<b>JPEG</b>: The Joint Photographic Experts' Group file format is a good Web file format but it uses lossy data compression.<p><b>PNG</b>: the Portable Network Graphics format is an extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. PNG is designed to work well in online viewing applications, such as the World Wide Web, so it is fully streamable with a progressive display option. Also, PNG can store gamma and chromaticity data for improved color matching on heterogeneous platforms.

<p><b>TIFF</b>: the Tagged Image File Format is a rather old standard that is still very popular today. It is a highly flexible and platform-independent format which is supported by numerous image processing applications and by virtually all prepress software on the market.

<p><b>PPM</b>: the Portable Pixel Map file format is used as an intermediate format for storing color bitmap information. PPM files may be either binary or ASCII and store pixel values up to 24 bits in size. This format generates the biggest-sized text files for encoding images without losing quality.

<p><b>BMP</b>: the BitMaP file format is a popular image format from the Win32 environment. It efficiently stores mapped or unmapped RGB graphics data with pixels 1-, 4-, 8-, or 24-bits in size. Data may be stored raw or compressed using a 4-bit or 8-bit RLE data compression algorithm. BMP is an excellent choice for a simple bitmap format which supports a wide range of RGB image data.
