How to Regenerate Thumbnails in WordPress?

Frequently Asked Questions

Why do WordPress images look wrong after changing a theme?

Themes define image sizes. When you switch themes, existing images don’t update automatically, so thumbnails must be regenerated to match the new sizes.

Does WordPress regenerate thumbnails by default?

No. WordPress creates image sizes only at upload time. Existing images stay unchanged unless you manually regenerate thumbnails.

Do I need another plugin just to regenerate thumbnails?

Normally, yes, but Nexter Extension includes thumbnail regeneration as part of a single modular plugin, reducing the need for extra tools.

Will regenerating thumbnails affect my original images?

No. Regeneration only recreates image sizes based on existing originals. The original uploaded image remains untouched.

Is this safe for large media libraries or client sites?

Yes. The process runs with progress tracking, making it suitable for large sites and agencies managing multiple WordPress installs.

Does this fix WooCommerce product image issues?

Yes. It regenerates WooCommerce-specific image sizes so product images display correctly across shop and product layouts.
