OCR or Optical character recognition is an useful technology to convert an image into a machine readable text. The image can be of a scanned document or a printed text. Though the OCR software are not new, there has been a tremendous improvement in their performance and accuracy.

Why OCR Software?

Now that you know what OCR technology is all about, you might be wondering why you actually need to use an OCR software. Well, if you happen to run a business of any size, you will agree how important it is to computerize your office documents and records and be eco-friendly. Moreover OCR lets you edit the text, search for a word or phrase, store it more compactly, display or print a copy free of scanning artifacts.


With the advancements in OCR technology, you don’t need to worry much about the fonts used in the scanned image for the conversion to happen. Most of the commonly used and popular fonts are supported these days. Some OCR software these days are smart enough to recognize and convert handwritten documents as well!

Free OCR Software

While I recommend Online OCR tools (discussed below), some of these free OCR software can be a boon when you don’t have access to the internet or if you need to convert a lot of images into text at once.

1. SimpleOCR

SimpleOCR is a popular free OCR software which is up to 99% accurate as claimed by the developer. With SimpleOCR, you easily and accurately convert that paper document into editable electronic text for use in any application like MS-Word. It comes with a built-in dictionary of more than 120,000 words and gets better with each use. It does a fair job of retaining the original format of the document and can also retain pictures wherever possible. And the best part about SimpleOCR is that you can batch-process several documents in one go!

2. FreeOCR

When compared to SimpleOCR, FreeOCR is much simpler and more straight-forward to use software. It is based on Tesseract OCR engine was developed at HP Labs between 1985 and 1995 and is currently with Google.FreeOCR supports scanning from most Twain scanners and can also open most scanned PDF’s and multipage Tiff images as well as popular image file formats. FreeOCR outputs plain text and can export directly to Microsoft Word format. It supports all versions of Windows including Windows 7, Vista & XP.

4. GOCR

GOCR is another popular OCR software, developed under the GNU Public License. GOCR can be used with different front-ends, which makes it very easy to port to different OSes and architectures like Linux & Mac. For Windows, there is a separate frontend and is pretty simple to use.

5. Microsoft OneNote or Microsoft Office Document Imaging

You might be surprised to know that either OneNote or Office Document Imaging can be used for OCR. In OneNote, just right click on the picture and select ‘Copy Text from Picture‘. The program will automagically captures the text into the clipboard which you can use to paste it in your document. Or else you can look for Microsoft Office Document Imaging under Microsoft Office Tools which can be used to convert TIFF/MDI files to text.

Free Online OCR

It is wiser to use an online OCR service when you have very few images to get converted to text. If you are someone who uses Google Docs often, you can simply check the option that says “Convert text to Google Docs format” and it will automatically perform OCR on the file before saving it. But Google docs come with many limitations like inability to retain document formating. For that, you can check these following alternatives.
