FreeOCR is intended to recognize text from images. The tool has an easy-to-use interface; moreover, you can get help from online documentation. Fortunately, it supports importing images from various sources. Thus, besides using a scanner, you can also capture snapshots from a webcam as well as open images and PDF documents.
After opening an image, it is possible to rotate its contents to the desired position. To increase the accuracy of the recognition process, you can set an OCR language. Once the processing is finished, the program allows you to make some corrections that consist mainly on replacing generally misinterpreted combinations of characters.
While OCR is being performed, the resulting text is shown on the application’s left panel, which allows making manual corrections as well. This text can then be sent directly to Word, saved in RTF format or copied to the clipboard. Likewise, you can save the images in JPG format. Sadly, it cannot embed the recognized text in a PDF document, which is, in my opinion, the most desirable option.
All in all, FreeOCR is definitely a solution when you need to recognize text at no cost. The tool was tested with images obtained from a webcam and a scanned PDF document. Logically, the results were much better with the latter.
