’t need: emoji scripts, oEmbed, XML-RPC, jQuery Migrate,
version meta generator, RSD/WLW links, shortlinks, RSS feeds, self-pingbacks, REST
API for logged-out visitors (smart allowlist for CF7, WPForms, Gravity Forms, WooCommerce,
Gutenberg), Heartbeat API, WooCommerce cart fragments, Application Passwords, Dashicons
for non-logged-in users, and Gutenberg Block Library CSS. Each toggle is independent.
#### Database Cleanup & Optimization
Remove revisions, auto-drafts, trashed posts, spam/trashed comments, expired or
all transients, and optimize tables. Schedule daily, weekly or monthly. Automatic
pre-cleanup snapshots let you restore if needed. The Autoload Health auditor shows
total autoload size, lists the largest autoloaded options, and lets you toggle autoload
off — with one-click re-enable and core option protection.
#### Cloudflare Integration
When Easy Optimizer clears its page cache, Cloudflare edge cache purges automatically.
Supports tag-based purge (Enterprise) and full zone purge (all plans). Test your
API connection before saving.
#### Hosting Auto-Purge
Auto-detects and integrates with Kinsta, WP Engine, SiteGround, Cloudways, GridPane,
RunCloud, SpinupWP, Rocket.net and WordPress.com. Server-level cache purges alongside
Easy Optimizer’s cache automatically.
#### Heartbeat & Cron Manager
Control where Heartbeat runs and set custom frequency (15–300s). Throttle WP-Cron
to every 2, 5 or 10 minutes without touching wp-config.php. View all scheduled cron
events, run them manually or delete them.
#### Accessibility Fixes
Automatically fixes eight common Lighthouse accessibility failures using WordPress
core’s WP_HTML_Tag_Processor:
* Adds `aria-label` to inputs missing associated labels
* Adds `aria-label` to links with no discernible name
* Adds `aria-label` to buttons with no accessible name
* Strips `user-scalable=no` and `maximum-scale` restrictions from viewport meta
* Adds `aria-label` to elements with interactive ARIA roles but no accessible name
* Adds `title` to iframes/frames missing both title and aria-label
* Adds `aria-label` to progressbar elements without accessible names
* Resets `tabindex` values greater than 0 back to 0
#### SEO Fixes
* Rewrites anchor tags with missing, empty or `javascript:void(0)` hrefs to `href
="#"` — fixes “Links are not crawlable”
* Generates alt text from image title or filename when alt is completely missing—
fixes “Image elements do not have [alt] attributes”
#### Modern Admin Dashboard
Clean, tabbed settings interface. Caching, JavaScript, CSS, Lazy Load, Preload LCP,
Prefetch Pages, Fonts, Image CDN, Bloat Removal, Cloudflare, Database Cleanup, Autoload
Health, Heartbeat & Cron, Accessibility & SEO, and Settings — each in its own panel.
Real-time cache stats, preload progress, quick-action buttons, collapsible help
sections, and JSON import/export for easy migration.
#### PageSpeed Insights & Lighthouse Recommendations Addressed
* Reduce initial server response time (TTFB) — page cache
* Eliminate render-blocking resources — unused CSS removal, font-display:swap
* Reduce unused CSS — per-page-type used CSS generation
* Reduce unused JavaScript — delay JS until interaction
* Minimize main-thread work — delay and defer JavaScript
* Defer offscreen images — lazy load images
* Serve images in next-gen formats — ShortPixel CDN (WebP/AVIF)
* Properly size images — add missing width and height
* Image elements do not have explicit width and height — auto-dimension injection
* Preload Largest Contentful Paint image — automatic LCP detection and preload
* Ensure text remains visible during webfont load — font-display:swap
* Serve static assets with an efficient cache policy — browser caching headers
* Enable text compression — Gzip/Brotli rules
* Form elements do not have associated labels — accessibility fix
* Links do not have a discernible name — accessibility fix
* Buttons do not have an accessible name — accessibility fix
* [user-scalable=”no”] in viewport or [maximum-scale] < 5 — viewport fix
* Frame or iframe elements do not have a title — accessibility fix
* ARIA progressbar elements do not have accessible names — accessibility fix
* Some elements have a [tabindex] value greater than 0 — tabindex fix
* Links are not crawlable — SEO fix
* Image elements do not have [alt] attributes — SEO fix

### External Services
This plugin optionally rewrites image URLs to ShortPixel’s CDN to serve optimized
images:
* Service: ShortPixel CDN (https://cdn.shortpixel.ai/)
* What it does: When “Image CDN” is enabled, image URLs are rewritten so visitors’
browsers request images from ShortPixel’s CDN, enabling WebP/AVIF delivery.
