JPG and PNG image formats are essential for optimizing visual content on modern websites. JPG (JPEG) is best suited for photographs and complex images because it uses lossy compression to reduce file size, helping pages load faster and improving SEO performance. In contrast, PNG (Portable Network Graphics) offers lossless compression, making it ideal for graphics, logos, and images requiring transparency and sharp details. Choosing between JPG and PNG depends on the purpose—use JPG for speed and smaller files, and PNG for quality and clarity. Proper use of these formats enhances user experience, boosts page speed, and supports better search engine rankings.
