Portable Network Graphics

Portable Network Graphics

• A. .PNG
• B. .GIF
• C. .BMP
• D. .JPEG/.JPG

Answer: (A)

Portable Network Graphics is an image format known by its abbreviation PNG, typically saved with the .png extension. The key reason this is the right match is that PNG uses lossless compression, which preserves every detail of the image, and it also supports transparency through an alpha channel. That combination makes PNG ideal for web graphics, logos, and images with text where clarity and the ability to place the image over varying backgrounds matter. Other common formats differ in important ways. GIF does support transparency but is limited to a small color palette, which isn’t ideal for photos or graphics with many colors. BMP is a simple bitmap format that often results in larger file sizes and lacks efficient compression. JPEG uses lossy compression, which can blur details and does not support transparent backgrounds, making it unsuitable for images that require crisp edges or transparency.
