This  should everyone know about Adobe Acrobat PDF reader:

• Adding online pages to an existing PDF instead of having to monitor and organise many documents is an advantage of creating  PDF Files from Almost Anything. Furthermore, rather than fiddling with the settings, reprinting, and hoping for better results, I could correct errors by rearranging photos and modifying the text directly.
• Documents always have the same appearance.
• Documents may be distributed for absolutely no cost around the world and then printed digitally.
• Documents may be enlarged up to 1600 times without sacrificing quality.
• Keyword searches, table of contents, and hyperlinks can all be used to navigate the documents.
• Because PDF documents look the same across all systems, the format is perfect for presentations.
• Because the file format is so small, files can be transferred to recipients fast.
• Ideal for preservation since the look and feel of papers are preserved while the document size is kept small.
• The file format is required for business documents such as agreements and forms that must be correct in appearance for legal purposes.
