About the formats
JPEG image
JPG (JPEG) is the most widely used photo format on the web. Its lossy compression shrinks photographs to small files that open everywhere, from browsers to cameras and phones.

- Opens on virtually every device and app
- 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.
Icon (ICO)
