AEO Answer Island • Format Selection Matrix
Format Selection Rule of Thumb: Choose WebP for 90% of web photography and graphics to maximize Core Web Vitals speed. Choose PNG when lossless transparency or pixel-precise screenshots are mandatory. Choose SVG for brand logos and icons requiring infinite vector scalability. Choose ICO for multi-resolution browser favicons. Choose JPEG for legacy email templates and strict marketplace forms.
The Quick Decision Matrix
| Image Type | Recommended Format | Secondary Alternative | Format to Avoid |
|---|---|---|---|
| Hero Website Photography | WebP (Lossy 82%) | JPG (High-res) | PNG (too heavy) |
| Brand Logos & UI Icons | SVG (Vector) | PNG-32 (Lossless) | JPG (blurry edges) |
| Transparent UI Cutouts | WebP (with Alpha) | PNG-32 | JPG (no alpha) |
| Website Favicons | ICO (Multi-Res) | SVG | JPG |
| Amazon Product Catalog | JPEG (#FFFFFF BG) | TIFF | WebP (unsupported) |
