Frequently Asked Questions

Common questions about SEV WebP Migrator for W3TC

No. Image conversion is handled entirely by W3 Total Cache ImageService. This plugin only replaces already-converted images' URLs, permanently, wherever they're referenced (see the next question) and in the attachment's own record.

Widget instances (e.g. a Custom HTML/Text widget) and theme mod settings (e.g. a Customizer background image or "Additional CSS") are updated, in addition to post_content. Content stored elsewhere, such as a page builder's own design data (e.g. Elementor), is not scanned; if an image is referenced only from such a source, delete original files with care.

A source file is only deleted once its .webp counterpart has been confirmed to exist on disk, after post content, widgets, theme mods, and the attachment record have already been updated. For a freshly-uploaded image, deletion is additionally deferred for a short grace period (15 minutes by default) to avoid interfering with an active editing session. Deletion is still permanent and disabled by default — enable it deliberately, and keep backups.

Yes. Each site processes its own W3 Total Cache ImageService conversions independently.
