Smart Compression
Deliver Perfect Balance Between Speed and Quality for Every Image
What Is Smart Compression?
Smart Compression is an intelligent image optimization engine inside CompressX pro that gives you total control over how your images are compressed — by image roles (WordPress Standard Image Types or WooCommerce Image Types) and image sizes.
Designed for WooCommerce Stores
Instead of a one-size-fits-all approach, you decide what matters most:
- Razor-sharp quality where you need to convert.
- Speed-boosting file reductions where performance is key.
For WordPress Sites (WooCommerce stores), this means:
CompressX Pro doesn’t just compress your images — it understands your images.
How Smart Compression Works
1. Global Compression Level (Free Version Behavior)
Set a single compression level that applies to all images on your site.
Example: 80% quality for every image, regardless of type or size.
✅ Simple, quick setup — works out of the box.
2. Style-Specific Compression Overrides (Pro Feature)
Override the global setting for specific image types or roles:
- Use higher quality for WordPress featured images (they’re more visible).
- Use smaller sizes for WooCommerce product thumbnails (to speed up browsing).
✅ Tailors compression based on image purpose.
3. Size-Based Compression Adjustments (Pro Feature)
Apply preset compression offsets based on image pixel dimensions:
- Larger images get stronger compression to reduce file size.
- Smaller images get lighter compression to preserve detail.
✅ Automatically balances speed and clarity. Learn more…
Why Your Site Needs Smart Compression
(With Aware- & Size-Aware Image Compression)
Different Images Serve Different Purposes
Smart Compression lets you apply role-specific rules, ensuring each image is optimized based on what it does, not just how big it is.
Image Size Shouldn’t Dictate Quality Alone
-
A 300px thumbnail can tolerate aggressive compression.
-
A 1200px full-width banner must maintain brand impact.
-
Two images might be the same size but have different jobs — they shouldn’t be compressed the same.
Built for WooCommerce Workflows
Each of these image roles deserves a different compression strategy.
Smart Compression detects these and applies the right logic automatically — or lets you customize it.
Boost Performance Where It Counts Most
-
Apply smart balance for category and product listings.
-
Preserve high-quality visuals on conversion-focused product pages.
Better Experience Across Devices
Smart Compression dynamically fits image optimization to each type/size of images — improving UX, SEO.
Saves Time, Scales Intelligently
Whether you manage 50 or 5,000 images, set up once. Smart Compression adapts in real-time to every new image based on its role, and size.

Did the job with a minimum of effort
Although I am using a Cloudflare Worker with Cloudlare Transformations for image delivery, Google Pagespeed was still complaining about using unoptimised formats on my home page featured image. A quick run of this plugin completely solved the issue with a minimum of fuss.
The only webp / avif plugin you’ll ever need
I registered so I can write the review, the plugin works absolutely flawlessly. If you are trying to decide between all the plugins for webp / avif support you can stop, I did it for you and this is the one you need.
Much love, thanks for your work <3
Very useful and practical
Easy to use and verify, images are actually getting converted to webp which is a good sight, thank you for this wonderful plugin
Great and simply
Simple to use, no difficulty in settings, does its job well. Compresses images to webp and avif, and also creates the whole series of thumbnails.
Remarkable work
This plugin does the job it advertises and does it well. The site’s pages use reduced images and it’s very effective. The reduction work takes time if you have a large stock but then it’s done as you go along.
Well done to the developers
