Frequently Asked Questions

Common questions about Thumbnail Manager

Not during cleanup. Thumbnail Manager moves matching thumbnail files into plugin Trash first so they can be restored later. To free disk space permanently, use Delete Permanently for one trash batch or Empty Trash for all batches in the Trash and Restore table.

Preview performs a dry run and shows how many files match your current selection, which sizes are involved, how much space can be recovered, and how many orphan thumbnails were found.

Orphan thumbnails are files such as image-300x300.jpg that still exist on disk but are no longer tracked in WordPress attachment metadata.

The plugin scans image attachments and checks for usage in featured images, parent attachments, post content, and stored builder/meta content. The results are best treated as “probably unused” so you can review them manually.

Yes. The size-disable settings prevent selected image sizes from being generated for future uploads only. Existing thumbnails are not removed unless you explicitly preview and move them to Trash.

Yes. Use the Regenerate Missing Sizes section to rebuild missing image sizes in batches, switch to a full rebuild mode when needed, or use Media Library bulk actions for selected images.

Yes. The advanced filters can narrow analysis, cleanup, and regeneration jobs by image format, attachment usage status, and whether the thumbnail files are metadata-tracked or orphaned.

Yes. The WebP generation tool can create .webp copies for JPEG and PNG originals plus their registered thumbnail sizes when your WordPress image editor supports WebP output.

Yes. You can connect a TinyPNG API key and run bulk optimization against original uploads, generated thumbnails, or both while keeping the files in place.

Yes. Analysis, cleanup, and regeneration are processed in batches with visible progress to reduce timeout problems on larger WordPress sites.
