The 8 Best WebP Plugins for WordPress (2026 Comparison)

Faster websites rank higher, convert better, and keep visitors around longer. One of the simplest ways to speed up your site is by using WebP, a next-gen image format that can reduce file sizes without losing significant quality.

Manually converting images takes time, though. WebP plugins handle it automatically, turning your existing images into lightweight WebP files and serving them to compatible browsers. This results in a faster, smoother experience for your visitors and better performance metrics for you.

In this guide, we’ll compare the best WebP plugins for WordPress in 2026, from free converters to premium optimization tools. You’ll see how each tool handles image compression, browser fallbacks, CDN support, and setup.

1. Jetpack Boost

Jetpack Boost is a lightweight, one-click tool that helps WordPress site owners improve Core Web Vitals and front-end speed without requiring technical setup. It’s supported by Automattic, the people behind WordPress.com.

Key features

• A built-in image CDN that automatically serves images in WebP 
• A performance dashboard that displays mobile and desktop speed scores powered by Lighthouse metrics
• Automatic Critical CSS generation to prioritize above-the-fold content and speed up visual loading
• Page caching that serves static versions of pages for faster delivery
• JavaScript deferral to delay non-essential scripts and improve first contentful paint
• CSS and JS concatenation to reduce the number of HTTP requests
• A global image CDN that delivers images in modern formats, including WebP, for faster load times
• Advanced image quality controls, lazy loading, and resize options available on paid plans
• Performance history charts and insights to monitor improvements over time

Pros

• Built by Automattic, Jetpack Boost is a safe, reliable plugin that was created specifically for WordPress sites.
• It enhances image delivery, optimizes CSS and JavaScript, and includes caching for a full front-end performance lift.

Cons

• The free version locks advanced features like automated Critical CSS regeneration and image quality controls behind the premium plan.
• Using it alongside other optimization plugins may cause conflicts with overlapping features like caching or minification.
• Jetpack Boost focuses on front-end performance rather than server-level or database optimization.

Ease of use

For beginners, Jetpack Boost is the go-to option. The dashboard shows a “speed score” and each optimization is as simple as a toggle switch. Because of that, it works especially well for writers, marketers, or site owners who don’t want to manage lots of technical settings.

Pricing

• The Free plan includes core performance tools like Critical CSS generation, JavaScript deferral, caching, and a built-in Image CDN with WebP support.
• The Premium plan adds automated Critical CSS, image quality controls, and performance tracking. It starts at $9.95 per month (billed annually) for the first year and renews at $19.95 per month.

2. Converter for Media

Converter for Media is a plugin designed specifically to optimize and serve images in modern formats like WebP and AVIF on WordPress sites. It’s open source, widely used, and regularly updated.

Key features

• A Media Library converter that turns images into WebP or AVIF formats with one click
• Automatic conversion of new images uploaded to your media library
• Full browser fallback support
• WP-CLI support to run bulk conversion commands via the command line

Pros

• This plugin focuses purely on image format conversion.
• It supports browser fallbacks automatically, so you don’t need to worry about older browsers not displaying images correctly.
• It allows bulk conversion of existing media and tags along with automatic conversion of new uploads.
• It covers non-standard directories (including themes and plugins) as well as uploads, which means more complete coverage across your site’s images.

Cons

• Because the free version does not include AVIF output, you’ll need to upgrade to the Pro version for that next-gen format.
• If your images are hosted off-site, full compatibility is not guaranteed. 
• While the plugin handles format conversion, it doesn’t include broader performance tools.

Ease of use

Converter for Media is quite accessible, even for non-technical site owners. New uploads are handled automatically thereafter. Advanced users will appreciate the WP-CLI support and directory exclusion filters.

Pricing

• The free version provides WebP conversion for existing and new images, directory support, browser fallback, and WP-CLI commands.
• The Pro version enables AVIF output, quality control settings, and additional advanced features with pricing that starts at $5 per month for up to 10,000 images. 

3. Smush Image Optimization

7. TinyPNG

TinyPNG (also known as Tinify) powers one of the web’s most popular image compression APIs. Its WordPress plugin brings that same powerful engine to your site, automatically shrinking images without noticeable quality loss.

• Because it relies on an external API, usage depends on Tinify’s servers and pricing model.

Ease of use

TinyPNG is simple for anyone to use. Install it, enter your API key, and it immediately begins optimizing new uploads. You can also bulk optimize existing media with one click. 

Pricing

• The free plan includes 500 image compressions per month. With multiple WordPress image sizes, that typically covers about 100 uploads per month.

Factors to consider when choosing a WordPress WebP plugin

When comparing WebP plugins, look for features that improve speed and usability alongside the basic file conversion process, such as:

• Compression quality: Choose a plugin that reduces file size without noticeable quality loss and offers adjustable compression levels.
• Ease of setup: Prioritize tools that work immediately, with simple dashboards or one-click automation.
• Browser compatibility: Make sure the plugin provides automatic fallbacks for browsers that don’t support WebP.
• CDN or offload options: For image-heavy sites, CDN delivery or cloud offload ensures faster load times worldwide.
• Pricing and scalability: Free plans suit small sites, but paid tiers often include automation, AVIF conversion, and higher quotas.
• Extra performance features: Plugins like Jetpack Boost also handle caching, lazy loading, and Core Web Vitals optimization, which works great if you prefer an all-in-one solution.

Frequently asked questions 

Still unsure which WebP plugin to choose or how these tools actually work? Below are answers to some of the most common questions about WebP, browser support, and image optimization in WordPress.

What is WebP?

WebP is a modern image format developed by Google that provides high-quality compression for photos and graphics. It reduces file size significantly compared to JPEG and PNG, helping pages load faster without losing visual detail.

Is WebP supported by all major browsers?

Yes, WebP is supported by nearly every modern browser, including Chrome, Firefox, Edge, Safari, and Opera. Older browser versions may not display WebP images, which is why fallback support in your plugin is important.

What is a WordPress WebP plugin?

A WebP plugin automatically converts your existing images into lighter formats like WebP (and sometimes AVIF). It replaces large media files with optimized versions that load more quickly on all devices.

What are the main benefits of installing a WebP plugin?

WebP plugins help your website load faster, consume less bandwidth, and improve your Core Web Vitals scores. Faster load times also create a better user experience and can lead to higher search rankings.

Do I need coding knowledge to use WebP plugins?

No. Most WebP plugins, including Jetpack Boost, are designed for beginners. They use one-click setup processes or toggle-based dashboards, so you can optimize images without touching code.

Will WebP plugins slow down my website?

Typically, no. When used correctly, they actually make your website faster. However, installing multiple performance plugins with overlapping functions can cause conflicts. Instead, choose one well-built plugin from a reputable developer.

What happens if I deactivate a WebP plugin?

Your existing WebP files will remain on your server, but your site may revert to serving original formats (like JPEG or PNG) unless the plugin’s settings specify otherwise. Check each plugin’s documentation before deactivating.

What is the best WordPress WebP plugin?

The best all-around choice for most WordPress sites is Jetpack Boost. It handles WebP conversion and optimizes CSS, JavaScript, and caching to improve your overall site performance.
