Photoshop and Illustrator are two widely used graphic design tools, but they have different focuses and functions.
Photoshop is primarily used for image editing and manipulation. It's ideal for retouching photos, creating visual effects, adjusting colors and textures, among other tasks related to image treatment. Photoshop offers a wide range of tools and filters for working with pixels, making it a powerful choice for photo editing.
On the other hand, Illustrator focuses on creating vector graphics, which are images based on mathematical vectors rather than pixels. This allows graphics created in Illustrator to be scalable without losing quality, making them ideal for logo designs, illustrations, typography, and works that require sharp lines and precise shapes. Illustrator also offers drawing tools, object manipulation, and advanced text options.
