Understanding the PNG format

Portable Network Graphics (PNG) is a widely used raster-graphics file format that supports lossless data compression. It natively supports 24-bit RGB or 32-bit RGBA colors, meaning it can perfectly handle transparent backgrounds. While PNG files are generally larger than JPEGs because they retain 100% of their original visual quality, it remains the absolute best format for web graphics, logos, and high-quality digital art.

Everything you need to know about WebP

WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. WebP lossless images are roughly 26% smaller in size compared to PNGs, while WebP lossy images are 25-34% smaller than comparable JPEGs. Using WebP allows developers to create smaller, richer images that make the web significantly faster, and it natively supports transparency without bloating the file size.
