PNG vs JPG (JPEG): Full Comparison
PNG and JPG are the two most common image formats on the web. PNG uses lossless compression and supports transparency, making it ideal for graphics, logos, and screenshots. JPG uses lossy compression for smaller file sizes, perfect for photographs and complex images where slight quality loss is acceptable.
