There are 9 formats for mobile phone pictures, including BMP, JPEG, JP2, GIF, TIFF, PNG, EXIF, WBMP, and MBM.

1. BMP: BMP is an image file format that is independent of hardware devices. It is also the standard bitmap format under Windows systems and is widely used.

2. One of the advantages of the JPEG format is that it can compress image data. JPEG is a lossy compression format that can compress images into a small storage space. Repeated or unimportant data in the image will be lost. is lost, thus easily causing damage to the image data.

3. As an upgraded version of JPEG, JPEG2000 has a compression rate about 30% higher than JPEG and supports both lossy and lossless compression.

4. GIF (Graphics Interchange Format), whose original meaning is "image interchange format", is an image file format developed by CompuServe in 1987. The data of the GIF file is a continuous tone lossless compression format based on the LZW algorithm.

5. TIFF (Tagged Information File Format) is a relatively common image file format developed by Aldus and Microsoft companies for desktop publishing systems. It was designed by Aldus Corporation in 1986 and is an innovative format. The distorted 24-bit color image format can maintain the colors and lines of the original image, but takes up a lot of space.

6. The full name of PNG is Portable Network Graphics format. It is a very new file format developed by Web Graphics Company. Currently the most distortion-free format is PNG.

7. The EXIF ??format is a digital camera image file format promoted by Fujifilm in 1994. It is actually the same as the JPEG format. The difference is that in addition to saving image data, it can also store the shooting date, aperture, shutter, Exposure data such as flash data and accompanying information as well as small size images.

8. Wireless Bitmap (WBMP) is a standard image format used by mobile computer devices. This format is used specifically in Wireless Application Protocol (WAP) web pages. WBMP supports 1-bit color, that is, WBMP images only contain black and white pixels, and cannot be made too large, so that they can be displayed correctly on WAP phones.

9. MBM format file is the bitmap file format of Symbian OS. This is a multi-bitmap file. The window bitmap uses a bitmap conversion tool bmconv to create the MBM.
