Frequently Asked Questions
The WebP Converter plugin automatically converts your website images to modern formats (WebP and AVIF), reducing file sizes by up to 80% without compromising visual quality. This results in faster page load times, improved Core Web Vitals scores, and better SEO rankings. The plugin supports Joomla 4.x, 5.x, and 6.x with enterprise-grade features for large-scale deployments.
WebP and AVIF conversion reduces image file sizes by up to 80%, leading to significantly faster page load times. Faster loading directly improves Core Web Vitals metrics (LCP, FID, CLS), which are key ranking factors for Google. The plugin also includes native lazy loading support, above-the-fold detection, and preserves all image metadata (alt text, attributes) for optimal SEO performance and accessibility compliance.
AVIF (AV1 Image File Format) is a newer image format that provides up to 50% better compression than WebP while maintaining superior quality. The plugin supports converting images to WebP only, AVIF only, or both formats simultaneously. When both formats are selected, the plugin automatically generates picture elements with AVIF as the primary source, WebP as fallback, and the original image as final fallback, ensuring maximum browser compatibility and optimal performance.
No, the plugin is extremely easy to use and requires no technical knowledge. Simply install and enable the plugin - it automatically converts images on-the-fly as pages load. Advanced features like batch conversion, directory management, and format selection are available through an intuitive admin interface with visual folder trees and real-time progress tracking.
WebP is supported by all modern browsers (Chrome, Firefox, Safari, Edge). AVIF support is growing rapidly and is available in Chrome, Firefox, and Opera. The plugin automatically provides intelligent fallback options: when both formats are enabled, it uses picture elements with AVIF → WebP → Original image fallback chain, ensuring perfect compatibility across all browsers and devices.
Yes, the plugin provides separate quality controls for both formats. WebP quality can be adjusted from 5-100%, while AVIF quality (5-100%) is automatically scaled to the 0-63 range that AVIF uses. You can also customize filename suffixes, preserve original timestamps, set minimum/maximum file size limits, and configure format-specific settings to achieve the perfect balance between file size reduction and image quality.
Yes, the plugin includes powerful batch conversion capabilities. You can select one, multiple, or all folders using the interactive folder tree interface, then choose to convert to WebP only, AVIF only, or both formats simultaneously. The batch process includes real-time progress tracking, detailed statistics, error reporting, and automatic directory creation. The system handles thousands of images efficiently with memory management and rate limiting.
Yes, the plugin automatically converts images on-the-fly as pages are loaded, ensuring immediate performance improvements without any delays. It uses intelligent caching (up to 90% reduction in processing overhead) to avoid re-converting images that haven't changed. The lightweight processing mode ensures minimal impact on page load times while providing comprehensive optimization for both inline images and CSS background images.
Lazy loading defers loading of images until they're about to enter the viewport, reducing initial page load time by up to 80%. This significantly improves Largest Contentful Paint (LCP) scores, a key Core Web Vitals metric that directly impacts search rankings. The plugin includes native browser lazy loading support with smart above-the-fold detection, ensuring critical images load immediately while off-screen images load only when needed.
Yes, the plugin is fully compatible with Joomla 4.x, 5.x, and 6.x. It uses modern Joomla APIs and namespaced classes, ensuring seamless integration without requiring backward compatibility plugins. The plugin automatically adapts to different Joomla versions and Media component configurations, working perfectly across all hosting environments (shared hosting, VPS, dedicated servers, cloud).
The plugin includes advanced memory management with configurable thresholds (60-90%). Operations automatically pause when memory limits are approached and resume when resources are available. The lightweight processing mode uses regex-based parsing to minimize memory consumption, while explicit resource cleanup prevents memory leaks. These features make it safe for shared hosting environments while maximizing performance on dedicated servers.
Yes, the plugin provides comprehensive exclusion controls. You can exclude specific image formats (JPG, PNG, GIF), individual images by filename, entire menu items, components, or URL patterns. Wildcard pattern support allows flexible exclusion rules. This is particularly useful for excluding admin areas, e-commerce checkout processes, or specialized components that may have compatibility requirements.
The plugin offers flexible directory management: store converted images in custom directories (webp_thumbs, thumbnails, etc.), maintain original directory structure, or use a flat structure where all WebP/AVIF files are stored in a single directory. You can use hashed MD5-based filenames to prevent conflicts, preserve original timestamps, and automatically clean up orphaned files when originals are deleted.
Yes, the plugin automatically preserves all image attributes including alt text, class names, IDs, styles, and loading attributes during conversion. This ensures accessibility compliance (WCAG guidelines), maintains SEO value of image metadata, and preserves any custom styling or JavaScript dependencies. The picture elements generated also maintain all original attributes for complete compatibility.
The plugin includes enterprise-grade security: all AJAX requests require valid CSRF tokens, comprehensive input validation prevents directory traversal attacks, rate limiting protects against abuse (5 batch ops, 50 single conversions, 10 delete ops per hour), and super administrators can bypass limits when needed. All file paths are sanitized and validated before processing.
The plugin includes a comprehensive debug mode that displays detailed statistics: original and converted file paths, file sizes, compression percentages, space saved per image, total savings, format-specific metrics (WebP/AVIF), memory usage, processing times, and cache performance. The advanced logging system tracks all operations with context information (user ID, IP address, timestamps) for troubleshooting and optimization.
AVIF support requires PHP 8.1+ with GD library that includes the imageavif() function, or ImageMagick extension with AVIF support. The plugin automatically detects AVIF capability and falls back to WebP if AVIF is not available. For WebP-only conversion, PHP 7.4+ with GD library is sufficient. The plugin gracefully handles missing capabilities and provides clear error messages.
Yes, the plugin is designed for enterprise-scale deployments. Features include: flat directory structure for large archives, hashed filenames to prevent conflicts, batch processing with progress tracking, memory management to prevent server overload, intelligent caching (90% reduction in repeat operations), lazy loading interface that handles thousands of folders, and rate limiting to prevent abuse. It's perfect for news sites, e-commerce platforms, and extensive image libraries.
The plugin uses a JSON-based caching system that stores conversion results and statistics, reducing processing overhead by up to 90% for repeat operations. Cache lifetime is configurable (1-168 hours) to suit different site types. The system automatically checks if original images have been modified (via file timestamps) and only re-converts when necessary. Automatic cache cleanup removes expired entries, and cache hit rates are monitored in debug mode.
Yes, the plugin is fully compatible with CDN and caching systems. It generates consistent, predictable URLs for converted images, preserves original timestamps for cache validation, and works seamlessly with Joomla's Media component configuration. The automatic URL generation ensures perfect integration with CDN services, and the plugin's caching system complements external caching layers for optimal performance.
