Image optimization
Images are often the largest assets on any page and the primary cause of slow load times. Auditite analyzes every image on your site for file size, format efficiency, missing alt text, lazy loading implementation, and responsive image markup — then tells you exactly how to fix each issue.
Key capabilities
File Size Analysis
Identify oversized images with estimated savings. See exactly how many kilobytes each page could save by compressing or resizing images.
Format Recommendations
Detect images served in legacy formats (PNG, JPEG, GIF) that could be converted to WebP or AVIF for significant size reductions.
Alt Text Audit
Find every image missing alt text, detect duplicate or generic alt attributes, and flag alt text that does not describe the image content.
Lazy Loading Check
Verify that below-the-fold images use lazy loading and that above-the-fold images (especially LCP elements) are eagerly loaded.
Responsive Image Audit
Check srcset and sizes attributes to ensure images are served at appropriate dimensions for each viewport, preventing wasted bandwidth.
Dimension Attributes
Detect images missing width and height attributes that cause layout shifts (CLS) as the browser calculates dimensions during load.
How it works
Auditite catalogs every image on your site during the crawl, analyzing each one for size, format, attributes, and loading behavior.
-
Full image inventory
Every image is cataloged with its URL, file size, dimensions, format, alt text, loading attribute, and the pages where it appears.
-
Compression analysis
Each image is tested for potential compression savings — comparing current size against optimized versions in WebP and AVIF formats.
-
Page impact scoring
Issues are ranked by their impact on page load time and Core Web Vitals, so you know which images to optimize first.
-
Actionable fixes
Get specific recommendations per image — target dimensions, suggested format, compression level, and the HTML attributes to add or change.
