In the 2.0 version, SwifDoo PDF incorporates a new feature – OCR (Optical Character Recognition) to assist users in managing digital documents. This widespread technology identifies the unsearchable content and extracts the text in image-only PDFs.
It is an essential technology for both personal users and businesses to process scanned PDF documents. This type of PDF is not searchable, and the content within cannot be edited or changed. It only has scanned images of pages without an underlying text layer. The only way to make it editable is to perform OCR technology on the PDF. Mainstream PDF software has put it into operation, such as Adobe Acrobat, Foxit PDF, and Nitro PDF.

SwifDoo PDF offers four options to recognize and identify the text:
To maintain all the images and text that the original PDF has (recommended);
To keep and reproduce the original formatting as much as possible;
To convert the current unsearchable image-only document into a searchable but uneditable PDF document with images that can be copied;
To turn the PDF into a pure text document.
Users can specify the page range to recognize the text: all pages, current page, custom page range. To improve the accuracy of OCR, users can choose the document language. Based on the OCR from Abbyy, SwifDoo PDF now can read nine different languages, including Chinese (simplified and traditional), German, Spanish, Japanese, Korean, English, Russian and French. Tick the corresponding language to ensure high accuracy if your PDF documents are written in the mentioned language.
