Which file format is commonly used for images?

• A. PDF
• B. JPEG
• C. DOCX
• D. HTML

Answer: (B)

The JPEG file format is widely recognized and commonly used for images, particularly photographs and complex images that require a balance between quality and file size. JPEG, which stands for Joint Photographic Experts Group, employs lossy compression techniques, allowing for reduced file sizes without significantly compromising visual quality. This makes it ideal for web use, social media, and digital photography, where a smaller file format is desirable for faster loading times while still retaining acceptable image quality.

In contrast, PDF (Portable Document Format) is designed primarily for documents, preserving text formatting and graphics for printing and sharing. DOCX is a word processing format used by Microsoft Word, primarily for text-based documents rather than images. HTML (Hypertext Markup Language) is not an image file format; rather, it is the standard markup language used to create and design web pages and applications, facilitating the inclusion of various types of media, including images. Therefore, JPEG stands out significantly as the go-to format for images.
