JPEG Format Full Form
- JPEG stands for Joint Photographic Experts Group.
Key Points:
Origin: The format was created by the Joint Photographic Experts Group, which is a committee of ISO (International Organization for Standardization).
Purpose:
- Designed for compressing digital images, particularly photographs.
Balances image quality and file size, making it ideal for web images and digital photography.
Compression:
- Utilizes lossy compression, meaning some image data is lost during compression to reduce file size.
This results in smaller files, which are easier to store and share.
Usage:
- Widely used in digital cameras, smartphones, and on the internet.
Commonly used for:
- Websites
- Social Media
- Email Attachments
File Extension: JPEG files typically use the .jpg or .jpeg file extension.
Advantages of JPEG:
- High Compression Ratios: Reduces file size significantly without major loss of quality.
- Wide Compatibility: Supported by almost all web browsers and image editing software.
- Versatile: Suitable for various applications, from online images to printing.
Disadvantages of JPEG:
- Loss of Quality: Repeated saving can degrade image quality due to its lossy nature.
- Limited Color Depth: Not ideal for images requiring high color fidelity, such as graphics or logos.
In summary, JPEG is a widely recognized format for digital images, particularly suited for photographs due to its efficient compression methods.
