## 描述

A simple and lightweight plugin that can automatically convert Media images to the
WebP or AVIF image format as they are uploaded. Includes the ability to add watermarks
to uploaded images. Support for optionally retaining backups of the original image.

 * No cost, no subscriptions
 * No reliance on transmitting your images to a third party server
 * Support for multisite networks
 * No third-party PHP libraries are used
 * JavaScript is native (does not use jQuery)

**Modern image formats**

AVIF images are [~50% smaller than JPEG images](https://web.dev/articles/compress-images-avif),
and WebP images are [~30% smaller than JPEG images](https://developers.google.com/speed/webp/docs/webp_study)
with the same image quality.

## 常见问题

### Does this work with multisite networks?

Yes. This can be deployed on a per-side basis or network-wide for all sites.

### Does this convert images I’ve uploaded in the past?

It does not convert images uploaded before installing this plugin. Changing image
extensions and URLs after the fact can lead to issues where previously referenced
images no longer work.

If you use Cloudflare (even the Free plan), you can use Image Transformations to
automatically convert legacy images to modern formats with the free [App for Cloudflare®](https://wordpress.org/plugins/app-for-cf/)
plugin.

### I have an idea for this plugin, can I make a suggestion?

Yes, please do! You can find the suggestion area [over here](https://wordpress.org/support/plugin/image-shift/).

Finally, an extension capable of converting to AVIF or WebP and adding a watermark
for free and without using a CDN. Plus, it doesn’t display ads all over the admin
interface to push for the CDN version. My only regret is that you can’t choose to
keep a backup of the original image or remove the watermark. Maybe in a future update?
