Description | The PNG file format is regarded, and was made, as the free and open-source successor to the GIF file format. The PNG file format supports true color (16 million colors) whereas the GIF file format only allows 256 colors. PNG excels when the image has large areas of uniform color. The lossless PNG format is best suited for editing pictures and all popular modern browsers fully support PNG. | JPEG 2000 is a wavelet-based image compression standard. The aim of JPEG 2000 is not only improved compression performance over JPEG but also adding (or improving) features such as scalability and editability. | ||||||||||
Benefits | Lossless, popular, 16M colors | much smaller file size at equal quality than JPEG | ||||||||||
Drawbacks | Large files | less popular, requires more computational resources | ||||||||||
