Software Reviews – Top 5 Best Free OCR Software

Let’s say you want to edit and analyze information in a book using your computer. How would you do it? It sounds obvious to just scan the book. But a scanned document is just an image, and little can be done to edit the text in an image. Therefore, most people result in manually retyping the text. What this people do not know is that there is a technology called Optical Character Recognition (OCR). This technology analyzes printed text in images and converts it into data editable on a computer. That’s why we provide the info and download sources of the Best Free OCR Software in this post.

What is OCR & How OCR Works

When you are presented with a page of written text, like this one, it is only valuable to you if you can recognize the language and read it. The brain recognizes the character patterns (which are letters, numbers, and punctuation marks), and converts the characters to words, and words to sentences.

Computers too can recognize characters and convert them to text. First you have to present the computer with an image of the text, a scanned file or an image from a digital camera. An image is nothing but a pattern of pixels. In other words, an image of the text is no different from an image of the Eiffel Tower. So, OCR software helps the computer convert image of text into text itself. These software convert images of text into DOC file or TXT file. These formats can then be edited and manipulated using programs such as Microsoft Word.

The OCR process

OCR involves a process. Each step of the process is important in determining the accuracy of the final text.

  • Enhancing the print. The OCR process begins with the printed document o be converted. If it has marks, coffee stains, and poor contrast, the software is prone to make errors during character recognition. You can photocopy the print to enhance its quality.

  • Scan the print document. OCR software works with image files. Scan the document to convert it into an image. A good digital camera is a good option as it will produce sharp images of the documents.
  • Black and white (two-color). You have to convert the scanned files to black and white. The OCR process is binary (a character is there or not). The black color in an image is part of a pattern to be recognized and the white is the background.
  • Character recognition. The next stage is the optical character recognition. The speed of this process is dependent on the OCR program used. Most of these program analyze each character on the image one after another. The purpose of OCR programs is character recognition but good programs recognize images and tables, and other layout elements in the scanned documents.
  • Error correction. The process is not perfect as there are many factors that may affect the accuracy. OCR programs have inbuilt spell checkers, and will highlight any potentially misspelt word. Some of these programs have are so sophisticated they will highlight word mismatch and grammar errors.

Generally, that is how the OCR process works. Always proofread the final work, especially if the original document was of poor quality.

Best Free OCR Software Can Help You:

OCR software programs have many benefits to businesses, student, law professionals, medical professionals, and many other people. Here are the 5 main reasons you need an OCR software.

  1. Avoid retyping

    The alternative to OCR technology is manual typing. Retyping work that already exist is tiresome and a waste of precious time. With OCR you no longer need to retype anything that already exists.

  2. Edit printed text

    Once the OCR program has scanned and converted the image files to text, you can easily edit the text. You can add new information, and even add images to the original text.

  3. Perform quick digital searches

    The scanned documents can now be saved as word documents. In that format, you can easily perform a quick search based a keyword phrase. Secretaries no longer have to peruse through a mountain of files to locate an invoice.

  4. Free up space

    Paperwork, especially in a business setting, can really eat up physical space. Once you scan all the papers, and store them in doc. or PDF format, you no longer need files and file cabinets. You will, therefore, save a lot of office space.

  5. Quickly access information

    Saving documents in digital form not only saves office space, but also allows quick access of documents. Also, these files can be accessed remotely.

How we arrived at this list of best free OCR Software

We did not just randomly pick the best free OCR software. We tested and reviwed each of the software putting the following factors into consideration;


Accuracy is what differentiates a good OCR program from the bad ones. Nonetheless, it is unrealistic to expect 100% accuracy from any OCR software. Factors such as the quality of the original scanned documents, and quality of the scanner itself greatly influence the final result. Good OCR programs will always achieve a 98% when used with a good scanner and with the original documents in mint condition. Until you test the program, always take the accuracy claims of the manufacturer with a grain of salt.

Multilingual Support

Some OCR programs recognize more than one language. Such programs should be your choice if you will scan documents in another language. OCR software scan an individual character to determine what letter it is. Software programmed to only recognize English characters will not accurately interpret special characters such as β or accented letters such as é. Such software will represent these characters with the nearest equivalent in English.

When using a software that supports multiple languages, you have to specify the language of the document so that it can OCR accurately.

Handwriting support

Printed text (produced by a printer) is easily recognizable by any OCR program. However, handwritten text is a totally different ordeal. People have very different handwritings. Some write neatly, while most handwritings are not legible enough for humans, leave alone computers. Decent OCR programs, however, can recognize neatly hand written text. So, if you are going to be archiving handwritten documents, look for OCR programs that recognize handwriting.

Level of automation

OCR software can either run automatically or interactively. If you will need to scan many documents at a time, you should consider OCR programs that ran automatically. With such a program, in a few clicks you start scanning documents, go on with other tasks, and come back to find the editable PDF, txt, or doc file. Most free OCR software have limited automation. However, you will find out that interactive input offers the most accurate results.

Layout retention

The main purpose of these programs is to convert image text into text. Some will not retain the layout of the original document. Therefore, you will have to do a lot of editing on the final copy. A good program should retain the original layout, so that minor editing work is needed in the final copy. Some of the programs reviewed below will retain the columns, tables, and graphic images in the original document.
