- Adjustable quality vs. size trade-off
Limitations
- Lossy — quality drops on each re-save
- No transparency support
- Visible artefacts on text, lines and flat colour
Best for: Photographs and complex images for the web, email and social media where small file size matters most.

Strengths
- Outstanding compression and quality
- Wide colour gamut and HDR
- Transparency and animation support
