Acrobat doesn't come with an Import and Export feature as its Creative Suite siblings do, but that doesn't mean you can't bring files in other formats into your PDF documents. Here's a list of file types Acrobat enables you to bring in:
Static graphics can't be directly imported into Acrobat; if you need to add graphics from your hard drive or a CD to an existing PDF, do it with Designer. Adobe Designer enables you to import image files in BMP, GIF, JPG, PNG, and TIF formats. You also can bring 3D CAD images in U3D format into Acrobat very easily.
Many popular formats are supported, including AVI, MOV, MPG, RM, SWF, and WMV.
Audio tracks are supported in AIF, MP3, MP4, RA, WAV, and a few other less-popular formats.
Besides creating PDF files Acrobat gives you the ability to save your PDF to some useful formats that include
JPEG, TIFF, and PNG graphics
If you need to rasterize images, create thumbnails of your PDF files, and/or create rough pictures for quick proofing, these three formats fill the tab. The TIFF format allows for lossless compression and the PNG format has the added ability to retain transparency, in case your document needs it. Saving as JPEG can be useful when doing quick comps where image quality is not a big issue.
HTML and XML
In some cases you need to have a document as both PDF and HTML (or XML) in a website. Saving your PDF as HTML or XML saves you the trouble of having to re-create it in GoLive. When saving as HTML or XML, Acrobat creates an Images folder in which to place all the images included in the document. Images are saved as JPEG.
PS and EPS
Use these formats for prepress and print production purposes.
DOC, RTF, and TXT
Use these formats when you need a text version of a document for editing or archival.
