Why does DEVONthink import PDFs only as images?
DEVONthink cannot extract the text part of print- or editing-protected PDFs. When you import them, you get a log entry that tells you that the PDF file contains “no text.” When you select these documents in DEVONthink, the status bar shows “image” instead of “PDF+text.” A cheap solution for this problem is Michele Balistreri’s PDFKey. This utility allows you to print protected PDFs. So, you can use PDFKey to “print” a PDF file into a new PDF that is both printable and editable — and the latter allows DEVONthink to extract the text for searching and classifying.
