Can I serve `.webp` files without using the `` tag?

If you uncheck Serve WebP the files stay on disk but the plugin will not wrap your markup. You can then serve them yourself (e.g. via Nginx Accept negotiation or a CDN rule).

Frequently Asked Questions

Common questions about Petro SEO Images to WebP

No. Originals stay on disk. The plugin writes a sibling file with the .webp extension (e.g. photo.jpg and photo.jpg.webp).

On Media → Petro SEO Images to WebP, click Revert all. Every generated .webp file is removed and the tracking metadata is cleared.

The most common cause is a write-permission issue on the uploads folder. Fix the directory permissions (e.g. chown www-data:www-data on Linux) and click Retry skipped to reprocess only those.

Yes. The <source> element inside <picture> carries the full srcset and sizes, with each URL pointing to its .webp counterpart. URLs whose .webp is missing on disk are silently dropped from the WebP srcset so the browser falls back to the original <img>.

If you uncheck Serve WebP the files stay on disk but the plugin will not wrap your <img> markup. You can then serve them yourself (e.g. via Nginx Accept negotiation or a CDN rule).

The plugin retries with progressively lower quality (down to 40). If even at the lowest quality the WebP is still bigger than the source, it logs a diagnostic line and uses what it has — most browsers will still benefit from the format.
