详情介绍:
Thumbnail Manager helps you take back disk space from oversized Media Libraries.
What it does
- Prune Files: Select the image sizes you want to KEEP. The plugin scans your
/uploads/folder and targets all non-selected registered sizes for removal. It shows a dry-run summary first, then lets you delete in batches with a live progress bar. - Orphan discovery: Finds on-disk files that match
-WxHpatterns (including.jpg.webp,.bak.jpg, retina@2x, and duplicate-1suffixes) even if those sizes are no longer registered. Aggressively deletes any-WxHfiles that don’t exactly match the sizes you chose to keep (use with care). - Subfolder scope: Limit scans to a specific year/month inside
uploads/for faster, safer runs on large libraries. - Thumbnail Sizes: Choose which sizes should be generated for future uploads. Disabled sizes won’t be created at upload time (and are hidden from size pickers). What it doesn’t do
- It does not regenerate thumbnails. Use a regeneration plugin if you need to rebuild sizes after changing settings.
- It never deletes original full-size images. Who is it for? Site owners, editors, and developers who’ve accumulated many custom image sizes (themes, page builders, sliders) and want to reduce storage bloat safely.
安装:
- Upload the plugin folder to
/wp-content/plugins/or install via the Plugins screen. - Activate the plugin.
- Go to Tools → Prune Thumbnails.

常见问题:
Will this delete my original images?
No. It only targets derivative thumbnails that match registered sizes you did not keep or -WxH patterns from discovery. Originals are not deleted.
Do I need to back up first?
Yes, always back up your site and uploads before deleting files.
What’s “Orphan discovery”?
- Orphan discovery: scans and reports all
-WxHfiles found on disk (even if unregistered).
Does it unregister sizes?
Core sizes aren’t unregistered. For future uploads, the plugin prevents generation using filters. Custom sizes may be unregistered late during init (optional), but it’s not required to stop generation.
Multisite support?
Yes, run it per site from Tools → Prune Thumbnails.
Can it regenerate thumbnails?
No. This plugin focuses on pruning and preventing generation of unwanted sizes.
