What type of image format is the standard for compressing image data and is the most common?

• A. PNG
• B. JPEG
• C. GIF
• D. TIFF

Answer: (B)

The main idea here is understanding which image format is optimized for compressing photographic data and widely used across devices and the web. JPEG is the format designed for compressing photos, using lossy compression to shrink file sizes significantly while keeping a visually acceptable quality. This balance makes it the default choice for cameras, editing software, and online images, so it’s the most common format you’ll encounter.

In contrast, PNG uses lossless compression and is better for images with sharp edges or transparency, but it usually results in larger files for photos. GIF is limited to 256 colors and is mainly used for simple graphics or animations. TIFF is a high-quality format favored for printing and archival work, not typical for everyday online use due to large file sizes. So JPEG best fits the idea of a standard, widely used image format for compressed photographic data.
