ocr softwareBelieve it or not, some people still print documents to physical pieces of paper. Optical Character Recognition (OCR) software takes those printed documents and converts them right back into machine-readable text. We’ve found some of the best free OCR tools and compared them for you here.

No OCR program is perfect, so you’ll have to double check the results and fix a few problems. Still, it’s a lot faster than typing the entire document back into the computer. Each of these free OCR software tools has its own strengths, and all of them will get the job done.

The Methodology

To compare these tools, I printed out MakeUseOf’s About page and scanned it back into the computer. With multiple columns and imperfections, this is not an ideal document to OCR. But that’s a good thing – real-life OCR operations will often be with imperfect documents.

Google Docs

Google Docs has integrated OCR support. It uses the same OCR engine that Google uses to scan books and understand text in PDF files.

To get started, open the Google Docs website and start uploading a file.

Enable the “Convert text from PDF and image files to Google documents” check box when you upload the file.

After you upload the file, it will appear as a new text document in Google Docs.

Google Docs did a pretty good job here. It struggled to understand the web addresses, but all these tools did.

Unlike many free online OCR tools 3 Online OCR Services To Convert Scanned Docs To Text 3 Online OCR Services To Convert Scanned Docs To Text Read More , like Free OCR Convert Images To Text Online With Free OCR Convert Images To Text Online With Free OCR Read More (which is different from the FreeOCR below), Google Docs doesn’t have any limits on the amount of pages you can upload.


Editor’s Note: users have reported malware bundled with recent versions of FreeOCR; we recommend you not download the software at this time. Links have been removed, article content remains for reference.

FreeOCR is a simple, easy-to-use frontend for the open-source Tesseract OCR engine, originally developed by HP Labs. FreeOCR comes bundled with Tesseract, so you don’t have to install anything extra.

Use the Scan button to scan a page directly from your scanner or use the Open option to open an image or PDF file.

Click the red X button to clear the pre-filled text before continuing. After opening the file, click the OCR button on the toolbar and FreeOCR will start crunching away.

FreeOCR gave good results on the main block of text, but it was confused by the columns. To fix this, I selected the block of text I wanted and used the “Crop image to selected area” option.

The results were much better after running the OCR operation on a specific section of the document.

Cuneiform OpenOCR

Cognitive Technologies developed Cuneiform as a commercial OCR solution, but eventually released it as freeware. Cuneiform OpenOCR has an unpolished interface, but there’s an excellent OCR engine underneath.

The download page is in Russian — scroll down and click the “english version” setup link to download and install Cuneiform.

After you install it, you’ll find that it didn’t create appropriate Start menu entries. The “NewShortcut6” shortcut will launch OpenOCR.

From the File menu, use the Open option to open a file or the Scan option to scan a document.

After it’s in OpenOCR, use the Recognize option in the Recognition menu to OCR the text. Cuneiform OpenOCR will save it as a file.

Cuneiform OpenOCR provided good text recognition. It also preserved the formatting and text size differences – unlike the other programs here.

The Verdict

Each of these programs has its strengths.

  • Google Docs can OCR documents without downloading anything to your computer.
  • FreeOCR offers a very easy-to-use interface, but requires some fiddling if a document contains columns.
  • Cuneiform OpenOCR preserves much of the original document’s formatting, but its interface lacks polish.

    This is very educational! Thank you! I have a low quality scanned PDF files and unfortunately, the free online converters did not work. I came across this software called PDF2XL Enterprise by Cogniview. I tried to convert few of my documents and I’m satisfied with the result. The software has advanced OCR settings you can adjust like tweaking and force dpi which totally improved the character recognition. I would definitely recommend PDF2XL Enterprise to anyone.

    it works only when the text of the image is in normal font that is "times new roman" but fails with other fonts.
    is there any software that recognises all the types of fonts

    Thank you Chris Hoffman for your helpful article.

    FreeOCR looks just what I'm looking for. Unfortunate to read your note that it has been reported to contain malware. Could you tell us if it is still the case? I see your article was written in 2012. Perhaps the note was a later update? Or could you share how I can find out for myself whether it is still contains malware? Thank you.

    My alternative would be to work with Tesseract, but that looks more complicated to install and I read that it is not the most user friendly.

    Drive instructions are beyond outdated. Here is how it is done these days.

    To open PDF in Drive:
    --Open Drive,
    -----Select Settings (gear icon far right-top),
    -------Select Settings again,
    ---------Click "Convert uploaded files to Gooogle Docs format".

