JPEG — The Reliable Workhorse
Best for photographs, hero images, and complex gradients. Universal compatibility. 30+ years of ecosystem maturity.
Quality sweet spot: 75-85% for web use. Quality 80 delivers excellent visual results at a fraction of original size.
PNG — The Precision Choice
Best for logos, screenshots, text overlays, and anything needing transparency. Lossless = pixel-perfect accuracy.
Pro tip: PNG-8 (256 colors) is 4-5x smaller than PNG-24 for simple graphics. Use it for icons and low-color images.
WebP — The Modern Standard
25-35% smaller than JPEG. 26% smaller than PNG. Supports both lossy and lossless, plus transparency and animation.
Browser support in 2026: 97%+ (all modern browsers).

- Need transparency? → WebP or PNG
- Pixel-perfect? → PNG or WebP lossless
- Social media? → JPEG (platforms recompress anyway)
- Printing? → PNG or TIFF
