About PNG
Portable Network Graphics (PNG) is a raster graphics format that supports lossless data compression, meaning no quality is lost when the file is compressed. Its most notable feature is its support for transparency (the alpha channel), which allows images to have transparent backgrounds. This makes PNG a favorite for web graphics, logos, and icons.
About GIF
The Graphics Interchange Format (GIF) is one of the oldest image formats still in common use on the web. It's best known for its ability to create simple animations. GIF uses lossless compression but is limited to a palette of only 256 colors, which makes it unsuitable for complex photographs but great for simple graphics, logos, and of course, animated memes.

Frequently Asked Questions
Is PNG better than JPEG?
It depends on the use case. For photographs, JPEG provides smaller file sizes with minimal perceptible quality loss. For graphics with sharp lines, text, or transparency needs, PNG is superior as it is lossless and supports an alpha channel.
Why are PNG files larger than JPEGs?
PNG files are larger because they use lossless compression. They retain all the original image data, whereas JPEG uses lossy compression to discard data and reduce file size. This makes PNGs higher quality but also larger.
Why is GIF so popular for animations?
GIF's popularity for animations stems from its simplicity and universal browser support. It's an easy, lightweight way to display short, looping animations without needing plugins or video players. Modern formats like APNG or WebP offer better quality, but GIF's legacy and ease of use keep it relevant.
Can a GIF have more than 256 colors?
No, a standard GIF is limited to a 256-color palette for the entire animation frame. While techniques exist to simulate more colors through dithering, the fundamental limitation remains, which is why GIFs are not good for photographic content.
