Thumbnail Remover and Size Manager

Not during cleanup. Version 2 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.

Yes. You can create a zip backup for all uploads or for a selected year/month folder, and cleanup can also create a zip backup of the exact matching thumbnails before they are moved to plugin Trash.

Yes. Each cleanup run creates its own Trash batch, so you can restore a specific batch independently.

Use Empty Trash in the Trash and Restore table to remove every batch, or use Delete Permanently for a single batch. This deletes the stored trash files and any backup stored with those batches, and it cannot be undone.

No. Scheduled cleanup uses the same plugin Trash flow as manual cleanup, so matching thumbnails can still be restored later.

The reporting section shows recent analysis, preview, cleanup, restore, regeneration, backup, and scheduled cleanup activity along with summary totals for recovered storage and other media operations.

Yes. That is exactly what orphan thumbnail detection is for. These files are included in analysis and preview results so you can decide whether to move them to Trash.

No. The plugin marks items as probably unused based on several WordPress relationships and content checks, but you should still review those results manually before broader media cleanup decisions.
