PSD is the native image format of Adobe Photoshop, supporting multiple layers, transparency, layer styles, masks, and smart objects. It is widely used in image editing, design, and digital art creation. PSD allows users to save each layer with its independent editing history and effects, making it ideal for complex image design tasks. Compared to traditional flat image formats like JPEG or PNG, PSD offers greater flexibility and editability, ensuring precise adjustments at different stages. It is widely used in professional design fields, suitable for advertising design, web design, UI/UX design, and various types of projects.

Additionally, PSD files often include metadata (such as author information, copyright information, etc.), facilitating management and search. Recommended editors include Adobe Photoshop and GIMP, which provide powerful image processing tools and full support for PSD files.

It supports transparency and can use lossless or lossy compression for optimization. In addition to Windows, ICO files are commonly used as favicons for websites. Recommended editors include IcoFX and GIMP, while ImageMagick can be used for format conversion.
