1. Open the PDF file in Adobe Acrobat Professional 11.0 (for large files this will take some time). - Pull down the Edit menu and select Preferences. - Under Categories, click on Convert From PDF. - Under Converting from PDF, click on TIFF. - Click on the Edit Settings button. - Under File Settings, pull down Monochrome and select LZW. - Under File Settings, pull down Grayscale and select LZW. - Under File Settings, pull down Color and select LZW. - Press Okay to close out the “Save As TIFF Settings” dialog box. - Press Okay to close out the “Preferences” dialog box. - Pull down the File menu and select Save As. - Type in a desired file name (the PDF file name will already be entered by default. If this is not desired then follow appropriate THL file naming conventions). - In the “Save as type” drop box, select: TIFF (*.tif,*.tiff). - Chose an appropriate folder in which to save all the extracted TIFF files. - Press Save.

Adobe Acrobat will spend a few minutes saving every page of the document as a TIFF file in the chosen folder. It will further order them correctly by adding a basic numbering convention to the end of the file name provided; i.e., filename_Page_001. For a 600-page PDF file, it should take 5-7 minutes for the individual images to be extracted.
