One neat thing about PDF is its ability to represent content from disparate sources, such as images, formatted text content, spreadsheets and graphs -- and that's not even mentioning the multimedia or 3D options. In fact, it's a simple matter to combine a collection of PDFs or other files into a single, self-contained PDF.

When you compile a PDF from multiple sources, you might find that some of the pages are sideways or inverted when you try to view them on-screen. Never fear! Acrobat can be used to rotate individual pages within a PDF document.

Sometimes, you just want to convert a file into a PDF document -- fast. With Acrobat, the task can be as simple as right-clicking. While this doesn't work with all file types, it is perfect for use with text files, Excel spreadsheets, Word documents, HTML files, image files and various other file formats.

Sometimes, you need to change the page order of your PDF documents. Luckily, you don't need to re-recreate the file from scratch, as it's a simple matter to re-order pages in Acrobat. In fact, it's as easy as dragging-and-dropping.

PDF is a great format for document delivery. With a little know-how, it allows you to send compact documents with the confidence that they will be faithfully displayed on your recipients' systems. What you might not know is that Acrobat includes a 'PDF Optimization' feature that can reduce file sizes even further. It can be used to adjust image compression settings or remove potentially unnecessary document elements such as comments, bookmarks or links.

By default, Adobe Acrobat allows users to place various standard stamps on your documents such as 'Approved', 'Declined' or 'Accepted'. That said, you can also create your own custom stamps. Using this option, you can take a logo or other image from another application and turn it into a custom stamp. Once created, you can apply it to any PDF document in Acrobat.
