常见问题:

Which image formats are supported?

New uploads in JPG, JPEG, PNG, and AVIF format can be converted to WebP. Existing supported images can also be processed through Bulk Compress.

Does the plugin modify existing images automatically?

No. Existing images are only processed when you run the bulk compression or watermark rebuild tools.

Does this plugin support watermarking?

Yes. You can upload a watermark logo, choose the position, opacity, size, and margin, and optionally exclude specific images.

Can I clean unused images from my Media Library?

Yes. The plugin includes an unused media scanner and cleaner to help identify media items that are not referenced in content or common metadata. Back up your media library before deleting files. The scanner cannot detect every reference made by themes, page builders, or external sites. Deletion permanently removes the selected attachments and their files.

Who can run bulk compression?

Administrators with the manage_options capability can start, advance, or cancel bulk compression across the media library.

What does Image SEO Metadata do?

It can fill missing image ALT text and attachment descriptions when posts are saved. Basic mode uses the post title and meta description or excerpt. Advanced mode uses nearby headings and section text for content images.

Will Image SEO Metadata overwrite custom ALT text?

No. Future post saves fill empty fields by default. Backfill tools separate missing, generated Basic, generated Advanced, and custom image metadata so you can safely update only the intended group.

What format does the Featured Image Generator use?

The Featured Image Generator saves JPEG files to keep smooth gradient output predictable between 20 KB and 60 KB.
