With a 4.8/5 rating.

Everything you need to optimize images and speed up your site.

Works out of the box with no complicated setup.

Compress images without losing quality

Reduce image file sizes automatically while keeping your images sharp and clear. Smush lets you compress images using both lossless and lossy compression, so you get the best balance of quality and performance without extra work.

You can also compress images outside the media library using Directory Smush, making it easy to optimize images stored in theme folders, plugins, or other directories on your server.

Lazy load images for faster pages

Enable image lazy load across your site so images load only when needed. This improves initial page speed and creates a smoother experience for visitors without extra configuration.

Serve WebP and AVIF images automatically (PRO)

Convert images to WebP and AVIF and serve them automatically to supported browsers. Smush helps you optimize images using next-gen formats to reduce file size and improve load times across your WordPress site.

Deliver images faster with an Image CDN (PRO)

Serve images through a global image CDN to reduce latency and improve load times for visitors around the world.

119 global CDN servers
Up to 500 GB of bandwidth
Faster image delivery based on visitor location
Improved performance for image-heavy and high-traffic sites

Automatically resize and fix image dimensions (PRO)

Eliminate common PageSpeed warnings and improve layout stability with automatic image sizing. Smush dynamically resizes images to perfectly fit their containers, regardless of original size, helping fix the “Properly size images” warning in Google PageSpeed Insights.

It also automatically adds missing width and height attributes to your images, improving rendering speed and reducing layout shifts. This helps you meet the “Ensure images have explicit width and height” recommendation without any manual work.

Часто задаваемые вопросы

How do I optimize images in WordPress with Smush?

Smush makes it easy to optimize images in WordPress automatically.

Once installed, Smush will optimize images and compress images as you upload them. You can also bulk optimize images already on your site with one click.

How do I compress images without losing quality?

Smush lets you compress images using both lossless and lossy compression.

This means you can reduce file sizes and improve performance without noticeable quality loss.

Can Smush serve images through an image CDN?

Yes. Smush Pro includes a global image CDN.

119 global CDN servers
Up to 500 GB of bandwidth
Faster delivery based on visitor location

This helps improve load times for users around the world.

How do I fix “properly size images” in PageSpeed Insights?

This warning means images are larger than the space they are displayed in.

Smush includes automatic image resizing, which dynamically resizes images to fit their containers. This helps eliminate the “Properly size images” warning without manual work.

How do I fix “images missing width and height” warnings?

Smush can automatically add missing width and height attributes to your images.

This improves rendering speed, reduces layout shifts, and helps you pass Core Web Vitals checks like CLS.

Can Smush convert images to WebP and AVIF?

Yes. Smush can convert images to WebP and AVIF formats to reduce file size and improve performance.

These next-gen formats help you optimize images and meet modern PageSpeed recommendations.

Why does PageSpeed say “serve images in next-gen formats”?

This means your images are not using WebP or AVIF.

Smush helps you convert images to these formats so they load faster and improve your PageSpeed score.

Удаляет ли Smush мои исходные изображения или заменяет их?

No. Smush does not delete your original images.

It compresses and optimizes resized versions by default. Full-size image compression is available in Smush Pro.

Why aren’t some images being compressed?

In the free version, images over 5MB are skipped.

Smush Pro supports compressing images up to 256MB.

Do I still need Photoshop to optimize images?

No. Smush automatically optimizes images across your entire site, including images added by plugins and themes.

What is the difference between optimize images and compress images?

Compressing images reduces file size. Optimizing images includes compression plus resizing, format conversion, and delivery improvements.

Smush handles both automatically.

Good plugin for compressing images in WordPress. Setup took just a minute, and it started optimizing right away. Site speed improved a bit, too. tnx devs for this.

cityneil 26.01.2026 1 ответ

I needed a lot of images optimised and Smush did the job. Will probably go to Pro level to get some of the additional features.

Smush helps reduce image size without losing quality. It improves site speed and works automatically in the background.

Kazam Creative 15.01.2026 1 ответ

Sorry it’s a deal-breaker for us as well. As others have also said, we’ve used this plugin on many websites for years and it’s served its purpose well, but now that you’ve restricted access to (almost) all the features unless we register for an account, we won’t be installing/using this plugin any more. It’s made it way too complicated to now have to register a new account every time we want to use it on another website.
