原文外掛簡介
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, Privacy Policy.
The plugin’s duplicate-image finder and blur detector run entirely
locally on your own server and do not send any data anywhere.
