The PSD format is Adobe Photoshop’s native file format which can be used across both PCs and Macs. It supports advanced features like layers, alpha channels, paths, and vectors. PSD files are widely used for designing website layouts that can later be converted into fully functional web pages.

PSD files are highly customizable and allow designers to modify images, layouts, and elements easily. If additional fonts are used in the design, they are typically included along with the Photoshop file, making it convenient for further editing.

PSD (or sometimes PDD) is a widely accepted format that supports multiple image modes such as Bitmap, Grayscale, RGB, CMYK, Lab, and more.

One of the biggest advantages of PSD is its support for layers. This allows designers and developers to edit different parts of an image independently, making future updates and customization much easier compared to flattened image formats.
