Title: OptiFusion – Image Converter & Optimizer Author: deshraahi Published: July 24, 2026 Last modified: August 29, 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.7.2.zip) * [Details](https://test.wordpress.org/plugins/optifusion-image-converter-optimizer/#description) * [Reviews](https://test.wordpress.org/plugins/optifusion-image-converter-optimizer/#reviews) * [Installation](https://test.wordpress.org/plugins/optifusion-image-converter-optimizer/#installation) * [Development](https://test.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 * 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 * Force Re-optimize All Images — re-process your entire library after changing format, quality, or other settings, not just new uploads * 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) or the GD library (fallback, available on almost every server). ### 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. ### I changed the quality/format settings, but Bulk Optimize isn’t re-processing my images. Why? By default, Bulk Optimize only processes images that have never been optimized before, so it skips images that were already processed under your old settings. Go to OptiFusion Bulk Optimize and use the “Force Re-optimize All Images” button to re-process every image in your Media Library with your current settings. ### I have images left over in AVIF format from an older version of OptiFusion. What do I do? AVIF output was removed starting in version 7.2 — OptiFusion now converts everything to WebP only. If you still have images in AVIF format from before, go to OptiFusion Settings, where you’ll see a “Migrate AVIF to WebP” button that converts them for you in one click. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “OptiFusion – Image Converter & Optimizer” is open source software.

Added a one- click “Migrate AVIF to WebP” tool (Settings page) for images already converted to AVIF by an earlier version. * Fixed Bulk Optimize only ever running once: images that were already optimized were permanently skipped on later runs, even after changing format/quality/other settings. Added a “Force Re-optimize All Images” button on the Bulk Optimize page to clear optimization data and re-process the entire Media Library with current settings. #### 1.3.0 * Added AI Tools page: local duplicate/similar image finder (free, unlimited), local low-quality/blur detector (free, unlimited), and AI-powered alt-text + tag generator using the Google Gemini free tier. #### 1.2.0 * Added Unused Images finder — scan the Media Library for images not used anywhere on the site, select them, and bulk delete. * Converted all admin UI text to plain English. #### 1.1.0 * Added WebP fallback mode using tags for old browser support. * Added lazy loading (native + advanced JS/IntersectionObserver mode). * Added CDN integration with URL rewriting. #### 1.0.0 * Initial release. ## Meta * Version **7.2** * Last updated **1 week ago** * Active installations **Fewer than 10** * WordPress version ** 5.6 or higher ** * Tested up to **7.0.4** * PHP version ** 7.4 or higher ** * Language * [English (US)](https://wordpress.org/plugins/optifusion-image-converter-optimizer/) * Tags * [compress images](https://test.wordpress.org/plugins/tags/compress-images/)[image optimization](https://test.wordpress.org/plugins/tags/image-optimization/) [lazy load](https://test.wordpress.org/plugins/tags/lazy-load/)[media library](https://test.wordpress.org/plugins/tags/media-library/) [webp](https://test.wordpress.org/plugins/tags/webp/) * [Advanced View](https://test.wordpress.org/plugins/optifusion-image-converter-optimizer/advanced/) ## Ratings No reviews have been submitted yet.
