Title: OptiFusion – Image Converter & Optimizer Author: deshraahi Published: July 24, 2026 Last modified: July 24, 2026 --- Search plugins ![](https://ps.w.org/optifusion-image-converter-optimizer/assets/icon-256x256.png? rev=3621871) # OptiFusion – Image Converter & Optimizer By [deshraahi](https://profiles.wordpress.org/deshraahi/) [Download](https://downloads.wordpress.org/plugin/optifusion-image-converter-optimizer.zip) * [Details](https://wordpress.org/plugins/optifusion-image-converter-optimizer/#description) * [Reviews](https://wordpress.org/plugins/optifusion-image-converter-optimizer/#reviews) * [Installation](https://wordpress.org/plugins/optifusion-image-converter-optimizer/#installation) * [Development](https://wordpress.org/plugins/optifusion-image-converter-optimizer/#developers) [Support](https://wordpress.org/support/plugin/optifusion-image-converter-optimizer/) ## Description OptiFusion optimizes your entire WordPress Media Library: * Bulk convert PNG/JPG images to WebP or AVIF * Smart lossy/near-lossless compression (adjustable quality) * Auto-optimize every image the moment it’s uploaded * Automatic backup of original images with one-click restore * Strip EXIF/metadata for extra savings * Optional max-width resize for oversized images * WebP fallback via tags — modern browsers get WebP, old browsers (e.g. IE11) automatically get the original image * Lazy loading — native `loading="lazy"` or an advanced IntersectionObserver-based JS loader with automatic fallback for very old browsers * CDN integration — serve all images (and their srcset/thumbnails) from your own CDN by simply entering its URL * Unused Images finder — scan your entire library for images not referenced anywhere on the site, select them, and bulk delete * Dashboard shows total images, space saved, and average savings * Works via WordPress’ native `wp_generate_attachment_metadata` hook, so it’s compatible with page builders, importers, and the REST API * No conflicting global functions/classes — everything is prefixed OptiFusion_/` optifusion_` Works with either the Imagick PHP extension (recommended, supports AVIF) or the GD library (fallback, WebP only on most setups). ### External services This plugin’s optional **AI Tools** feature (alt-text and tag generation for an image) connects to the **Google Gemini API** (generativelanguage.googleapis.com). * This is only used if you enter your own Google Gemini API key on the AI Tools settings page and explicitly click “Generate” on a specific image. No data is sent unless you take this action. * When used, the selected image’s file data is sent to Google’s servers so the Gemini model can analyze it and return a suggested alt text and tags. * This service is provided by Google LLC: [Terms of Service](https://ai.google.dev/gemini-api/terms), [Privacy Policy](https://policies.google.com/privacy). The plugin’s duplicate-image finder and blur detector run entirely locally on your own server and do not send any data anywhere. ## Screenshots [[ [[ [[ [[ [[ ## Installation 1. Upload the `optifusion` folder to `/wp-content/plugins/` 2. Activate the plugin through the ‘Plugins’ menu in WordPress 3. Go to OptiFusion Settings to configure format/quality 4. Go to OptiFusion Bulk Optimize to process your existing library ## FAQ ### Will this break existing image URLs on my site? When an image is converted to a new format, OptiFusion updates the WordPress attachment record and regenerates thumbnail sizes, so URLs used through WordPress functions stay correct. Hard-coded URLs in custom code that reference the old file extension would need updating. ### Can I undo the optimization? Yes — enable “Backup Original Images” in Settings (on by default) and use the Backup& Restore page to revert any image, or all images at once. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “OptiFusion – Image Converter & Optimizer” is open source software.
