This plugin helps to increase site speed, and helps to improve scores in Google’s Pagespeed Insights tool by addressing the common recommendation “Serve next-gen image formats”.
For the best speeds, Google recommends using new image formats such as .webp, which offer smaller file sizes than common formats such as .jpg or .png with no visible loss in quality. However, not all internet browsers support the .wepb image format, so only using that format would result in broken images in older browsers.
This plugin addresses that problem, and allows your site to use .webp images when it can. This plugin will convert images from .jpg or .png automatically, and save .webp versions of the image alongside the original. When a user visits the site in a compatible browser, they will be shown the .webp versions of all images, making your site load faster and improving your scores in Google Pagespeed Insights. Users on older browsers that aren’t compatible with .webp images will be shown the .jpg or .png versions of the images instead.
When first installing the plugin, run the Bulk Converter to convert all your existing images. See the Installation section for instructions.
After installation, any .jpg or .png image uploaded to the Media Library will be automatically converted.
<h3>Settings</h3>
<ul>
<li>
Conversion quality – Controls the level of compression on the generated .webp images. The lower the value, the smaller the file size of the generated images, but the more chance there is of a visual degradation of quality. The quality value to be entered is a percentage – by default, this is set at 80%. Most users won’t need to change this.
</li>
<li>
HTML Output Buffering – This allows the plugin to perform a find-and-replace on the HTML that WordPress has generated for output to the browser to replace image tags. This tends to perform the image tag replacement more reliably, but can cause issues with some themes. Users are advised to have this setting turned on, but they should check that the site is displaying as it should, and turn this option off if any issues arise.
</li>
<li>
Exclude pages from HTML output buffering – To specify pages that should be excluded from the HTML Output Buffering settings
</li>
<li>
Lazy loading – This improves the site speed further by not loading images that are further down the page until the user has scrolled down to them. This saves time downloading images that the user hasn’t got to yet, or might not get to at all. Users are advised to have this setting turned on, but they should check that the site is displaying as it should, and turn this option off if any issues arise.
</li>
<li>
Exclude image classes from lazy-loading – To specify images, by class name, that should not have the lazy-loading applied
</li>
</ul>
<h3>Developers</h3>
If using Simple Webp Images with your custom themes or plugins, there’s a couple of filters you can use, as below.
<ul>
<li><code>simple-webp-images-exclude-from-output-buffering</code> filter</li>
</ul>
Use this to exclude pages or posts from the HTML output buffering via <code>apply_filters</code>, using any critera you need. Call the filter, run any checks you need, and return ‘true’ to exclude the current page or post from the buffering. 
Example:
<pre><code>apply_filters( 'simple-webp-images-exclude-from-output-buffering', 'exclude_page_with_id_100_from_output_buffering' );
function exclude_page_with_id_100_from_output_buffering( $is_excluded ) {
 if( get_the_id() == 100 ) {
 return true;
 }

 return false;
}
</code></pre>
The example code could be placed in your <code>functions.php</code> file.
<ul>

Speed Booster Pack is maintained & operated by <a href="https://optimocha.com/" rel="nofollow ugc">Optimocha</a>, a company that offers special speed optimization services filled with people who obsess about speed!
<h3>Benefits of Speed Booster Pack</h3>
Each second of delay can cause up to 20% loss in conversion rates (<a href="https://web.dev/articles/why-speed-matters" rel="nofollow ugc">source: Google</a>). “Conversion” means converting visitors to something more than a “visitor”: leads, customers, subscribers, followers… you name it.
You might lose more than half of your visitors if your website loads slower than three seconds! (<a href="https://www.blog.google/products/admanager/the-need-for-mobile-speed/" rel="nofollow ugc">source: Google again</a>) More than half of your potential customers might get back to the search results page and navigate to your competitor. This is a huge problem, and it’s hugely overlooked among other SEO-related concerns. People don’t realize how important speed is, in the eyes of search engines.
