1. PNG format
PNG images store a single raster image in any color depth, a platform-independent format. PNG supports high-level lossless compression and supports alpha channel transparency. PNG supports gamma correction and interlacing.
2. JPEG format
JPEG is a lossy, direct color, bitmap image. The design goal of the JPEG image format is to compress the file size as much as possible without affecting the quality of the image that can be distinguished by humans. This means that JPEG removes part of the original information of the image, that is, it performs lossy compression.
The advantage of JPEG pictures is that they use direct colors. Thanks to richer colors, JPEG is very suitable for storing photos and expressing more vivid image effects, such as color gradients.
3. PDF format is an electronic publishing software used by Adobe for Windows, UNIX and DOS systems. Like Postseript pages, PDFs can contain vector and bitmap graphics and can also include electronic document search and navigation capabilities.
4. TIFF format
TIFF stores a single raster image at any color depth. TIFF can be considered the most widely supported graphics file format in the printing industry. TIFF supports optional compression and is not suitable for viewing in a web browser.
5. BMP format
The abbreviation of BitMap is a lossless bitmap that supports both indexed and direct colors. This is an older image format. BMP is lossless, but at the same time this picture format performs almost no data compression, so pictures in BMP format usually have larger file sizes.
