Image Optimisation

← Back to all features

Alt Text Analysis

Missing alt text is both an accessibility failure and a missed SEO opportunity:

• Find images missing alt text — an accessibility and SEO issue
• Review alt text quality and descriptiveness
• Identify decorative images that should have empty alt attributes
• Recommendations for writing effective alt text

Size Analysis

Oversized images are the most common cause of slow page loads:

• Detect oversized images that slow down your pages
• Estimate potential savings in KB/MB for each image
• Identify images that should be compressed or resized
• Total page weight analysis with image contribution breakdown

Format Recommendations

Modern image formats can dramatically reduce file sizes without visible quality loss:

• Suggest modern formats (WebP, AVIF) where appropriate
• Identify images still using legacy formats (BMP, unoptimised PNG)
• Estimated savings from format conversion

Lazy Loading

Lazy loading defers off-screen images, improving initial page load speed:

• Check which images use lazy loading
• Identify above-the-fold images that should NOT be lazy loaded
• Detect missing lazy loading on below-fold images
