AVIF goes even further \u2014 delivering files up to 50% smaller<\/strong> than JPEG and 20% smaller<\/strong> than WebP. By serving these formats automatically to supported browsers, your site loads dramatically faster with zero manual effort.<\/p>\n\n Version 2.0.0 is a major release<\/strong> introducing AVIF support, a redesigned dashboard, live optimization logs, server-level rewrite rules, system diagnostics, and much more.<\/p>\n\n\n\n Google's Core Web Vitals (LCP, FID, CLS) are directly impacted by image delivery performance. Large, unoptimized images are the #1 cause of slow page loads and poor PageSpeed Insights scores. WebPressor solves this automatically by:<\/p>\n\n \ud83d\udd39 WebP Conversion<\/strong> \u2014 Automatically convert all JPEG and PNG images to WebP format with GD library\n\ud83d\udd39 AVIF Conversion<\/strong> (New in 2.0)<\/em> \u2014 Generate AVIF images for the smallest possible file sizes (PHP 8.1+ with GD AVIF support required)\n\ud83d\udd39 Bulk Optimizer<\/strong> \u2014 Process your entire Media Library in batches with a real-time live console log\n\ud83d\udd39 Auto-Convert on Upload<\/strong> \u2014 Instantly convert new images as they are added to the Media Library\n\ud83d\udd39 Smart Browser Detection<\/strong> \u2014 Serve AVIF to AVIF-capable browsers, WebP to WebP browsers, and original images to legacy browsers\n\ud83d\udd39 Two Delivery Methods<\/strong> \u2014 Choose between HTML URL replacement or server-level HTML Alteration (Default):<\/strong>\nWebPressor replaces image Server Rewrite Rules (.htaccess):<\/strong>\nFor Apache and LiteSpeed servers, WebPressor writes redirect rules directly into \ud83d\udd39 Documentation<\/a>\n\ud83d\udd39 Support Forum<\/a>\n\ud83d\udd39 GitHub Repository<\/a><\/p>\n\n\n\n This plugin's JavaScript\/CSS assets are minified for production. The original React source code and build tools are available publicly on GitHub.<\/p>\n\n Repository:<\/strong>\nhttps:\/\/github.com\/TechbyshOrg\/tbs-webpressor.git<\/p>\n\n How to build:<\/strong>\n1. Clone the repo: Installation of WebPressor can be done in two ways:<\/p>\n\n Option 1 \u2013 Install from WordPress Dashboard (Recommended)<\/strong><\/p>\n\n Option 2 \u2013 Manual Upload<\/strong><\/p>\n\n No. WebPressor never modifies or deletes<\/strong> your original JPEG and PNG files. It generates separate WebPressor converts JPEG<\/strong> ( No! Simply install and activate the plugin, go to WebPressor \u2192 Dashboard<\/strong>, and click Start Optimization<\/strong>. The defaults are pre-configured for the best balance of quality and file size savings.<\/p><\/dd>\n WebP<\/strong> is Google's image format offering 25\u201335% smaller files than JPEG and is supported by 97%+ of browsers. AVIF<\/strong> is a newer AV1-based format offering 40\u201350% smaller files than JPEG and is supported by 80%+ of modern browsers. WebPressor automatically serves AVIF to browsers that support it, falls back to WebP for others, and falls back to the original image for legacy browsers.<\/p><\/dd>\n Positively! Faster page loads from smaller images directly improve your Core Web Vitals scores (LCP in particular), which are a ranking factor in Google's algorithm. WebPressor also passes Google's PageSpeed Insights \"Serve images in next-gen formats\" audit.<\/p><\/dd>\n HTML Alteration<\/strong> modifies image URLs inside page HTML content on-the-fly using PHP. It works everywhere but only affects images in page content and widget text.<\/p>\n\n Server Rewrite Rules<\/strong> add Apache\/LiteSpeed Yes! WebPressor converts all registered WordPress image sizes, including WooCommerce product thumbnails, gallery images, and the Yes. WebPressor is fully compatible with Elementor, Divi, Avada, Beaver Builder, the WordPress block editor (Gutenberg), and all other major page builders. When using the HTML delivery method, all images in content areas are replaced. For background images set through page builders, the Server Rewrite Rules delivery method is recommended.<\/p><\/dd>\n Use the Bulk Optimizer<\/strong> on the Dashboard to process your entire existing Media Library. The plugin will convert all previously uploaded images in batches and display real-time progress and savings in the live console log.<\/p><\/dd>\n Enable the \"Automatically convert images on upload\"<\/strong> option in the Settings tab. When enabled, any new image uploaded to the Media Library will be automatically converted in the background.<\/p><\/dd>\n Yes. The Settings tab provides independent quality sliders for WebP (recommended: 75\u201385) and AVIF (recommended: 60\u201370). You can also choose between Lossy<\/strong> mode (recommended for maximum size savings) and Lossless<\/strong> mode (100% quality, larger files).<\/p><\/dd>\n Yes. Click the Reset Conversions<\/strong> button on the Dashboard. This will delete all generated No. Bulk conversion uses AJAX-based batch processing that runs in the background without blocking your admin interface. You can continue using WordPress normally while the optimizer runs.<\/p><\/dd>\n Yes, WebPressor is compatible with WordPress Multisite installations.<\/p><\/dd>\n WebPressor converts images stored in the local filesystem ( Yes. WebPressor is compatible with WP Rocket, W3 Total Cache, WP Super Cache, LiteSpeed Cache, Autoptimize, and other popular caching plugins. After running the bulk optimizer, clear your cache to ensure visitors receive the new optimized images.<\/p><\/dd>\n WebPressor detects browser support using the HTTP .htaccess<\/code> rewrite rules, and configure auto-conversion on upload.<\/p>","3":".htaccess<\/code> rewrite rules, and configure auto-conversion on upload.<\/p>"},{"src":"https:\/\/ps.w.org\/webpressor-webp-image-converter-optimizer\/assets\/screenshot-3.png?rev=3568594","caption":"\ud83d\ude80 Why Image Optimization Matters<\/h3>\n\n

