JPG is described as commonly used for what?

• A. Photos
• B. SVG
• C. Commercial Printing
• D. Large Document Format

Answer: (A)

JPEG is designed for photographs because its compression is lossy and tuned to natural images with smooth color transitions. This approach greatly reduces file size while preserving how colors blend in real scenes, making it the practical default for photos we share online or store on devices. It supports many colors (24-bit color) and can be saved at different quality levels, including progressively loading so images appear faster as they load. However, it doesn’t handle transparency and can introduce compression artifacts if pushed too far, so it’s not ideal for sharp-edged graphics or master printing where perfect fidelity is needed. By contrast, SVG is vector-based and scales without loss, which suits logos and line art, while printing workflows often prefer lossless formats like TIFF or PDF for the highest quality.
