After the acquisition of Macromedia by Adobe, the company decided to stop developing the old Freehand software, which was a vector design program, and instead add its features to Illustrator software; Adobe Illustrator is one of the oldest and best vector design and editing software and may not be comparable to any other software except the powerful CorelDRAW program. Using Illustrator, you can design and edit a variety of designs and shapes, logos, logos, boxes, etc. as vectors. Ai is a proprietary format for this software that can be imported and edited by various software.