    Now only imported files will open. PDF's that were already in Drive will need to be "Uploaded" from the Drive folder to the Drive folder. Basically, any files already there need to be selected and "Downloaded"
    This goes for all Office files as well as PDF's.

    The free OCR tools you suggest are great for me. 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 enables scanned documents and images to be transformed into searchable and editable document formats. 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.

    Hello Chris,

    Thanks you for sharing a great online tool in this post. Free tools have their own features, but that are negative points too. Free online converter store your PDF file on their sever (your pdf file could be have some personal information).

    Personally I would like to share a tool here i.e. "PDFWARE Image to PDF Converter". This software has many options to add Images in a PDF document. It convert all types of Images into pdf document. I will recommend it to other user.

    Hey bro - as a reviewer you should take the time to review the product EULA and data / security policies.
    These are at least as important as the features offered.

    I did not appreciate the spyware packaged with your recommendation (FreeOCR), or the agreement that would allow collection and use of personal data.

    You should have mentioned these negatives. No prize for this review.

    • Chris Hoffman
      June 21, 2012 at 11:16 pm

      Handwritten text is a much harder problem, as handwritten characters aren't as distinct as typed ones. It's difficult to find a program that will work well for this.

      You might try SoftWriting, which has a free trial:

      You might also try SimpleOCR, which seems to have this feature -- but it doesn't seem to work very well:

    Not sure whether Google Docs ever had this same limitation, but Google Drive (which it appears Google plans to eventually replace Google Docs with) limits its OCR'ing of any PDF you upload to just the first ten pages. The 2 MB file size limit also still applies, but this ten-page limit is even more restrictive.

    However it's good they still don't restrict the number of documents you upload. As a result, you can still OCR an arbitrarily large number of pages for free on Google Drive -- ten pages at a time.

    • Chris Hoffman
      June 10, 2012 at 8:38 am

      That's unfortunate. It's still a pretty great service, though -- hard to complain when it's free and happens on their servers.

      • mathematrucker
        June 10, 2012 at 4:20 pm

        I agree Chris. Also note, since the ten-page restriction applies only to PDF format there could be a simple workaround. There might be another multipage file format such as TIFF that a person could convert their PDF to before uploading.

    I use ocr a lot and have tried almost every free option out there. For straight forward text they handle just fine, but send through complex layouts and expect to spend hours editing. Recently I forked out for the premium Omnipage, and although I am now broke, I have to admit that the program makes everything else look inefficient. Simple pages are ocr-ed in seconds and are perfect. Complex layouts take a little longer because you need to define graphic, text and table areas, but the results are near perfect. I am not saying that the options mentioned here can't do the job, but if you have big projects in need of ocr, or ocr documents regularly, then save the headache and pay for the master!

    • Chris Hoffman
      March 26, 2012 at 9:40 pm

      Thanks for sharing your experience, Carie. I've never used Omnipage so I can't speak to it, but it may well be a good idea to pay for more powerful OCR software if you need it.

      Hi! I also use Sprint but, probably, for big projects with a lot of formatting and complex layout I need a full product that will save the original structure and convert pdf. Not sure what product to buy, do you know if I can upgrade from Sprint (and if it is cheaper) to complete version of finereader ?

      • Chris Hoffman

        I'm not sure what the best paid product to buy is either -- you might try asking on MakeUseOf Answers to get more feedback:

        I'm sure you can upgrade to the full version though -- since it's just a matter of paying for the full version and downloading it.

          The best two packages bar none for accuracy, layout preservation etc (not necessarily for speed or ease of use) are Abbyy FineReader Pro and Nuance OmniPage Professional. Personally, I prefer the Abbyy product which is much more elegant and flexible (allowing you, for example, to define specific character sets which can enhance the accuracy of the document). However, the Nuance product is also very good.
          Another big player is IRIS, whose products are are geared towards "productivity" rather than for accuracy. They are much faster, and most of the IRIS packages are largely "hands off" (no interactive layout recognition or spell checking, for example). This is suitable for those who are scanning into searchable PDFs, where absolute accuracy is not paramount, but speed is!

    • Chris Hoffman
      March 20, 2012 at 8:16 pm

      Thanks for sharing that, Danny!

      I'm sure all services have a max file size -- it's sad that Google Docs' file size is so low.

      However, you could always split the document into several files and upload them one by one -- Many free services say "x pages" or "x documents" as a limit; that's no fun.
