Keeping your WordPress site secure is super important—not just for you, but for your visitors too. One of the easiest ways to build trust and protect data is by using an SSL certificate. It makes sure any info shared on your site stays safe and lets people know they’re in good hands. But here’s the thing: just having an SSL certificate isn’t enough if it’s not set up the right way.
That’s where SSL plugins come in. Over the years, I’ve learned just how helpful these plugins can be. They take care of the technical stuff—like forcing your site to use HTTPS and fixing those annoying mixed content warnings—so you don’t have to stress about it.
With so many plugins out there, I know it can be tricky to choose the right one. That’s why I put together this guide. I’ve rounded up the best SSL plugins for WordPress to help you secure your site without the hassle.

With over five million active installations, Really Simple SSL is hands down the most popular SSL plugin in the WordPress world—and for good reason. It makes setting up SSL a breeze, which is why it’s perfect for both beginners and experienced users.
This plugin automatically detects your SSL certificate and sets your site to load over HTTPS without you having to lift a finger. One of the reasons I love it is that even the free version is packed with great features. It tackles annoying issues like mixed content that can cause browser warnings if not fixed. For most users, the free version is more than enough to turn your site into a secure HTTPS environment.

It also includes extra features like server health checks and vulnerability detection for plugins and themes, making it a solid choice for improving your site’s security.
WP Encryption
WP Encryption is a great plugin if you’re looking for a straightforward way to secure your site, especially if you want the convenience of automated tools.
With WP Encryption, even the free version lets you generate SSL certificates through Let’s Encrypt—perfect if you’re just getting started. However, you’ll need to manually install the certificate via your cPanel, which might be a bit tricky for some users. The good news is, the premium version makes things a lot easier by automating the entire installation process, saving you time and hassle.
The free version also has useful features like forcing your site to load over HTTPS and scanning for mixed content. But, if you want to actually fix those mixed content issues, you’ll need to upgrade to the premium version.

The free version also includes features like forcing your site to load over HTTPS and scanning for mixed content. But to fix those mixed content issues, you’ll need to go for the paid version. If you’re managing multiple sites or want a more hands-off solution, WP Encryption’s premium features offer a convenient all-in-one SSL management option.
WP Force SSL
WP Force SSL may not have all the extra features that plugins like Really Simple SSL or WP Encryption offer, but it does exactly what it promises—forces your site to use HTTPS instead of HTTP.
If you already have an SSL certificate set up (like one from your hosting provider or Let’s Encrypt), WP Force SSL will make sure your entire site loads over HTTPS and even enables HSTS for extra security. However, the free version is a bit basic—it can scan your site for issues, but if you want to fix mixed content problems or generate and install SSL certificates, you’ll need to upgrade to the premium version.
Key Features
- Scans your site for mixed content issues and helps fix them
- Monitors your site and SSL status in real-time so you know if anything goes wrong
- Lets you generate and install SSL certificates (premium feature)
- Includes a license manager if you’re using it on multiple sites
Pros

If you already have an SSL certificate (from your hosting or Let’s Encrypt), this plugin will automatically redirect your site to use the secure version. It also comes with helpful tools like scanning for mixed content issues, keeping an eye on your SSL status in real-time, and even letting you turn on extra security (HSTS) for free.
Overall, WP Force SSL is a good option if you just need something simple to force HTTPS and don’t need a bunch of extra features. It’s a clean, no-frills plugin that does what it says without getting too complicated.
SSL Zen
If you’re looking for a plugin that can both create and install an SSL certificate, SSL Zen is a great option—especially if you’re on a budget. It lets you set up a free SSL certificate using Let’s Encrypt right from the free version, which saves you from having to buy one separately.
One thing to keep in mind: the setup isn’t completely hands-off. You’ll need to do a few technical steps, like verifying your site through your hosting panel or DNS settings. It’s not too hard, though—SSL Zen gives you step-by-step videos to help you through it.

One Click SSL
One Click SSL is a straightforward and beginner-friendly plugin that helps you switch your WordPress site to HTTPS with minimal fuss. Despite the name, it takes two quick clicks—one to check for SSL support and another to turn it on. Still, it’s super simple and does a great job making the process smooth.
You’ll need to have your SSL certificate already set up through your hosting provider or another source, as the plugin doesn’t handle that part. But once that’s done, One Click SSL automatically redirects your site to HTTPS and helps clean up any mixed content issues.
Key Features

- Scans your site for mixed content issues that could prevent the padlock from showing
Pros

- Clean interface that doesn’t overwhelm you with options

Pricing
Free
Summary
If you’re just looking for a quick and easy way to switch your WordPress site to HTTPS, One Click SSL might be exactly what you need. It doesn’t try to do too much — it simply checks if your SSL certificate is already in place and helps you flip the switch to enable it site-wide.
Once activated, it automatically redirects all your traffic to HTTPS and even scans for mixed content issues that might mess with your site’s padlock icon. It’s not packed with advanced features, but that’s kind of the point — it’s built for simplicity.
Easy HTTPS Redirection
If you just want a simple way to make sure your WordPress site uses HTTPS, Easy HTTPS Redirection does exactly that—without any extra fluff. It’s super straightforward and easy to set up, but keep in mind, you’ll need to have an SSL certificate already installed (your hosting provider can usually help with that).
What I like about this plugin is how lightweight it is. It sticks to one job: redirecting your site (or just certain pages, if you want) to HTTPS. It also helps make sure your images, scripts, and other static files load securely—so you avoid those annoying mixed content warnings and keep the padlock showing in the browser.
Key Features

Summary
Easy HTTPS Redirection doesn’t try to do everything—just one thing well: redirect your visitors to the secure version of your site. You’ll need to already have an SSL certificate installed, but once that’s set, the plugin helps force your site (or specific pages) to load securely. It also makes sure things like images and scripts are loaded over HTTPS, which helps avoid that annoying “not secure” warning in browsers.
Overall, this plugin is perfect if you want a simple, lightweight tool to redirect your site to HTTPS without any extra features getting in the way. It’s great for those who like to keep things clean and straightforward.
Free SSL Certificate
Free SSL Certificate is one of the few free plugins that actually lets you both generate and install an SSL certificate—no need to grab one separately. That’s a big win if you’re on a budget. Just keep in mind that the free version shows ads, which might be a bit annoying for some.
There’s no direct support unless you upgrade, so you’ll be relying on the forums if anything goes wrong. But if you decide to go premium, you get automatic renewals, better support, and even Cloudflare integration to help protect your site and boost speed.
