What are Adobe Acrobat documents?

Adobe Acrobat (PDF) documents are just another MIME document type on the web, like movies, JPEG or GIF files. Traditionally these files have an extension of ".PDF". Many web browsers directly support the PDF format natively or through plug-ins, otherwise an external application, the Adobe Acrobat Reader, is required to view these documents. This plug-in or external helper application, which is available free from Adobe, allows a document to be viewed exactly as it was intended on all platforms. It may then also be printed or stored on your local system for later viewing.

What do I have to do to view Adobe Acrobat Documents?

To view and print PDF documents you must have a browser that supports the PDF format natively or through plug-ins (e.g. Netscape or Microsoft Internet Explorer) or you can use an external application, such as the Adobe Acrobat Reader or Adobe Acrobat Exchange. Both the plug-ins and Adobe Acrobat Reader are free from Adobe Systems. Complete instructions for installation are included with the software.

If your browser does not have native or plug-in support for the PDF MIME type, your web browser can either be configured to launch an external "helper application" or it will download the file for external viewing. Instructions for configuring popular web browsers are available from Adobe.

Free Adobe Acrobat Readers and PDF plug-ins are available for the Macintosh, Microsoft DOS, Microsoft Windows, and Sun Unix systems. For information about how to download the software and configure it, please read the instructions from Adobe's web site,

Can I save the PDF document to my hard disk?

Yes. Select the document with your web browser. If your browser is configured to recognize PDF files properly, it will display on your screen and you can save it in your browser. If not your browser does not support PDF files or is configured incorrectly, it will most likely ask if you want to download the document as a file on your system.

Do a lot of people publish documents on the Internet in Acrobat format? Why?

Yes. Many sites publish documents on the Internet using the Acrobat format since it allows the document to be distributed exactly the way it was designed. Any two people who view or print a PDF document will see exactly the same output. Different web browsers often produce different results, and can use different fonts and formating. For instance, the Internal Revenue Service uses Acrobat to make its tax forms available online. By using PDF format, they can be assured their forms will appear exactly the same as the printed ones.
