ตัวแปลงไฟล์ออนไลน์ฟรี CGM เป็น VIPS

This is used to exchange vector graphics among different platforms. It stores not only 2D vector images, but also raster images. It allows you to store a large number of graphical information types and is applied primarily for design in aviation, engineering and other technical fields.

VIPS is a format used by libvips internally for calculation but it can also be used for storing images. It is simple, fast and has no size limit. However, only a few other programs are able to open such files which is why it is better to convert them to a more popular format.
