Description | TIFF is a flexible image format that normally saves 8 or 16 bits per color (red, green and blue) for a total of 24 or 48 bits. TIFFs flexibility is both a feature and a curse, with no single reader capable of handling all the different varieties of TIFF files. TIFF can be lossy or lossless. Some types of TIFF files offer relatively good lossless compression for bi-level (black and white, no grey) images. Some high-end digital cameras have the option to save images in the TIFF format, using the LZW compression algorithm for lossless storage. The TIFF image format is not widely supported by web browsers TIFF is still widely accepted as a photograph file standard in the printing industry TIFF is capable of handling device-specific color spaces, such as the CMYK defined by a particular set of printing press inks. | 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. |
