I-PR AVIF Converter – Automatic Image Optimization vs NaveenCodes Image Optimizer

I-PR AVIF Converter automatically converts your existing and new images to AVIF format — the most efficient image format available today — without any cloud service, subscription, or API key. After 1 month of production testing across 6 live sites (5,089 images, 2.2 GB saved), this plugin achieves 40–70% file size reduction with zero visible quality loss and 0% conversion failure rate on both Aruba and Serverplan shared hosting. Real Production Results dermopigmentazioneroma.it — 904 images, 721 MB saved (-68%), Mobile PageSpeed 80/100 mangiaroma.com — 1,213 images, 804 MB saved (-70%), Desktop PageSpeed 97/100 artmerlino.it — 371 images, 167 MB saved (-64%) apicolturalapegaia.it — 1,069 images, 135 MB saved (-69%) fnahospitalityroma.it — 432 images, 83 MB saved (-43%) Total: 4,989 images converted. 0 failures. 2.2 GB saved. Why AVIF? AVIF is the next-generation image format supported by all modern browsers (Chrome, Firefox, Safari 16+, Edge). Compared to JPEG, it delivers 40–70% smaller files at equivalent visual quality. Compared to WebP, it delivers 20–30% better compression. Google PageSpeed Insights and Core Web Vitals (LCP) reward AVIF-optimized sites directly. How It Works When you upload an image, I-PR AVIF Converter queues it for background conversion via WP-Cron. No page load is blocked. Once converted, images are served automatically via the HTML element with a fallback to the original for older browsers: Your original files are never modified unless you explicitly enable “Delete Originals.” Key Features Zero cloud dependency — All conversion happens on your server using PHP’s native Imagick or GD library. No API keys, no usage limits, no recurring costs. Works on shared hosting — Tested and production-proven on Aruba Basic and Serverplan Eco/Basic. The plugin auto-detects your server’s encoder (Imagick or GD) and falls back gracefully. Adaptive batch processing (AIMD) — The plugin learns your server’s speed using an Exponentially Weighted Moving Average and automatically adjusts how many images it processes per cron run. It never causes timeouts or OOM errors. Memory guard — Before processing each image, the plugin estimates the required RAM based on image dimensions and encoder type (3.5× for Imagick, 1.8× for GD). If RAM is insufficient, the image is deferred to the next batch. No PHP Fatal errors. Circuit Breaker for Imagick — If Imagick fails 3 consecutive times, the plugin automatically switches to GD and retries Imagick after 30 minutes. No manual intervention required. Quarantine system — Images that fail 3 conversion attempts are automatically quarantined and excluded from future runs. You can review and retry quarantined images from the admin panel. Skip Patterns — Exclude specific images or folders using wildcard patterns (e.g., logos/*.png, 2024/03/*-banner.jpg). Useful for images where conversion is not desired. Bulk Scanner — Convert your entire existing media library with a real-time progress bar. The scanner is paginated and runs via AJAX without blocking the admin interface. Telemetry Dashboard — Real-time dashboard showing conversion rate, average compression ratio, fail rate, performance score, and a rolling chart of the last 200 conversion events. CDN integration — Automatic Cloudflare cache purge after each batch conversion, so your CDN always serves the latest AVIF files. Elementor & lightbox support — Gallery lightboxes (Elementor, Fancybox, WP native) are rewritten to serve AVIF in the full-size view, not just thumbnails. Animated GIF preservation — Animated GIFs are automatically detected (binary frame-count parsing) and excluded from conversion. AVIF does not support animation; the plugin never converts a GIF to a broken static file. CMYK image handling — Images from professional photography workflows (JPEG with CMYK color space) are automatically converted to sRGB before encoding to prevent color inversion artifacts. Clean uninstall — Removing the plugin deletes all database tables, options, transients, and the WP-Cron job. Zero ghost data left behind. WooCommerce Compatibility Tested on two active WooCommerce stores. Product images, gallery thumbnails, and checkout images are all converted and served correctly. Encoder Compatibility The plugin requires at least one of: Imagick ≥ 7.0.25 with libheif compiled with AV1 support PHP ≥ 8.1 with GD + libavif (imageavif() function available) The Settings page shows which encoders are available on your server and their current status (including Circuit Breaker state). PHP & WordPress Compatibility Tested on PHP 7.4, 8.0, 8.1, 8.2, 8.3. Compatible with WordPress 5.8 through 6.7. PHP 8.2+ deprecation warnings have been resolved. External Services This plugin optionally communicates with the Cloudflare API (api.cloudflare.com) to purge CDN cache after batch image conversion. This feature is disabled by default and only activates if you explicitly enable “Cloudflare CDN Integration” in the plugin settings and provide your own Cloudflare Zone ID and API Token. No data is sent to Cloudflare unless this feature is manually configured. The only data transmitted are the public URLs of newly converted AVIF images, which Cloudflare needs to purge from its cache. Cloudflare service: https://www.cloudflare.com Cloudflare Terms of Service: https://www.cloudflare.com/terms/ Cloudflare Privacy Policy: https://www.cloudflare.com/privacypolicy/ All image conversion is performed locally on your server. No images or personal data are ever sent to external services.

The plugin is designed to remain fully free: No locked features No artificial monthly limits No ads No tracking No upsells Features include: Automatic optimization on upload Async or sync processing modes Background queue backed by a custom database table Bulk optimization with progress updates and resume support Full compression profile controls in wp-admin for quality, resize rules, metadata handling, formats, retries, and batch size Automatic site-specific API key provisioning after plugin install Optional WebP and AVIF sidecar generation Automatic WebP/AVIF front-end serving via markup, with graceful fallback to the original format Optional backup copies before replacement Dashboard analytics for images optimized, bytes saved, compression rate, failures, queue status, and service health Media Library badge and single-image optimization action Before and after reporting for recently optimized images Local-only logging for troubleshooting Optional and non-intrusive donation page How It Works New uploads can be optimized automatically. Existing Media Library images can be queued in bulk. Individual images can be optimized directly from the Media Library. The dashboard shows total savings, failures, progress, registration state, and health status. External Service Disclosure This plugin connects to an external image optimization service in order to compress images. Service URL: https://naveencodes.com When the plugin communicates with the service, it may send: The image binary being optimized Optimization options such as quality, resize width, metadata handling, and output formats The site URL during automatic site registration The service is used only for optimization and registration required by the plugin workflow. No analytics or advertising scripts are included. No unrelated remote calls are made. No user account is required.
