Website Image Optimizer
Faster pages start with smaller images
Images are usually the biggest contributor to page weight. Optimize hero banners, blog images, thumbnails, and product shots for the dimensions your site actually renders them at.

A photo straight off a modern phone camera can be 4000px wide and 4-8 MB — served at those dimensions on a blog post that displays it at 800px, you're shipping 5-10x more data than the page needs. That gap is one of the most common, most fixable causes of slow page loads and poor Core Web Vitals scores.
This tool matches output dimensions to how images actually get used on a page — a hero banner needs to be wide but not print-resolution; a blog inline image rarely needs to exceed 1200px; a thumbnail can be tiny. Pick a preset that matches your use case, or set a custom maximum width, and compression and format selection are handled automatically alongside the resize.
The WordPress-optimized preset matches WordPress's common default content width so images look sharp without being needlessly oversized in your media library.
Frequently asked questions
Will this make my site load noticeably faster?
For most sites, images are the largest portion of total page weight, so right-sizing and modern-format conversion (WebP/AVIF) typically produces the single biggest page-speed improvement available without changing code.
Will my images get blurry if I set a maximum width?
No — maximum-width mode only shrinks images that are larger than the cap and preserves aspect ratio; it never enlarges an image that's already smaller than your limit.
Do you support retina (high-DPI) images?
Yes, the Retina preset targets 2x pixel density so images stay crisp on high-DPI displays while still being compressed efficiently.
