How to Install a Plugin in WordPress (3 Methods + Safety Checklist)

Plugins are what make WordPress so flexible: contact forms, SEO tools, backups, security, online stores and thousands more features are one install away. This guide shows three ways to install a plugin, a quick safety checklist, and how to recover if a plugin breaks your site.
Method 1: From the WordPress plugin directory
- Go to Plugins > Add New Plugin.
- Search by name or feature, for example "contact form".
- Click Install Now on the plugin you want, then Activate.
- Look for the plugin's new menu item or settings link and configure it.
Method 2: Upload a zip file (premium or custom plugins)
Premium plugins and plugins from developers' own websites come as a .zip file.
- Download the zip. Do not unzip it.
- Go to Plugins > Add New Plugin > Upload Plugin.
- Choose the file, click Install Now, then Activate Plugin.
- Enter the licence key if it is a premium plugin, so it receives updates.
You can practise with the free SWS Site Fixer plugin in the download box below.
Method 3: Upload through File Manager or FTP
Use this when the upload is too large for your server limit or the dashboard is unavailable.
- Unzip the plugin on your computer.
- Upload the plugin folder to
wp-content/plugins/with your host's File Manager or an FTP client. - Go to Plugins in WordPress and click Activate.
If the dashboard upload fails with a size error, raise your limit with our upload size guide.
Safety checklist before installing
- Last updated: within the last few months is a good sign.
- Active installations and ratings: popular, well-rated plugins are generally safer.
- Compatibility: tested with your WordPress version.
- Support: are support questions answered?
- Source: WordPress.org or the official developer only. Never nulled copies.
- Need: can you achieve this without a plugin? Fewer plugins means fewer updates and conflicts.
If a plugin breaks your site
A blank screen or "There has been a critical error" right after activating a plugin means it conflicts with something. Rename its folder in wp-content/plugins through File Manager to deactivate it, then follow our critical error guide.
Keep plugins healthy
- Update regularly, and take a backup before major updates.
- Delete plugins you no longer use, not just deactivate them.
- Review your plugin list every few months as part of the security checklist.

Frequently asked questions
How many plugins should a WordPress site have?
There is no fixed number. What matters is quality: keep only well-maintained plugins you actually use. One heavy or badly coded plugin can cause more problems than twenty light ones.
Why can't I see Add New under Plugins?
Either your user role is not Administrator, or you are on a WordPress.com plan that does not allow plugins. Self-hosted WordPress.org sites with an admin account always show it.
Is it safe to download plugins from other websites?
Only from the official developer. Never install 'free' copies of paid plugins from download sites; they often contain malware and get no security updates.
How do I remove a plugin completely?
Deactivate it, then click Delete on the Plugins page. Some plugins leave settings in the database; check the plugin's settings for a cleanup option before deleting.
