Free OCR - Extract Text from Images

Image to Text
Hi Dudes

We have seen the art of making Images using just ASCII characters: ASCII Art. Here I come up with a fantastic website that lets you to extract text from almost any images that contain some text. This will be useful to you in most of the situations where you should get or extract the text contents on images, photos or banners.

Optical Character Recognition
If you think of the concept of extracting text from an image, it would be some form of recognizing letters on the image using optical pattern reading. That is what called Optical Character Recognition (OCR). Certainly there should be a need of a device or machine that recognize the text. Okay! Now forget about whatever you thought of extracting text from images. There is an easy online solution to work for you.
Free OCR
This is a website with a free service of extracting text from your images. Whatever the image is, if it has something to read, this site will catch them for you. This is a free service offered, no need to register. Free OCR accepts either a JPG, GIF, TIFF, BMP or PDF. Here is a question that why do we need to extract text from a PDF file, while we have options to select and copy the text using Text tool. In case, you don't have PDF reader installed on your computer or your PDF file itself has some images in it! this will help you out. For PDF files, this service will extract text from the first page only.

Features and Restrictions
Free-OCR can handle images with multi-column text and also supports more languages: Bulgarian, Catalan, Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hungarian, Indonesian, Italian, Latvian, Lithuanian, Norwegian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovene, Spanish, Swedish, Tagalog, Turkish, Ukrainian, Vietnamese.

The only restriction is that the images must not be larger than 2MB, no wider or higher than 5000 pixels and there is a limit of 10 image uploads per hour.

Now, let's give a try with the site. This is the link to the site - .http://www.free-ocr.com/. I am going to upload an image containing some text, let's see the result. For instance, I take a screen shot of one of my posts on www.mysearchhistory.co.cc and upload to the Free-OCR. The uploaded image would be:

This is page where I upload the file, select English language, type the Captcha and click on 'Send File'.
