原文外掛簡介
WordPress creates many image sizes when you upload a photo. This plugin tunes each size to a suitable quality level so pages load faster, while keeping the pictures looking good.
It works with sensible defaults as soon as you install and activate it. You do not need a long setup to get started.
Runs entirely on your server
Processing stays on your own hosting. There are no cloud conversion fees, usage credits, or third-party watermarks.
When images are rebuilt, the plugin always starts from your original upload. Even if you change settings and regenerate again and again, quality does not degrade across generations (generational degradation).
That helps both cost and long-term image quality.
Automatic WebP and AVIF
WebP and AVIF are next-generation formats that keep high image quality at smaller file sizes.
On compatible servers, the plugin builds those versions and serves them to browsers that support them — without rewriting image URLs in your content.
Adjust settings yourself (optional)
You can leave the defaults as they are, or adjust compression yourself for each size and format (JPEG, PNG, WebP, and AVIF).
This is especially useful on WooCommerce and other product sites, where product thumbnails can be lighter for fast catalog pages while larger product photos stay sharper for detail views.
There is also an optional quality test screen if you want to compare settings with your own eyes.
Automatic optimization (optional, beta)
After upload, the plugin can keep working in the background to find a smaller file that still looks close to the original.
A second check helps avoid images that look too blocky or soft.
Progress and size savings are recorded per image.
Protecting your privacy
Uploaded photos often contain EXIF metadata — for example GPS location, camera model, or the time the shot was taken.
By default, the plugin removes EXIF data when images are processed, which helps protect visitors’ and photographers’ privacy.
You can turn this off in the settings if you need to keep EXIF.
