Image Optimization

PASS
2 images, 0 KB saveable
Warning::
https://www.google.com/images/branding/googlelogo/... is missing width/height — may cause layout shift
Set explicit width and height to prevent CLS.
2 images 3 KB
0 oversized -0 KB
2 legacy format
1 missing dimensions CLS risk

Set explicit width and height to prevent CLS.

Why this matters

Image without explicit width/height — browser can't reserve space; CLS jumps when image loads.
