Photoshop files are often large documents with several layers of graphics and text. They can be difficult to email or save to a disk because of their size. One way to greatly reduce the size of a Photoshop file, yet still retain the look of the document, is to compress it to a PDF, which stands for Portable Document Format. PDF files are ideal for sharing on the Internet because they can often be password protected. You can convert your Photoshop document to a PDF, and while you're at it, also assign specific settings for compression, output and security.
