FIX

2.7 MB transferred, 35 requests

Page weighs 3.2 MB (2.7 MB transferred)

Images are 2.2 MB — compress or use modern formats

Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.

Got: 2.2 MB

Fonts are 289 KB — consider subsetting or using system fonts

Subset fonts to include only used characters, or switch to system font stacks.

Over budget

Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.

Why this matters

Image bandwidth is high — modern formats (WebP/AVIF) and resizing typically cut it 50%+.

Subset fonts to include only used characters, or switch to system font stacks.

Why this matters

Font payload is large — subset to used glyphs only, or fall back to system fonts (zero load time).
