| A. GIF doubled in size for standard image, 6.7KB => 13.2 | |
| - fully supported | |
| - no gains for standard images without significant blocks of color | |
| B. WebP was reliably 2/3 original size. 26.3KB => 17.8 | |
| - only works in Chrome/Opera, Firefox is considering support but I wouldn't count on it | |
| - would require backfilling webp data (but for large/trafficked orgs this could be worthwile) | |
| - JS side - detect chrome/opera, change AWS extension to .webp | |
| - Save on AWS feeds, speed up lazy loading and UX considerably | |
| - Couldn't find a functional polyfill for unsupported browsers (webp-hero package) | |
| - Don't want conditional responses (one persion receives one extension, another a different extension) from the API, so would prefer to keep on front end | |
