3. DC jSitemap

   This location is fully compatible with Google Search Console and most SEO tools.

   ⚙️ How It Works

   1. On each frontend request, the plugin checks if sitemap.xml exists.
   2. If it doesn’t exist → it generates a fresh sitemap.
   3. If it exists → the plugin checks the file age.
   4. If older than 24 hours → it regenerates the sitemap.
   5. Otherwise → nothing happens (fast execution).

   This ensures extremely low overhead and full automation.

4. DC jWEBP

   How to optimize images on a Joomla website – ready-to-use tool
   DC JWebP is a free, lightweight and fully automatic system plugin for Joomla that optimizes images by converting them to the modern WebP format.
   After enabling the plugin, JPG and PNG images are automatically converted to WebP, replaced directly in the generated HTML and enhanced with native lazy loading. No configuration is required to get started – the plugin works immediately after activation and improves website performance without modifying templates or database records.

   Main features of DC JWebP
   DC JWebP focuses on one task: making Joomla websites faster by optimizing images globally.
   Key features include automatic conversion of JPG and PNG images to WebP format, replacing image paths across the entire HTML output (including images generated by page builders and inline styles), support for both standard image tags and background-image declarations, and native lazy loading using the loading="lazy" attribute without JavaScript.
   The plugin supports both local image paths and full URLs, works with Joomla 5 and 6, and is fully compatible with PHP 8.1, 8.2 and 8.3. It is extremely lightweight and does not rely on any external libraries or frameworks. DC JWebP does not modify the database and does not require any changes in the template files.

   Configuration options
   DC JWebP includes a simple configuration panel in the Joomla administrator area.
   Available options allow you to define the WebP image quality (from 0 to 100), exclude selected folders from processing, enable or disable native lazy loading, and prepare the plugin for further extensions such as srcset or picture support in future versions.
   All settings are optional – the plugin works out of the box with sensible defaults.

   Why WebP format matters
   Images are often the heaviest part of a website and can account for 50–70% of total page weight. Google strongly recommends using next-generation image formats such as WebP to improve loading speed and Core Web Vitals.
   WebP allows you to maintain very similar visual quality while significantly reducing file size. In practice, this means faster page load times on mobile devices, better Google PageSpeed scores, lower bandwidth usage and improved overall responsiveness.
   According to Google PageSpeed recommendations, WebP can reduce image size by 25–35% compared to JPG and by more than 80% compared to PNG for non-transparent images.
   Reducing image size has a direct impact on SEO, performance and conversion rates, especially on mobile connections.

   How DC JWebP works internally
   DC JWebP is designed to work efficiently without blocking Joomla rendering.
   The plugin runs during the onAfterRender event, after the page HTML has been fully generated. It scans the final HTML output, detects image tags and background-image declarations, and replaces image paths with WebP versions when available.
   Images are converted only once, during the first request. Subsequent page views reuse the already generated WebP files, which keeps server load minimal. Native lazy loading is applied automatically without any JavaScript execution.
   As a result, pages load faster, use less data and achieve better PageSpeed scores without affecting site stability.

   Compatibility
   DC JWebP is fully compatible with Joomla 5 and Joomla 6 and works correctly with Joomla 4 as well. It supports PHP versions from 8.1 to 8.3.
   The plugin works with popular page builders and templates such as SP Page Builder, Helix Ultimate, YOOtheme and any custom or Bootstrap-based templates. Since it operates on the final HTML output, it remains independent of the framework or builder used.

   Frequently Asked Questions
   Does the plugin overwrite original images? No. Original JPG and PNG files remain unchanged. WebP images are created as separate files.
   Are WebP images generated on every request? No. Conversion happens only on the first request. After that, existing WebP files are reused.
   Does the plugin add lazy loading? Yes. Native loading="lazy" is added automatically without JavaScript.
   Does it work with background images? Yes. Inline background-image declarations are detected and replaced.
   Does it require JavaScript? No. DC JWebP works entirely on the PHP side.

5. DC jVideo

   DC jVideo is a lightweight content plugin for Joomla 5 and Joomla 6 that allows you to embed video content in a clean, controlled and modern way using a simple shortcode.

   Embedding video in Joomla is still often problematic. Editors generate heavy iframe code, layouts break easily, and you have very limited control over user experience. DC jVideo was created to solve exactly these problems by giving you full control over how and where video appears on the page.

   The plugin works as a content plugin and uses a simple shortcode instead of editor buttons or visual builders. This makes it predictable, clean and easy to use in any Joomla article.

   DC jVideo supports inline video embedding directly inside article content. With a single shortcode, a video can be displayed responsively inside the text without breaking the layout. The video scales correctly, keeps its aspect ratio and works well on both desktop and mobile devices. The default preload behavior is optimized for performance and SEO.

   In addition to inline playback, DC jVideo offers a lightbox mode with a custom animation. When lightbox mode is enabled, the article displays a button instead of the video. After clicking the button, the screen is covered by an animated backdrop that expands from a small circle into a full-screen overlay. The video then slides in from the bottom with a smooth bounce animation. The lightbox can be closed using the close button, the ESC key or by clicking outside the video area.

   DC jVideo automatically detects the video source and renders it appropriately. Supported sources include local HTML5 video files such as MP4 (optionally WebM), YouTube videos and Vimeo videos. The user does not need to specify the video type manually. The plugin recognizes the source based on the provided URL and handles everything automatically.

   For local HTML5 videos, DC jVideo provides full control over the video source without using external iframes. For YouTube and Vimeo, videos are embedded using clean iframe players with autoplay support in lightbox mode.

   The plugin does not depend on jQuery. It is built entirely using modern, vanilla JavaScript. This makes it fully compatible with Joomla 5 and Joomla 6, avoids conflicts with templates and reduces unnecessary overhead.

   DC jVideo focuses heavily on user experience. When the lightbox is open, scrolling of the page behind it is blocked. All dynamically created elements are removed from the DOM after closing the lightbox, preventing memory leaks or leftover elements.

   The plugin is designed for developers and site builders who want full control over video presentation. It is ideal for technical blogs, product pages, landing pages with video content and any Joomla site where UX matters more than simply pasting an iframe.

   Shortcode usage examples:

   Inline video playback:
   {video href="https://extensions.joomla.org/images/video/example.mp4"}

   Lightbox video playback:
   {video href="https://extensions.joomla.org/images/video/example.mp4" mode="lightbox" anchor="Watch video" poster="/images/video/example.png"}

   YouTube example:
   {video href="https://www.youtube.com/watch?v=VIDEO_ID
   " mode="lightbox" anchor="Watch demo"}

   Vimeo example:
   {video href="https://vimeo.com/VIDEO_ID
   " mode="lightbox" anchor="Watch video"}

   DC jVideo is fully compatible with Joomla 5 and Joomla 6 and does not use deprecated APIs.

   The plugin can be installed using the standard Joomla extension installer. You can download it from the Design Cart website or from GitHub.
