About PNG
PNG is a lossless image format that supports full transparency (alpha channel). It was created as a patent-free alternative to GIF and is the preferred format for logos, icons, screenshots, and graphics that require transparency.

- Ideal for graphics, logos, and screenshots
- No patent restrictions
Limitations
- Larger file sizes than JPEG for photographs
- No animation support (use APNG instead)
- Not optimal for large photographic images
- Slower to decode than JPEG
About JPEG

Advantages

- Universally supported across all browsers and devices
- Small file sizes ideal for web and email
- Adjustable compression quality (1-100)
Limitations
- Lossy compression degrades quality with each save
- No transparency support