That’s where Speed Booster Pack comes in: With its ever-evolving codebase, Speed Booster Pack aims to increase your site performance, page load times and PageSpeed (Lighthouse) scores! Optimocha, the company behind Speed Booster Pack, has a team with a pathological obsession for speed; so you can be sure that your site will be in good hands.
<h3>How to optimize PageSpeed Core Web Vitals metrics with Speed Booster Pack</h3>
With our huge set of features, of course!
⭐ Core Web Vitals: Speed Booster Pack is made to improve your <a href="https://web.dev/articles/lcp" rel="nofollow ugc">Largest Contentful Paint (LCP)</a>, <a href="https://web.dev/articles/inp" rel="nofollow ugc">Interaction to Next Paint (INP)</a> and <a href="https://web.dev/articles/cls" rel="nofollow ugc">Cumulative Layout Shift (CLS)</a> metrics, which are also known together as <a href="https://web.dev/articles/vitals" rel="nofollow ugc">Core Web Vitals</a>. (The <a href="https://web.dev/articles/fid" rel="nofollow ugc">First Input Delay (FID)</a> metric is being replaced by INP, but Speed Booster Pack also improves FID and its lab counterpart, <a href="https://web.dev/articles/tbt/" rel="nofollow ugc">Total Blocking Time (TBT)</a>.) With the right configuration, you can get your PageSpeed scores higher than ever! 
⭐ Caching: Cache your pages into static HTML files, reduce database queries, get a faster website almost immediately. What’s not to love about caching? 
⭐ Optimize Google Fonts: Did you know that there are better ways to load Google fonts? We like to brag about finding one of the best ways. 
⭐ Lazy Load: It’s a disheartening issue that page speed tools encourage laziness… Just kidding, we love being lazy. And search engines will love your pages when you enable lazy loading for images, videos and iframes (except for the above-the-fold stuff, trust us). 
⭐ Optimize JavaScript: You know that totally-not-cryptic “Remove Render-Blocking JavaScript” recommendation? Speed Booster Pack can help defer them all until after the whole HTML is rendered, or at least move all scripts to footer. Works like a charm. 
⭐ Optimize CSS: Who needs all those different CSS files when you can inline them all into your page source? Especially when your CSS footprint is so small? Moreover, you can use the “<a href="https://web.dev/articles/extract-critical-css" rel="nofollow ugc">Critical CSS</a>” feature to essentially lazy-load all your CSS except for the CSS for above-the-fold. 
⭐ Preload Assets: Have some fonts that load in all your pages, or a script, or some CSS files? Preloading them will help modern browsers serve your pages way faster! 
⭐ WooCommerce Optimizations: Disable cart fragments, change Action Scheduler’s retention period, disable things like WooCommerce Marketing and WooCommerce Analytics… and more to come! 
⭐ Dequeue Core Scripts/Styles: Dashicons, jQuery Migrate, emoji script, post embed script… If you don’t need them, you can now choose to prevent them from loading in the first place… which can get you to the first place on your Google SERPs. 
⭐ Localize Google Analytics & Tag Manager: Tracker scripts aren’t the worst things that’ll slow your pages down, but they cause the most “recommendations”. Localizing Google Analytics and/or Google Tag Manager is a good idea to speed up your website then, right? Right? 
⭐ Enable CDN: Integrate your content delivery network to your website by rewriting all static asset URLs with your CDN domain. 
⭐ Cloudflare & Sucuri Integration: Connect to your Cloudflare or Sucuri account so you can clear your cache every time your page cache is cleared. 
⭐ Declutter HEAD: Do you think all that useless junk in your should be gone? Us too! You know what they say: A clear works faster. 
⭐ Other Features: Minify HTML, enable instant.page, trim query strings, disable self pingbacks, optimize the Heartbeat API, set a limit for post revisions, change autosave interval… Did we forget anything?
