Key Points
- JPEG stands for Joint Photographic Experts Group, which is the name of the committee that created the standard in 1992.
- It is a commonly used method of compressing digital images, especially for photographs, to reduce file size while maintaining image quality.
- JPEG is a lossy compression format, meaning some data is discarded to achieve smaller file sizes.
- This format is widely used in digital cameras, online image sharing, and web design due to its balance between quality and compression.
- JPEG supports 24-bit color, allowing up to 16.7 million colors, making it suitable for realistic images and photographs.
Additional Information
- Compression Types in JPEG:
- Lossy Compression: Reduces file size by removing some image data, leading to a slight loss in quality, especially noticeable at higher compression levels.
- Baseline JPEG: The standard JPEG format used universally for image compression.
- Alternatives to JPEG:
- PNG (Portable Network Graphics): A lossless compression format, ideal for images requiring transparency.
- GIF (Graphics Interchange Format): Supports animations but uses a limited color palette (256 colors).
- WebP: A modern image format that provides superior compression compared to JPEG and PNG.
- Applications of JPEG:
- Used in digital photography and image storage on devices like cameras, smartphones, and computers.
- Widely used for online image sharing and web design due to its smaller file sizes.
- Preferred for email attachments and social media uploads where bandwidth is a concern.
- Limitations of JPEG:
- Not suitable for images requiring transparency or high precision, such as logos or icons.
- Repeated editing and saving of JPEG images can lead to cumulative quality loss due to its lossy nature.
