FREE OCR software: a survey of desktop and online tools


Printing text to paper is done every day; on some occasions however the reverse is needed – getting the original text back from a scanned image or photograph, for further editing and use.

This conversion is named Optical Character Recognition or OCR for short, and it can convert scanned books and documents into editable text, to get editable text from PDFs created via scanning, or even get text from screenshots and images. There are a variety of tools available for character recognition and some of them are free to use. This article will help you find and choose between several free OCR tools.

Note: this article was last updated on June 18th, 2013. This update added a host of additional tools that offer free OCR functionality, many of these we found through reader comments, so thank you for helping us make this article better.

Online OCR services vs. desktop OCR software

Selecting the right OCR tool depends on your specific needs. Generally OCR tools can be divided into two – online services and desktop software, both of them have their positive and negative sides.

Online services will require that you upload your files on the internet to their servers, so there may be privacy concerns as well as time/bandwidth concerns if your document is big. Most have limits to file size and count of pages to process daily/weekly that they will process for free; for bigger jobs they require to buy extra processing power. On the flip side, many of these services are really good at the OCR itself.

With Desktop Software you don’t need to worry about uploading sensitive information to foreign servers, or whether your file will take too long to upload. Some desktop software programs generally give better text review options, and some have scanning functionality integrated.

A note on comparing OCR software: OCR programs are not mainstream applications so there is only a limited number of freeware titles available, unlike for example hundreds of media players or file managers. In this article we aimed to provide the complete list of items found and evaluated at the present moment. This is because OCR results tend to vary; the accuracy of different OCR solutions depends on the quality, file format and fonts used in the source documents. For instance some programs provide better quality with typewriter fonts and worse results with screen fonts whereas other program perform exactly the opposite.

We therefore shied away from a head-to-head comparison of OCR accuracy in this article as the rating can be unjust for the specific files you might need to process. There is some general information about getting good OCR result at the end of the article.

We looked sat three ‘types’ of OCR tools: online OCR services, desktop OCR programs and other software (mostly screenshot taking programs that have an OCR component). All of the tools mentioned are either FREE or have a free version.


Quick links: click to jump to our  recommendation for online OCR services and recommendation for desktop OCR software. Also, see our recommendations for better OCR results.

Part 1: Online OCR software

Online OCR software is available through the web browser and you don’t have to install new software on your computer. All you need is to get the image file using scanner or a digital photo camera, upload it through the online OCR web page and wait for the processed file to download. Although most of the online OCR providers claim that data will be automatically deleted from their servers still the files travel through internet so for sensitive information you may consider desktop software from Part 2 or Part 3.


1. Google Docs

If you use Gmail or other Google online services you might try Google Docs/Google Drive first. Google Docs is not a dedicated OCR tool but it provides the OCR power Google uses to digitize books and process PDFs for their search engine. To get text from image or PDF files you need to first upload and convert the files to Google Docs. Then you can do the further editing online or/and download it back as PDF, DOC, TXT etc.

Click the Upload button first thing to upload your files, then select Settings from the menu and check ‘Convert uploaded files to Google docs format’ and ‘Convert text from uploaded PDF and images files’, then click Upload/Files. Another way is to check ‘Confirm settings before each upload’ after clicking Upload/Settings so that every time you upload a file you are asked whether you want to convert the file or leave it intact. This gives also an option to select which language dictionary will be used in the text recognition process. The file is therefore converted to Google Docs document having both the original image(s) and the converted text within it. You can review the text and delete the original images afterwards. Google Docs conversion works pretty good, especially with English texts.

Over 30 different languages can be selected but if your language is not included in the list, the conversion may give an error and the file will not be processed at all. Of course – if you don’t have a Google account you can create one any time. However, there are some limitations – the maximum size for images (.jpg, .gif, .png) and PDF files (.pdf) is 2 MB. For PDF files, they only look at the first 10 pages when searching for text to extract.


  • Input image file types: most bitmap formats

About OCR and how to get better results

OCR is used to turn printed books and documents back to text. OCR tools analyze the image, recognizes the characters/words and output them in form of editable text file. The character recognition is never perfect. By some studies the accuracy of the commercial OCR products vary from 70 – 98% and total accuracy can be achieved only with the help of human review.

