Optical Character Recognition (OCR)

Edit scanned documents on your Mac or mobile device! Take advantage of the power of OCR (Optical Character Recognition) in PDFpen for Mac and PDFpen Scan+ on your iPad or iPhone.

OCR (Optical Character Recognition) is the process of converting a bitmap image of text (like a scanned document) into text that can be selected, copied and searched by PDFpen and other text editing software. PDFpen for Mac uses the OmniPage OCR engine, which is recognized for its accuracy.

For more info, see Optical Character Recognition (OCR) in Wikipedia.

"If you’re looking for a way to convert already-scanned documents to usable text without rescanning, PDFpen’s OCR software may be a viable alternative to costly standalone OCR packages." - Macworld, 4 mice

Using OCR in PDFpen

ocr screenshot 1. Open a scanned PDF in PDFpen, or scan your document using PDFpen's "Import from Scanner" command.

2. An alert box opens with the message “This document appears to be scanned. Would you like to perform optical character recognition (OCR) on it? OCR will allow you to select the text.”

3. Click on “OCR Page” or “OCR Document” to start the OCR.

Once OCR is complete, the text generated by the OCR operation can be searched and edited like any other text.

Tips to Improve the OCR Results of Your Document

The quality of the original document affects the quality of the OCR performance. Crisp, clean originals with clear text will produce much better results than crumpled, faded photocopies.

Before performing OCR, use PDFpen's "Deskew and Adjust Image" command to straighten the image and to adjust image contrast and exposure for optimal OCR results.

Documents in a standard paper size, like US letter, work best. Documents with large pages, like architectural plans, do not OCR very well.

OCR technology does not always produce perfect results. You do need to proofread and edit the text that results from OCR

  2. In that page, tap “OCR”. You will have to option to copy any recognizable text of that page, or of the whole document. To copy text from the whole document you will need to have run OCR on the whole document.

Once you have run OCR, you will see a blue overlay of the OCR results. Tap the document to make the preview appear or disappear. Youcan also acces the preview through the "OCR" menu.

Tips for Good OCR Results

A good clean scan will get the best OCR results. To take a good scan, make sure the document is well lit. Use the grid lines included in the camera view to keep the document as straight as possible. Whether you have taken a new scan, or have opened a PDF, if it is dull or dim go to the edit screens and increase the contrast and brightness of your scanned document so that the text is as legible as possible.
