A PLP file in logo design is a project file format associated with software tools like CorelDRAW or other vector-based design programs. It stands for “Project Layer Package”, containing multiple design layers, objects, and settings needed for the development of a logo. These layers can include vector shapes, text, color palettes, and various graphic elements.

Designers often use PLP files to manage complex logo projects, allowing them to work with editable components in a non-destructive way. This format preserves individual layers so adjustments can be made later without losing quality, a key advantage when working with logos that may need resizing, recoloring, or modification.

Using a PLP file ensures that a logo design remains scalable and adaptable, making it suitable for different mediums like print, web, or merchandise. Once finalized, the logo can be exported in formats such as PNG, SVG, or PDF for different purposes.
