WebP is a modern image format developed by Google that offers superior compression compared to PNG or JPG. When you convert PNG to WebP, you get smaller files that still keep transparent backgrounds and clean details. A lighter image means faster websites, less bandwidth, and better SEO performance. That’s why most web developers, designers, and e-commerce owners are switching from PNG to WebP today.

What PNG Files Do

PNG files are great for high-quality images with transparent backgrounds—perfect for logos, icons, web graphics, and digital designs. Unlike JPG, PNG uses lossless compression, so quality doesn’t degrade when edited and saved multiple times. The trade-off is size: PNGs can be heavy and slow pages down. Converting PNG to WebP keeps the same detail and transparency while making files smaller, faster, and more efficient for web use.
