When is it better to use PNG and WebP image formats, and when should you choose SVG?

• SVG (Scalable Vector Graphics) — for vector graphics (icons, logos). Advantages: scalable without loss of quality, smaller file size for simple graphics, easy to animate. Use when you need to maintain clarity at any size and have the ability to generate graphics programmatically.
• PNG (Portable Network Graphics) — for raster graphics with transparency. Advantages: supports alpha channel, lossless compression. Use for images where transparency is important or you need to preserve maximum quality without compression artifacts (e.g., screenshots, complex illustrations with text).
• WebP — for raster graphics. Advantages: better compression compared to JPEG and PNG (both lossy and lossless), supports transparency. Use for photographs and images where you need to minimize file size while maintaining acceptable quality. Preferable for most raster images if supported (Android 4.0+).

The choice depends on the type of image, the need for scaling, transparency availability, and file size requirements.
