详情介绍:
- Modern formats: new uploads are saved as AVIF or WebP (when your server supports them), JPEG otherwise.
- Compression levels: Best, Balanced, Smallest, or your own number, tuned per format.
- Largest size: oversized photos are scaled down to what your site actually shows.
- Your whole library: the Library screen finds heavy, oversized and badly compressed images and optimizes them in the background, one at a time.
- Dashboard widget: what can still be optimized and how much it saves, with a one-click Optimize button.
- TIFF to web: print TIFFs become images browsers can show (when your server's image library reads TIFF).
- Replace originals (optional): free disk space by keeping only the optimized file, and only when it is smaller.
- Safe on small servers: photos too big for your server's memory are stored as uploaded instead of crashing the upload, and ImageMagick gets a memory budget inside containers.
- which image library WordPress uses (ImageMagick or GD) and which formats it can read and write;
- how large a photo it can process comfortably with its memory;
- whether background tasks (WP-Cron) run, the time limit per request, the upload limit and free disk space;
- a speed test that times WebP and AVIF on this server and estimates seconds per photo;
- a feature-by-feature comparison of this server with TheDock Cloud, and a report to paste into support requests.
- no image work on your server: uploads return instantly, whatever their size;
- AVIF and WebP on every site, encoded fast, for photos up to 100 MP;
- videos: a web MP4 that plays everywhere, a smaller AV1 or VP9 version and a poster image;
- Compare before choosing: up to 8 formats and quality levels on your own image or video, side by side and zoomable, each with a score for how close it looks to the original;
- bulk optimization in parallel.
安装:
- Install and activate the plugin. The setup opens.
- Choose where images are processed: this server (free) or TheDock Cloud (click Connect to TheDock, or paste your site's key from thedock.app → Media).
- Pick a format and quality level, then let it optimize your existing images, or review them first under TheDock → Media → Library.

常见问题:
Do I need a TheDock account?
No. Without one, everything happens on your own server for free. TheDock Cloud is optional.
Is it really free and unlimited?
Yes. On your own server there is no quota, no credits and no limit on the number of images. The only limits are your server's: TheDock → Media → Server shows how large a photo it handles comfortably.
What does TheDock Cloud cost?
Your TheDock account can try it free on 5 files, once, across all your sites. After that it is $2 per site per month, or $20 per site per year, which includes 5,000 files and 30 minutes of video per site each month. If the trial is used or a site isn't subscribed, the plugin keeps working: new images are optimized on your own server, and an admin notice links to the subscription. Usage, speed and the service's online time are on thedock.app → Media → Usage.
Why doesn't my server create AVIF?
AVIF needs PHP 8.1 or newer with AVIF support in GD, or ImageMagick built with AVIF. TheDock → Media → Server shows what your server supports. Until then, images are saved as WebP (or kept in their format), and TheDock Cloud can create AVIF for any site.
What happens to images uploaded before I installed the plugin?
Nothing until you choose: TheDock → Media → Library (or the last setup step) optimizes them in the background. On the command line: wp thedock-media regenerate --missing.
Will big uploads crash my server?
The plugin checks how large a photo your server can handle. Bigger photos are stored as uploaded and marked "Too large for this server", instead of exhausting memory. TheDock Cloud processes them without using your server.
Is there a command line?
Yes: wp thedock-media regenerate, audit, status and server (the server check, --speed adds the speed test).
Can I turn it off?
Untick "Optimize new uploads" in the settings, or deactivate the plugin. Generated files are ordinary WordPress files and stay.
更新日志:
- Works with the TheDock theme's black-and-white images: after an image is converted to WebP or AVIF, its black-and-white versions are made again in the new format and the old ones are removed. Images converted before this update are caught up once in the background.
- Optimizes images for free on your own server: resizes oversized photos, compresses them and converts them to WebP or AVIF with WordPress's own image tools, on upload and for your existing library.
- Setup in about two minutes: a live check of this server, side by side with TheDock Cloud, then a quality level chosen on samples of your own images.
- Library: finds heavy, oversized and badly compressed images, shows what optimizing each would save, and optimizes one, a selection or everything in the background.
- Overview and a Dashboard widget, both live while images are optimized: how much lighter your images can get and what was saved so far.
- Server screen and a Site Health check: what this server can and can't do, with a speed test and a report for support.
- Safe by default: originals are kept unless you choose to replace them, and an original is never replaced by a bigger, empty or broken file.
- Optional TheDock Cloud: connect with one click to move the work off your server, add video (web MP4, AV1 or VP9 and a poster) and Compare formats side by side before choosing. Try it free on 5 files and see what they became before choosing.
- One TheDock menu: the pages (Overview, Library, Compare, Server, Settings) sit under TheDock → Media, shared with other TheDock plugins.
