Disable Embeds

Works exactly as advertised. Thank you.

That does it without any extra clutter added to the admin. Thanks :)

Perfect

An easy way to drop some weight if you don’t need the functionality that the plugin disables. For me this has been a “set and forget” plugin. 

Does what it says, has been reliable

thanks

Finally, a no-fuss plugin that does exactly what it promises! Disable Embeds by Pascal Birchler is perfect if you're tired of WordPress's automatic embed features slowing down your site. Just activate and boom - no more unwanted embeds cluttering your content or others embedding your posts without permission. Love how it removes all the JavaScript bloat too. The best part? It's reversible - just deactivate when you need embeds back. Clean, lightweight, and effective!

Simple Solution to WordPress Embed Bloat