To improve accuracy most OCR tools also use dictionaries. Instead of recognizing individual characters they try to recognize whole words that exist in the selected dictionary. Some OCR software cannot detect fonts and formatting and can only give plain text as output. You then need to reapply all the formatting manually. But some of the OCR engines detect fonts like bold and italic, some of them also detect paragraph formatting, multiple columns, tables and images inside the text, so they can use this information to replicate the text in editable format like DOC, HTML etc.

The source for character recognition can be an image obtained by scanner, digital camera or screenshot. If you use a scanner and you have lot of pages you might use OCR software that has scanner support built in. The program then suggests the settings that give best results for OCR. Usually this means 300 dpi resolution (200 dpi minimal) and gray-scale JPG or TIFF image. Some software like color images better than gray-scale, though. So if you do not get best results it is recommended to try several settings, like 300 dpi color JPEG and 300 dpi gray-scale JPG. Or TIFF instead of JPG.

Getting decent OCR results using images taken by digital camera is quite difficult. Good light, no flash, straight paper, macro mode etc help to get better results as it is described for instance in this article. It is also possible to get text from screenshot files but it also needs some extra measures. Usually the resolution of a screenshot is 72 dpi but OCR needs at least 200 dpi. Some OCR programs can automatically adjust the resolution of the image file, but for others you need to use some image manipulation program to convert the resolution to at least 200 dpi. For screenshots it is best to have dedicated screen capture programs that have built-in OCR functionality like ABBYY Screenshot Reader, Capture2Text or JOCR.

OCR is often used to process PDF files. A PDF usually consists of images that are shown on screen and also the source text that you can select for copy-paste. But some of the PDFs contain only images, like scanned PDF files. Usual “convert-PDF-to-Word” type software often cannot process these files. To extract text from PDF files that contain only images you need a viewer that can do OCR like PDF-XChange or some OCR software that accepts PDF files for input.

  • Te falto evernote…

  • ermete

    Sorry : could you tell me where you downloaded Cuneiform OpenOCR .
    If I follow the links of download it goes to a Russian page if, in that page, I click english version
    it goes to another page where you can dowload a demo.
    I did something wrong or is a treasure search game?

  • @Raul
    Espanol: Evernote no exporta a un archivo. Solo en la red.
    English: Evernote didn’t export its the text it recognizes or I would have switched over to it some time ago. Please someone post if this has changed.

    This is definitely a topic that needed review — thanks for covering it.

    Additional note: gImageReader *appears* to use a more recent version of the Tesseract engine than FreeOCR. Its also open source (GPL) and doesn’t require dotNET.

    Thanks rodocop

  • Doug

    I know it’s not freeware, but I’ve really grown to like the Abbyy line of PDF tools. If you get on their mailing list, they do have occasional good sales. The OCR capability is overall very good. Lite versions of their software is sometimes bundled with hardware scanners.

  • Hamstermoon

    I use It seems to allow more uploads (10 images an hour) than the others you mention.

  • Ron

    Although it isn’t free, another common tool is OneNote in Office 2007 and 2010. It incorporates OCR. Paste an image into OneNote, right click, and select the “Extract Text” option. It only captures text, not formatting.

    OneNote replaces MODI as OCR tool although there are techniques for getting downloading MODI into 2007 or 2010.

    On HowToGeek site, referring to this page, there is a comment about 2007 / 2010 Word providing OCR. I would really like to hear more about that. I, and several other “experts” I’m in contact have never mentioned OCR in Word.

  • Kent Dyer

    Here is a desktop app that does pretty simple captures of dialogs, Windows Explorer, etc. You do have to have Office 2007 (Imaging compents) or earlier installed to have it OCR, however. You have run it as a standalone (there is no install available) and it captures screens, sections too.

    I have used this for probably 3-5 years now and I make sure it is part of my toolset.



  • Hi,

    Thanx for the info. I tried CuneiForm for a Dutch text and it worked like a charm. I will test your other recommendations later on.

  • is a free online ocr software.

