Convert PNG to PJPEG

Understanding PNG and PJPEG file formats

PNG (Portable Network Graphics) is a popular raster image format known for its lossless compression and support for transparency. It is widely used for web graphics, logos, and images requiring high quality and transparent backgrounds.

PJPEG (Progressive JPEG) is a variant of the standard JPEG format. It allows images to be displayed in successive waves of increasing detail, making them appear to load faster on slow connections. PJPEG is commonly used for web images where progressive rendering is beneficial.

Why convert PNG to PJPEG?

Converting PNG to PJPEG is useful when you need to reduce file size for faster web loading and do not require transparency. PJPEG's progressive loading enhances user experience on websites, especially with large images.
