Frequently Asked Questions

Common questions about Stintlief WebP Converter

Currently, the plugin only converts images as they are uploaded. Bulk conversion of existing media library images will be added in a future version.

By default, the plugin keeps the original file if the WebP version is larger. You can force WebP conversion regardless of size using the "Force WebP" option (not recommended).

Yes! If you enabled "Keep a backup" (enabled by default), you can restore the original from the attachment edit screen using the "Restore original file" button.

WordPress automatically uses the converted WebP files. If you restore an original, WordPress will regenerate thumbnails and update references.

Modern browsers (Chrome, Firefox, Edge, Safari 14+) support WebP. Older browsers fall back to WordPress's standard image handling. The plugin doesn't modify HTML markup.

Yes, this plugin focuses only on WebP conversion and works alongside caching and CDN plugins. Apply this plugin's conversion first, then use other optimization tools.

Animated GIFs are automatically detected and skipped to preserve their animation. They will not be converted to static WebP images.

Backups are stored in the same directory as the original file with .stwp-backup added to the filename. For example: image.stwp-backup.jpg

Settings are removed, but converted images and backups remain on your server. This prevents accidental data loss. You can manually remove backup files if desired.
