Lossless-Looking Image Compression: Practical Ways to Speed Up Pages
Images are often the largest resource on a page. Reasonable compression noticeably speeds up loading with barely visible difference — directly affecting bounce rate and SEO.
Lossy vs lossless
- Lossy (JPEG/WebP) is smaller — good for photos
- Lossless (PNG) keeps detail — good for icons/screenshots
- WebP usually beats JPEG/PNG
