Frequently Asked Questions
Common questions about Erdo Image Optimizer – Image SEO, AI Alt Text, Media Cleanup, WebP & AVIF
No. WebP and AVIF copies are saved next to the originals, and "Remove copies" simply deletes them. Three features do write files, and only when you use them: renaming moves files to the new name (and can be undone), resizing in the detail panel creates a smaller version and keeps the original for undo, and the optional "Remove camera data (EXIF)" setting rewrites each new upload once.
Quarantine replaces deletion. The image's files (all sizes and copies) are moved to a folder with an unguessable name inside your uploads directory and the image is hidden from the media library. Nothing is lost: open the Cleanup tab and click Restore on one image, or "Restore all". Images are deleted permanently only when you choose to, or after a number of days if you turn on automatic emptying (off by default).
It keeps an index of every place an image is referenced: post and page content (by ID and by URL, including resized, -scaled and WebP/AVIF URLs), featured images, galleries, custom fields and page builder data, theme settings, widgets, site logo and icon, term images and WooCommerce galleries. Drafts and trashed posts count as used. An image that is only attached to a post but not shown in it counts as unused. It cannot see images hard-coded in theme or plugin PHP files, images used only in CSS files, images stored in custom database tables, or images linked from other websites. That is why unused images go to quarantine first.
Yes. The default delivery method writes <picture> tags into the HTML, so every browser gets a URL it can use and caches do not mix formats up. The .htaccess method serves different files under the same URL; use it only if your CDN respects the Vary: Accept header. The setup detects Cloudflare and recommends <picture> tags.
LiteSpeed and OpenLiteSpeed read the same rules as Apache, but apply a changed .htaccess only after up to a minute, so check the result after that. nginx does not read .htaccess: copy the snippet from Settings > Delivery into your server { } block (not inside a location) and reload nginx. In both cases the old URLs of renamed images keep redirecting.
Anthropic (Claude), Google (Gemini) or OpenAI, connected under Settings > Connectors in WordPress 7.0 or newer. You pay your provider directly, with your own key. The plugin prefers small, inexpensive vision models; its own estimate is roughly $0.15 to $0.40 per 1,000 images, shown before every bulk run. Actual prices depend on your provider and model.
For each image: the image itself (at most 1024 px on the long side) plus short text context, namely the title of the page it appears on, up to 500 characters of text around it, the focus keyword, the current alt text and title, the content language, and the product name and categories for WooCommerce products. No user names, e-mail addresses or other personal data are sent. Requests happen only when you ask for a suggestion, or after an upload if you turn on "Suggest on upload". Nothing is written to your images until you accept a suggestion. See "External services" below for details.
wp erdo convert [--id=<id>] [--year=<year>] [--limit=<n>] [--dry-run] creates WebP/AVIF copies. wp erdo restore --id=<id> removes the copies of one image. wp erdo audit [--format=table|csv|json] [--limit=<n>] [--status=red|orange|green|gray] prints SEO scores and issues. wp erdo stats shows library and encoder statistics. wp erdo index [--status] builds the usage index or shows its status. wp erdo unused [--format=table|csv|json|ids] lists unused images. wp erdo quarantine list|add|restore|purge|add-unused [--id=<id>] [--yes] manages the quarantine. wp erdo rename [<id>...] [--all] [--name=<name>] [--pattern=<pattern>] [--keyword=<keyword>] [--dry-run] [--undo=<batch>] renames images safely. wp erdo migrate [--dry-run] [--batch=<n>] repairs images converted by version 2.x. wp erdo clean-cache clears the audit cache.
Your original images stay. Settings, the usage index, scores, rename history and the .htaccess rules are removed; old-URL redirects stop working at that point. Under Settings > Uninstall you choose whether the WebP/AVIF copies are deleted (default) or kept, and whether quarantined images are put back into the media library (default) or deleted permanently. Deactivating the plugin only removes the .htaccess rules and scheduled tasks.
Version 2.x replaced originals with WebP files and did not update the image links in your content, which could leave broken images. Version 3.0 never does this. After updating, if the plugin finds images converted by 2.x, a notice offers "Repair now" (or run wp erdo migrate). If a 2.x backup exists, the original is put back and a WebP copy is created next to it. If there is no backup, links to the old JPEG/PNG files are pointed to the existing WebP file, safely for serialized data. Until the repair runs, a fallback keeps such images visible on your pages. SVG uploads, the BunnyCDN integration, the lazy-loading filter and the network settings page were removed in 3.0. For SVG, use a dedicated plugin such as Safe SVG; for BunnyCDN, use a pull zone.
