Excuse me, it takes 2M for photography. Is this a size requirement or a pixel requirement? How to convert?

This is about the size of the work. 2M is the storage size of the picture, not the pixel or size!

There are many methods of conversion, such as photoshop, coreldraw and so on. Because using these professional tools will not distort the work.

Simple, start-program-attachment-drawing-pasting or opening-and then save as -JPEG format! His size has changed!
