DZIEWA Media Converter creates sidecar .avif<\/code> and .webp<\/code> files next to your originals (no replacement of JPG\/PNG in the Media Library). On the front end it can rewrite <img><\/code> tags to <picture><\/code> so browsers pick AVIF\/WebP when available. The plugin is entirely free to use<\/strong> \u2014 no license fees, no pro version, and no paid add-ons.<\/p>\n\n

How it works<\/h4>\n\n

The plugin generates additional AVIF and\/or WebP files beside every JPEG\/PNG you upload. Originals are never touched or replaced \u2014 they remain in the Media Library and on disk as a safe fallback. The optional content filter detects <img><\/code> tags in your post content and wraps them in <picture><\/code> so modern browsers download the smaller AVIF\/WebP version, while older browsers transparently fall back to JPG\/PNG.<\/p>\n\n

Conversion<\/h4>\n\n
    \n
  • AVIF + WebP, AVIF-only or WebP-only<\/strong> output modes. AVIF requires PHP GD built with AVIF support; the plugin auto-detects this on activation and gracefully falls back to WebP-only when AVIF is unavailable.<\/li>\n
  • Configurable quality<\/strong> per format (independent AVIF and WebP quality sliders in settings).<\/li>\n
  • Automatic conversion on upload<\/strong> \u2014 new attachments are converted in the background via WP-Cron or Action Scheduler (when available), so the upload screen never blocks.<\/li>\n
  • Intermediate sizes (thumbnails)<\/strong> are optionally converted too, so every srcset variant has its own AVIF\/WebP sidecar.<\/li>\n<\/ul>\n\n

    Existing media<\/h4>\n\n
      \n
    • Background queue<\/strong> processes already-uploaded images in configurable batches (default 20 files per run, range 5\u2013200). You can scope the queue to a single uploads subfolder and\/or a date range to avoid scanning the whole library at once.<\/li>\n
    • Bulk action in the Media Library<\/strong> \u2014 select images and run Convert to AVIF\/WebP<\/strong> from the bulk menu.<\/li>\n
    • Per-attachment button<\/strong> \u2014 Media Library list, attachment edit screen and media modal each show a Convert to AVIF\/WebP<\/strong> button next to live savings stats (before\/after size, percentage saved per format).<\/li>\n<\/ul>\n\n

      Front end (content rewriting)<\/h4>\n\n
        \n
      • Optional <picture><\/code> rewrite in the_content<\/code> and post thumbnails \u2014 browsers automatically pick the lightest format they support.<\/li>\n
      • Lookup of attachment IDs from URLs is cached in the WordPress object cache (Redis\/Memcached when available) and memoised per request, so heavy pages with many images stay fast.<\/li>\n<\/ul>\n\n

        Tools & admin UI<\/h4>\n\n
          \n
        • Cleanup tool<\/strong> \u2014 remove old generated .avif<\/code> \/ .webp<\/code> sidecars by age (30\/60\/90\/120 days) and folder scope, with a per-folder picker.<\/li>\n
        • Admin bar download<\/strong> \u2014 optional link on singular posts\/pages to download the original JPG\/PNG of the featured image (useful for social platforms that don't accept AVIF\/WebP).<\/li>\n
        • Event log<\/strong> \u2014 last 100 events (errors, conversions, queue runs) visible on the settings page.<\/li>\n
        • Three-option uninstall dialog<\/strong> \u2014 when removing the plugin you choose between Cancel<\/em>, Remove (keep generated files)<\/em> or Remove and delete files<\/em>.<\/li>\n<\/ul>\n\n

          Privacy & dependencies<\/h4>\n\n
            \n
          • No external services, no remote calls, no tracking. Everything runs on your own server.<\/li>\n
          • Requires PHP 8.3+ and PHP GD with WebP support (imagewebp<\/code>). AVIF is optional.<\/li>\n
          • Fully translated to Polish; English source strings ready for further translations via GlotPress.<\/li>\n<\/ul>\n\n\n
              \n
            1. Upload the plugin folder to \/wp-content\/plugins\/<\/code> or install through the Plugins screen.<\/li>\n
            2. Activate the plugin. PHP must support WebP in GD (imagewebp<\/code>); AVIF is optional and auto-detected.<\/li>\n
            3. Configure settings under Settings \u2192 DZIEWA Media Converter<\/strong> in the admin menu, or use the Settings<\/strong> link in the Plugins screen.<\/li>\n<\/ol>\n\n\n
              \n

              Does this replace my JPG\/PNG files?<\/h3><\/dt>\n

              No. Original files stay in place; AVIF\/WebP are additional files beside them.<\/p><\/dd>\n

              What if my host has no AVIF in GD?<\/h3><\/dt>\n

              The plugin falls back to WebP-only modes and explains this on the settings page.<\/p><\/dd>\n\n<\/dl>\n\n\n

              1.5.23<\/h4>\n\n
                \n
              • New:<\/strong> Uninstall behavior<\/em> option in settings \u2014 opt-in checkbox to delete all generated .avif<\/code> \/ .webp<\/code> files when removing the plugin. Default is to keep the files (safe for reinstall).<\/li>\n<\/ul>\n\n

                1.5.22<\/h4>\n\n
                  \n
                • Frontend admin bar (optional):<\/strong> new setting to show a Download original featured image<\/strong> link on singular posts\/pages (when a featured image exists). Serves the original JPG\/PNG from disk with a forced download, useful for social platforms that expect a non\u2013AVIF\/WebP master file. Requires a user who can edit the post; uses a nonce on the download URL.<\/li>\n<\/ul>","raw_excerpt":"Converts JPEG\/PNG to AVIF and WebP; rewrites content to <picture> with JPG\/PNG fallback.