* What data is sent: Only the image URL. No site data or personal information is
transmitted.
* Links: [ShortPixel Privacy Policy](https://shortpixel.com/privacy) | [ShortPixel Terms of Service](https://shortpixel.com/terms-of-service)
### Privacy
Easy Optimizer includes optional anonymous usage tracking to help improve the plugin.
Disabled by default — only enabled after explicit opt-in. No personal data, site
content, emails, IPs, usernames or passwords are ever collected.

## Installation
1. Install via **Plugins Add New** and search “Easy Optimizer”, or upload to `/wp-
content/plugins/easy-optimizer/`.
2. Activate the plugin.
3. Go to **Easy Optimizer** in the admin sidebar.
4. Enable Page Cache and Remove Unused CSS first — they have the biggest impact.
5. Save. The cache preloader starts warming your site automatically.
## FAQ
### Does this replace WP Rocket, LiteSpeed Cache or W3 Total Cache?
Yes — page caching, unused CSS, delay JS, lazy loading, LCP preload, font optimization,
image CDN, database cleanup, bloat removal, accessibility and SEO fixes all in one
free plugin. Disable other caching plugins before enabling the page cache.
### Does it work with WooCommerce?
Fully. Cart, checkout and my-account pages are automatically excluded from all optimization
modules. Cart fragments can be disabled separately from the Bloat Removal tab.
### Will Delay JavaScript break my site?
Most sites work without issues. jQuery is excluded by default. If something breaks,
add the script name to the exclusion list or switch to the safer Defer method.
### Can I use this with Cloudflare?
Yes. Add your API token and Zone ID in the Cloudflare tab. Cache purges sync automatically.
### Does it support multisite?
Works on individual sites within a multisite network. Network-wide activation is
in testing.
### How do I migrate settings between sites?
Export settings as JSON from the Settings tab, then import on the destination site.
### What’s the best starting configuration?
Enable Page Cache, Remove Unused CSS, Delay JavaScript, Lazy Load Images, Preload
LCP and Font Display Swap. Then turn on the accessibility and SEO toggles relevant
to your site.
## Reviews
### [Nice speed optimization plugin](https://wordpress.org/support/topic/nice-speed-optimization-plugin/)
[yolandeadme](https://profiles.wordpress.org/yolandeadme/) May 24, 2026
I like the overall plugin design and user interface. The settings are easy to understand
and configure. One thing I really liked is that the plugin provides an unused CSS
optimization feature for free, which is usually available only in premium plugins.
It also helped improve performance scores and is a good and free alternative of
wp rocket and flyingpress for users looking for a speed optimization plugin.
### [not good](https://wordpress.org/support/topic/not-good-229/)
[goobola](https://profiles.wordpress.org/goobola/) March 11, 2024
after installing this plugin google search give me Server error (5xx) and i’m not
able to index my page but after removing this plugin my problem is solved. so think
before you install this.
### [The only one which worked](https://wordpress.org/support/topic/the-only-one-which-worked/)
[MarkJ](https://profiles.wordpress.org/forusak/) November 5, 2023
As I was optimizing a badly coded theme, where no lazyloading plugin wanted to work,
I am giving 5* because finally this one worked.
### [Simple and best](https://wordpress.org/support/topic/simple-and-best-21/)
