The core of a web page is a file written in Hypertext Markup Language (HTML). Typically, the HTML file includes associations with other files that either appear on the web page or govern how it looks or works.
When you convert a web page to PDF, the HTML file and all associated files—such as JPEG images, Adobe Flash files, cascading style sheets, text files, image maps, and forms—are included in the conversion process.
The resulting PDF behaves much like the original web page. For example, the graphics, links, image maps, and most media files appear and function normally within the PDF. (Animated GIF files appear as still images, showing the last frame of the animation.)
Also, the PDF functions like any other PDF. For example, you can navigate through the file by scrolling or using bookmarks; users can add comments to it; you can add security, form fields, and other features that enhance it.
How much do you want to convert?
If you want to convert only a selected area of the currently open web page, use PDFMaker from within Internet Explorer. If you want to convert several levels or all of a multipage web site to PDF, work within Acrobat.
Do you want to create a new PDF from the web pages or to append the converted pages to an existing PDF?
You can do this in either Acrobat or Internet Explorer PDFMaker, but you choose different buttons or commands to accomplish these things.
Do you need to apply advanced conversion settings to the process?
The conversion settings available from within Internet Explorer are limited. Use Acrobat for the conversion process if you need to select additional settings. When you finish your selections and have converted at least one web page to PDF from within Acrobat, those settings will apply when you convert web pages from within Internet Explorer, too.
