Make your website faster than ever with TIO’s smart optimization.
Upload your images like you’ve always done before, and we’ll handle the rest. The Image Optimizer compresses your image and converts it to a modern file format. The result is the lightest image possible, without losing the quality.
Why choose our plugin?
The Image Optimizer uses smart optimization parameters tuned specifically for website images. It’s designed to be a simple companion that gives you the perfect image every time. We decide on the perfect balance of size and quality for your uploaded image. TIO automatically converts your new uploads to the best format (including modern formats like WebP and AVIF), applies lossless conversion or uses lossy compression settings that don’t affect the quality.
It’s perfect for small marketing teams who don’t have the time and know-how to optimise images manually and busy agencies who can’t afford the time to do it manually at scale.
We developed TIO to solve our own frustration with image optimizers. As a result, we were able to achieve results up to 35% file size reduction compared to other compressors. Going the extra mile helps ticking off the Google PageSpeed insights image checks, especially those for next-gen image formats.
How it works?
You upload your images as you normally do — one by one or in bulk, either way is fine. You can do it via the WordPress media library and by uploading directly into your pages.
We categorise what’s in the image to apply the right optimization settings. We use suitable compression and file format conversion, as well as remove unnecessary metadata.
As an example, screenshot compression makes sure to not sacrifice text sharpness, while plain illustrations with low colour depth use more aggressive compression since it won’t affect the quality nearly as much.
We optimise the source file, so WordPress thumbnails come pre-optimised as well.
Supported file formats
The only excluded file format is GIF. We support all other file formats that WordPress allows, including HEIC.
Try it for free
TIO allows you to generate one license key with 50 free image credits per website. That’s enough to test a few core pages and measure the impact.

<li>Paste the key in Settings > TIO Image Optimizer</li>

Credit restoration for peace of mind
Uploaded an image by mistake or we didn’t optimise it to your liking? You can reclaim the credit straight from the WordPress Media Library, subject to our <a href="https://theimageoptimizer.com/terms" rel="nofollow ugc">Terms</a>.
And if we notice that your image was already optimal, we won’t charge a credit in the first place — nothing to reclaim there!
External Service Disclosure
This plugin relies on The Image Optimizer API, a third-party service hosted at <code>api.theimageoptimizer.com</code>, to compress images. When you upload an image with auto-compress enabled, the plugin sends the image file and your site URL to this API. The API returns a compressed version of the image, which replaces the original in your media library.
No data is collected or stored beyond what is needed to process the compression request and manage your credit balance.

Perfect Images handles the basics of WordPress image management that should have been built-in from the start. Manage image sizes, disable the ones you don’t need, add custom sizes, and regenerate thumbnails in bulk. It’s the essential foundation every WordPress install needs for clean, efficient image handling.
Think of it as your image management base layer. WordPress creates too many sizes? Disable them. Need a custom thumbnail size? Add it. Want retina support or modern formats like WebP/AVIF? Enable those modules. Perfect Images gives you complete control without bloat.
Explore <a href="https://meowapps.com/wp-retina-2x" rel="nofollow ugc">our official site</a> and check out <a href="https://meowapps.com/wp-retina-2x/tutorial/" rel="nofollow ugc">the tutorial</a> to get started.
<h3>Core Features</h3>
⚙️ Image Size Management 
The foundation of everything. View all registered image sizes (WordPress defaults, theme sizes, plugin sizes), disable the ones you don’t need, and add custom sizes. Finally, control over those pesky WordPress-generated sizes like <code>medium_large</code>, <code>1536x1536</code>, and <code>2048x2048</code>.
🔄 Regenerate Thumbnails 
Bulk regenerate thumbnails after changing sizes or switching themes. Progress tracking, smart processing, and automatic cleanup of old unused sizes.
🖼️ Retina Images (Module) 
Optional module for high-DPI displays. Automatically generate and serve crisp @2x versions of your thumbnails. Works seamlessly with WordPress responsive images.
🎨 Modern Formats (Module) 
Optional WebP/AVIF conversion. Convert images to modern formats for smaller file sizes and faster loading—without replacing your originals.
🚀 Easy IO (Module) 
Optional CDN-based image optimization via EWWW. Automatically converts and delivers your images in WebP/AVIF, resizes on the fly, and serves them from a global CDN—zero server configuration required.
🤖 AI Features (Module) 
Optional AI-powered tools. Upscale images via Claid.ai when your source is too small, or use the AI Assistant to analyze your sizes and recommend which to enable or disable based on your theme’s srcset needs.
