FIX
6 issues found across 117 images
Warning::
9 images significantly larger than display size
Resizing to display dimensions could save approximately 0 KB.
Got: ~0 KB wasted
Warning::
3 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
5 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Warning::
All 2 images use legacy formats (JPEG/PNG/GIF)
WebP offers 25-35% smaller files than JPEG. Use <picture> with <source type="image/webp"> for modern format support.
Warning::
5 images missing alt text
Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
Info::
1 image(s) wider than 400px without srcset (no responsive serving)
These images deliver the same asset to every viewport (mobile, tablet, retina). Adding srcset / <picture> lets the browser pick a viewport-appropriate variant and typically saves 40-70% of bytes on mobile. Sample: data:.

Open Graph / Twitter Card Depth
2 OG/Twitter depth issue(s) detected
REVIEW
2 OG/Twitter depth issue(s) detected
Info::
og:image aspect ratio 0.92:1 (320×347) is outside Facebook's recommended ~1.91:1
Facebook's recommended OG image is 1200×630 (1.91:1 aspect ratio). The declared dimensions 320×347 give a ratio of 0.92:1, which Facebook will crop center-to-fit; the result often clips important content from the top/bottom or sides. Use a wider/taller image close to 1.91:1, or accept the cropping consequences.
Got: 0.92:1 (320×347)
Warning::
Twitter card is `summary_large_image` but OG image is 320×347 (ratio 0.92:1) -- closer to square
`twitter:card` is set to `summary_large_image` (the wide-image preview format), but the declared OG image dimensions (320×347, aspect ratio 0.92:1) are closer to square than wide. Twitter will crop the image to fit the wide format, often badly. Either: (1) provide a wider image (~2:1 ratio recommended; minimum 600×314, optimal 1200×630), or (2) change `twitter:card` to `summary` which uses a square thumbnail crop.
Got: 320×347 declared with summary_large_image card