Does WebPressor replace or delete my original images?<\/h3><\/dt>\n
.webp<\/code> and .avif<\/code> versions alongside the originals and serves them conditionally based on what the visitor's browser supports. You can reset and delete all generated files at any time from the Dashboard.<\/p><\/dd>\nWhat image formats does WebPressor convert?<\/h3><\/dt>\n
.jpg<\/code>, .jpeg<\/code>) and PNG<\/strong> (.png<\/code>) images. It converts the full-size original plus all registered WordPress thumbnail sizes (such as thumbnail<\/code>, medium<\/code>, large<\/code>, medium_large<\/code>, and custom theme sizes).<\/p><\/dd>\nDo I need to configure anything to get started?<\/h3><\/dt>\n

What is the difference between WebP and AVIF?<\/h3><\/dt>\n
Will this plugin affect my site's SEO?<\/h3><\/dt>\n
What is the difference between HTML Alteration and Server Rewrite Rules?<\/h3><\/dt>\n
.htaccess<\/code> directives that intercept image requests at the server level before PHP even runs. This method also handles background CSS images, JavaScript-loaded images, and slider images \u2014 making it more thorough and slightly faster.<\/p><\/dd>\nDoes the plugin work with WooCommerce product images?<\/h3><\/dt>\n
woocommerce_thumbnail<\/code> size. All image sizes are optimized during bulk conversion.<\/p><\/dd>\nDoes it work with page builders like Elementor, Divi, or Gutenberg?<\/h3><\/dt>\n

How do I convert newly uploaded images automatically?<\/h3><\/dt>\n
Can I control the compression quality?<\/h3><\/dt>\n
Can I undo the conversions and restore my original images?<\/h3><\/dt>\n
.webp<\/code> and .avif<\/code> files and reset the statistics, leaving your original images completely intact.<\/p><\/dd>\nWill the plugin slow down my WordPress admin?<\/h3><\/dt>\n
Is WebPressor compatible with WordPress Multisite?<\/h3><\/dt>\n
Does WebPressor work with CDN or object storage?<\/h3><\/dt>\n
\/wp-content\/uploads\/<\/code>). If you use a CDN, the CDN will automatically serve the WebP\/AVIF files once they have been generated and your CDN is configured to cache those file types. If images are stored externally (e.g., Amazon S3 via a cloud offload plugin), local conversion may not be possible \u2014 CDN-level WebP conversion would be needed instead.<\/p><\/dd>\nDoes WebPressor work with caching plugins?<\/h3><\/dt>\n
What happens if a visitor's browser does not support WebP or AVIF?<\/h3><\/dt>\n
Accept<\/code> request header. Browsers that do not declare support for image\/avif<\/code> or image\/webp<\/code> will receive the original JPEG or PNG image automatically \u2014 there is zero impact on compatibility.<\/p>\n\n<\/dd>\n\n<\/dl>\n\n\n2.0.0<\/h4>\n\n
