A vector logo is a logo created in vector-based design programs such as Adobe Illustrator or CorelDRAW.
These types of logos are based on mathematical drawings (points, lines, curves, shapes), not pixels.
Features:
No quality loss: Can be scaled up or down infinitely (e.g., reduced for a business card, enlarged for a billboard).
File formats typically include:
.ai (Adobe Illustrator)
.cdr (CorelDRAW)
.eps
.pdf (if saved as vector)
.svg
Suitable for professional printing.
Colors can be separated, meaning they can be prepared clearly with CMYK values for print.
In summary: A vector logo = resolution-independent, always sharp at any size, and the correct logo format for professional use.
