A popular WordPress form plugin is installed on over 1 million WordPress websites. The favored culprit is Contact Form 7. It adds 37k page weight to all pages on your website. Even when the plugin is only used on one page – such as your contact page – the plugin “globally” slows down all pages. This “global” activation is even more problematic for heavier plugins like Google Maps or social media controls. We call global plugin activation “site drag.”
Other form plugins are lighter and faster. But substitution isn’t the solution or our main concern. What if we absolutely needed to use Contact Form 7 plugin because there is a special addon plugin that gives us more extended utility (And, there are addons!) How can you prevent global loading?
We fix it with a plugin that restricts a “heavy” plugin to just the pages where it’s needed.
Active installs: 100+
Zip file size: 15k
Active installs: 10,000+, Zip archive 295k
both let you deactivate or activate plugins on a page-by-page basis.
Update: We’ve located two others we haven’t tested yet – but they have potential. We’re surprised these have more downloads than Plugin Logic. Both are a heavier download. Once again, we see how product naming affects findability in the plugin directory.
Plugin Load Filter
Active installs: 4,000+, Zip archive 110k
WP Asset CleanUp (Page Speed Optimizer)
Active installs: 10,000+, Zip archive 1.4M
With these plugins, you can selectively disable plugins by any post type or WordPress-managed URL. But if you’ve read our recommendations about plugins and themes, you know we usually choose the lightest plugin when possible. Smaller file size usually equates with efficiency, which means it will probably load and work faster.
You don’t need to buy the $29 Gonzales plugin. Use one of these four alternatives instead.
Of the four plugins, Plugin Logic (only 100+ active installs) is the simpler and easier to use. It hasn’t been downloaded much yet compared to Plugin Organizer (10,000+ installs). Using the Plugin Organizer is more complicated because it let’s you change the plugin load order. Changing the load order can help prevent plugin conflicts, which is a nice bonus feature if you need it – but we don’t, so we’ll stick with Plugin Logic.

While our main focus is page-speed improvements, here’s another example of how plugin deselection can help:
We’re using the WP Image Borders plugin (266k compressed download) on a client’s website. It makes it easy to add image borders to pictures on pages or posts – but activation is global. The plugin adds borders to images on all pages.
But we don’t want borders around every image – as in the case of these circular buttons show here – the border ruins the look. So we deselect the border plugin for just that page. Problem solved.