  • Hi, while it is not free, Abbyy Screenshot Reader is only about $10, it works superbly. I use it even on google books and frequently, also PDFs without an easy copy facility. (All done for fair use extracts, without having to type in many paragraphs.) The quality of the OCR of course varies with strange fonts, small text, etc … but for normal text it is superb, since Abbyy knows their stuff and has lots of more sophisticated products for other purposes (which I have not needed at all). About 3 years ago I bought it and it has been the best $10 purchase, by far.


  • PDF-XChange — a PDF viewer and basic editor FWG highlighted back in ’07 — just added OCR capabilities to the freeware and portable versions. I’ve so far been very impressed by the accuracy.

  • sheraz

    This is really an informative article, I came across a nice Jave OCR component. I hope you guys are going to like it. Here are some details
    Aspose.OCR for Java is a character recognition component that allows developers to add OCR functionality in their Java web applications, web services and Windows applications. It provides a simple set of classes for controlling character recognition tasks. It helps developers to work with image files from within their Java applications. It allows developers to extract text from images, Read font, style information quickly, saving time & effort involved in developing an OCR solution from scratch.

  • Leoncio Tritón

    Ni que hablar que Cuneiform me parece un excelente programa entre los programas OCR ya que dieron el link de descarga sólo agregar que la pagina a escanear se puede hacer con un archivo jpg de una camara a 2 ó 3 para dos páginas al mismo tiempo y tenemos que usar el treshold de algún programa de retoque como fotografix para contrastar la imágen, hasta obtener una imágen con caracteres legibles.

    Try Wondershare PDF Converter Pro (for Windows or Mac):

  • thanks,
    check out thisinterclue click less know more

  • Dave

    GT Text is very good one!
    At least free, fast and accurate

  • Richard

    Google Docs will only accept uploads of up to 2MB

  • Aware

    Really helpful. Thanks.

  • Francis

    Can any of these softwares also do Quality Check, i.e. once after conversion, they identify the (likely) errors in the converted text document?

  • Roger

    If you are looking for something free and decent try MeOCR Image to Text Converter it gives you formatted output that can be edited easily. The other ones just give you the text but its not formatted it makes me waste a lot of time reformatting also its pretty simple to use. Anyway that’s my 2 cents worth hope it helps.

  • ainpoenya

    Very nice list, just wanna add gettext is also free it can recognice from image in pdf extension very useful if you wanna get text from infographic or etc. bye.

  • lainIwakura

    free OCR is as efficient as abby fine reader ?

    • Frank D

      I can verify that ABBYY Fine Reader is much superior to any of the free Windows desktop OCR programs mentioned above. A simple screenshot of a typical webpage will illustrate this point. ABBYY will be virtually 99% correct, while the others are only 50% to 75%. In addition I have found that
      Aiseesoft PDF to Word Converter (~$35USD) is also virtually 99% correct and preserves most on-screen formatting.

      • Frank D

        Add this to the list of excellent PDF OCR readers: ABBYY PDF Transformer.

  • lane

    OCR results can improve a lot by preprocessing the scanned images. Try . A good resource on turning physical books into searchable digital text:

  • masskonfuzion

    Thanks for this post! Super helpful information. Just so you know, I used to use FreeOCR (desktop software), but its latest release (as of today, I’m referring to v5) comes with adware that previous versions did not have.. Based on the reviews on this page, I just switched to gImageReader + Tesseract, and it works pretty well for me.

  • ????????? ???????

    Hello, I’d like to advise

  • May

    Thanks for your suggestion. They are great. I heard of them before, but I did not use it. I am using Yunmai Document Recognition, a document reader developed by Yunmai Technology. It is able to extract the text from an image of a document, and then save it as text file. This software is a demo of Yunmai Document Recognition OCR SDK. The average time for recognition of a document less than 6 seconds. The recognition accuracy can reach 99%. It can convert documents into PDF, Word, Text format files.

  • ???

    Thank you very much. They are helpful for me. Simple OCR looks cool because it can recognize handwriting. When choosing OCR software, I always think about the recognition accuracy and recognition speed. As I know, Yunmai Technology is also very professional on OCR technology. Yunmai Document Recognition is really great for me. The average time for recognition of a document less than 6 seconds. The recognition accuracy can reach 99%. It can convert documents into PDF, Word, Text format files.
