FAQ
-
Will this break my existing images?
-
No. The plugin creates additional WebP/AVIF files alongside your originals. Originals are never deleted (unless you disable “Keep Originals”).
-
What if WebP is larger than the original?
-
With Smart Compare enabled (default), the plugin automatically discards the converted file and keeps the original.
-
Does it work with CDNs?
-
Yes. The plugin detects WebP/AVIF files from the filesystem rather than relying on URL matching. An optional CDN URL setting is available for setups where image URLs use a different domain.
