JPEG

JPEG stands for Joint Photographic Experts Group, which is the name of the committee that created the standard. It refers to a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography.

Key Characteristics of JPEG:

• File Extension: .jpg or .jpeg
• Compression: Lossy, meaning some image quality is lost during compression to reduce file size.
• Best Used For: Photographic images and realistic scenes with smooth variations in tone and color.
• Not Ideal For: Images with sharp edges, text, or transparency (e.g., logos or line art).
• Color Support: Supports 24-bit color (16.7 million colors).
• Adjustable Quality: Compression level can be adjusted to balance image quality and file size.

JPEG is widely supported across all platforms and devices, making it one of the most popular image formats in use today.
