Ubuntu converts the image format below the command line

Although you can use gimp to convert the drawing format, the operation is still troublesome. An easy way is to use the ImageMagick software. After the installation is complete, you can use the convert command. The convert command is very simple, for example:

Convert filename.jpg filename.bmp

You can use the-quality parameter to format JPEG and other images related to image quality. The value of the parameter is between 0 and 100. The larger the value, the larger the file. Usually, 60-80 can be used. For example:

Convert-Quality80Filename.bmp filename.jpg
