Scanned documents or photos of documents are not suitable for automatic text searches. This is why OCR software such as FreeOCRThe program scans the image files, recognizes the text they contain, and saves it with ASCII or Unicode characters in a text file or as a searchable PDF. OCR stands for “Optical Character Recognition” and describes the digitization of texts from graphic templates such as images.
Scanned documents, PDF files and images are the sources for FreeOCR. The freeware uses pattern recognition during scanning to recognize and digitize the contained text so that it can be further processed with any editor. For scanning, individual passages can be selected and digitized in sections, for example to ignore unwanted elements of a page.
Quality of OCR recognition
FreeOCR works internally with the OCR engine Tesseract, which Google has released under an open source license. Tesseract supports a variety of languages and writing systems, including many East Asian and Fraktur typefaces. If a language package is not yet available at FreeOCR, it can be easily installed from the Tesseract page, the manufacturer provides instructions on his website.
Supports different formats for image files
In addition to the common image formats BMP, JPEG, GIF and PNG, FreeOCR for Microsoft Windows also reads multi-page PDF and TIFF documents or scans directly from TWAIN-enabled devices. Recognized text can then be edited directly in FreeOCR, copied to the clipboard or exported to TXT, DOC and RTF formats, and further processed in programs such as Microsoft Word. During digitization, the OCR software only takes the text into account, but no formatting.
Other free freeware alternatives from OCR Software are SimpleOCR or gocr, the latter of which does not have a graphical user interface. ABBYY FineReader is a paid alternative that can handle text as well as formatting.
