OCR With PDFpen

Summary: Uses optical character recognition to add a text layer in a scanned PDF.
Requires: EagleFiler, PDFpen or PDFpen Pro
Install Location: ~/Library/Scripts/Applications/EagleFiler/
Last Modified: 2020-06-03


This script uses PDFpen to perform optical character recognition on a scanned PDF file. This makes the contents of the PDF searchable in EagleFiler. Initially, the PDF has only an image layer; after running the script it has an image layer and an invisible text layer. If the PDF file had the “NeedsOCR” tag because you had used the Tag PDFs that Need OCR script, the tag will be removed after OCR has been applied.

There are several ways to use this script:
