There are many different formats of pictures, the most common ones are pictures in JPG, Gif, PNG, BMP format, each picture format has its own advantages. Sometimes a specific picture format is required according to different needs, or a certain picture format file is too large and takes up more space, and a smaller picture can be obtained by converting the picture format. The image format converter is used to convert many formats of pictures to each other, which is convenient to use. 

Summary of advantages and disadvantages of commonly used image formats:

① PNG Portable Network Graphics is the latest image file format accepted online. PNG can provide lossless compressed image files that are 30% smaller in length than GIF. It provides both 24-bit and 48-bit true color image support and many other technical support. Since PNG is so new, not all programs can use it to store image files, but Photoshop can process PNG image files and can also store them in the PNG image file format. 

② JPG or JPEG is the most commonly used image file format. It is formulated by a software development association. It is a lossy compression format that can compress images in a small storage space. Repeated or unimportant data in the image will be deleted. loss, so it is easy to cause damage to the image data. The JPEG format mainly compresses high-frequency information, and retains the color information better. It is suitable for photography and the Internet, which can reduce the transmission time of images and can support 24bit true color. 

③ The data of the GIF file is a continuous tone lossy compression format based on the LZW algorithm. Its compression rate is generally around 50%, and it does not belong to any application. Almost all relevant software supports it, and there are tons of software in the public domain that use GIF image files. Another feature of the GIF format is that it can store multiple color images in a GIF file, that is, dynamic pictures, which are now mostly used in network emoticons. 

④ ICO is one of the icon file formats of Windows, which can store icon files with a single pattern, multiple sizes, and multiple color palettes. 

⑤ BMP bitmap is a hardware-independent image file format, which is widely used. It uses a bitmap storage format and does not use any other compression except for the optional image depth, so the BMP file takes up a lot of space. The image depth of BMP files can be selected as lbit, 4bit, 8bit and 24bit. When a BMP file stores data, the images are scanned from left to right and bottom to top. 

⑥ WebP is a picture file format that provides both lossy and lossless compression, derived from the image encoding format VP8. WebP is a new imaging technology introduced by Google. It can effectively compress web page images without affecting the compatibility and actual resolution of image formats, thereby speeding up the overall web page download speed.

⑦ SVG scalable vector graphics is based on XML, developed by the World Wide Web Consortium. An open standard vector graphics language, the graphics can be enlarged arbitrarily, the edges are very clear, the text remains editable and searchable in the SVG image, there is no font limit, the generated files are small, and the download is fast, which is very suitable for For designing high-resolution web graphics pages.
