Why do images use different formats?
Show answer & explanation
Answer: Different needs for quality/size
Different needs for quality/size ✓ — Correct! Image formats balance quality vs file size: (1) JPEG—lossy compression, small files, photos. (2) PNG—lossless, supports transparency, graphics/screenshots. (3) GIF—animation, limited colors. (4) WebP—modern, efficient, both lossy/lossless. (5) RAW—uncompressed, professional photography. Use case matters—web needs small files, printing needs high quality!
Monitor compatibility varies — Wrong. Modern monitors support all common formats. Format choice depends on balancing quality, file size, transparency, and use case.
Prevent unauthorized copying — Wrong. Formats aren't copy protection—they improve compression. JPEG for photos, PNG for transparency, GIF for animation, balancing quality and size.
