I-PR AVIF Converter – Automatic Image Optimization vs ProRank SEO

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.

Production bundles are generated into build/. Build steps: 1. npm install 2. npm run build External Services ProRank SEO connects to external services only for features that need them. Requests are made only after an administrator enables or runs the relevant feature, except for normal WordPress-scheduled checks such as the notification feed. The Free plugin package is updated only through WordPress.org; it does not contain ProRank’s private Premium updater. ProRank API — Admin notifications, changelog checks, optional feedback submissions, optional cache diagnostics, security alerts, extension metadata, and cloud image optimization where explicitly enabled/available. Sends site URL, plugin version, license key or tier where configured, feedback fields when you submit feedback, image files when cloud optimization is enabled, and diagnostic/error context for security or cache checks. The ProRank API is not used to deliver Free plugin package updates. Terms | Privacy Google PageSpeed Insights API — Core Web Vitals and performance audits. Sends the analysed URL and optional API key. Terms | Privacy YouTube Data API — Optional video-sitemap metadata enrichment when you provide a YouTube API key. Sends the detected YouTube video IDs and your configured API key. Terms | Privacy Hosted video metadata — Video sitemaps can request public titles, descriptions, thumbnails, dates, and durations for detected Vimeo, Dailymotion, VideoPress, and TED videos. Sends only the detected public video URL; VideoPress also receives the requesting site host required by its oEmbed API. Requests use fixed provider endpoints, are cached, and run only while generating a sitemap containing those videos. Vimeo | Dailymotion | WordPress.com | TED Schema.org Validator — Schema validation. Sends the validated page URL. Terms IndexNow — Instant indexing notifications. Sends host, API key, and URLs. Protocol Sitemap Pings — Notifies Google and Bing of sitemap updates. Sends the sitemap URL. Google Fonts — Downloads fonts locally when local hosting is enabled. Sends the font request URL. Website Carbon API and Green Web Foundation API — Sustainability reports send page byte counts and the site’s hostname to estimate emissions and check green-hosting status. Requests run only when an administrator runs sustainability analysis and successful results are cached. Website Carbon Terms | Website Carbon Privacy | Green Web Foundation Privacy CDN provider APIs (optional) — After an administrator selects a provider and supplies credentials, ProRank can test the connection, detect a Cloudflare zone, manage supported Cloudflare settings, and purge cached URLs. Requests go directly from the WordPress server to the selected provider. They can include the configured zone, service, pull-zone or distribution ID; authentication token, key ID or signed authorization header; the site hostname; and URLs or paths selected for invalidation. An AWS secret key is used locally to sign CloudFront requests and is not transmitted verbatim. Requests occur only on an explicit connection/settings action or a cache purge while that provider is configured. ProRank does not upload or proxy site assets through prorank.io as part of these controls. Cloudflare Terms | Cloudflare Privacy | bunny.net Terms | bunny.net Privacy | Fastly Terms | Fastly Privacy | AWS Service Terms | AWS Privacy | KeyCDN Terms | KeyCDN Privacy Administrator-configured webhooks (optional) — A CDN purge webhook receives a connection-test request or a JSON purge action with the affected public URLs. Audit-alert webhooks receive the event and report fields selected by the administrator. Requests are sent only after an administrator saves and uses that endpoint. The endpoint is controlled by the site owner, so its terms and privacy policy are those of the chosen webhook operator. User-configured CDN URL rewriting (not a ProRank proxy) — When an administrator enters a CDN base URL, ProRank rewrites eligible URLs for static files already hosted by the site. This feature makes no server-side upload or proxy request. A visitor’s browser requests the rewritten asset directly from the administrator’s chosen CDN, which receives the visitor IP address, standard request headers, and requested asset path under that provider’s terms. Nothing is routed through prorank.io by this rewrite feature. Trustindex loader localization (optional) — When the matching performance governance feature is enabled and the site already includes a Trustindex widget loader, the WordPress server can retrieve that public loader URL, adapt it for deferred local delivery, and cache the resulting file under WordPress uploads. Trustindex receives the requested loader URL, the server IP address, and standard HTTP request data; ProRank does not send visitor form data or WordPress database content. Trustindex Terms | Trustindex Privacy Static hostnames for Google Maps, CAPTCHA providers, payment gateways, booking tools, WordPress emoji resources, and public CDNs also appear in ProRank’s compatibility, privacy, and sustainability catalogues. Those entries identify or protect resources already added by WordPress, the theme, or another plugin; the lists themselves do not load those services or send them data.
