Name three web-graphic formats and describe their strengths and weaknesses.

Name three web-graphic formats and describe their strengths and weaknesses.

• A. JPEG: photos, lossy; PNG: lossless with transparency; SVG: scalable vector for UI.
• B. TIFF: photos, always lossy; BMP: supports transparency; GIF: vector graphics.
• C. WEBP: audio format; SVG: raster; JPEG: grayscale only.
• D. PNG: video encoding; SVG: bitmap; JPEG: vector

Answer: (A)

Understanding how web image formats balance quality, file size, and features helps you choose the right format for a given task. The best combination here matches three common formats with their real strengths and typical uses. JPEG is designed for photos and uses lossy compression to reduce file size, which keeps images manageable on the web but can introduce artifacts and soften detail in high-contrast areas. PNG uses lossless compression and supports transparency (alpha channel), making it ideal for graphics with crisp edges, text, and UI elements where clean lines matter, though it can result in larger files for complex photos. SVG is vector-based, so it scales without pixelation and is perfect for icons, logos, and illustrations that need to render crisply at any size; it isn’t suitable for detailed photographic imagery. Other options mix properties that don’t align with how these formats actually work—TIFF isn’t restricted to lossy and can be lossless; BMP isn’t typically used for transparency; GIF is raster and limited in color and features; WEBP is an image format, not audio, and SVG is vector, not raster; JPEG is not limited to grayscale.
