WeOCR Project

Since Feb. 2005 / Last update: Sep. 15, 2019

End of Services
Thank you very much for using the WeOCR services for more than twelve years. As we can see a lot of nice online OCR systems today, I have decided to close our services. The servers will be shutdown gradually, although some will remain working only for demonstration purposes.

When I started developing "Online OCR service" in 2004, there were only a couple of experimental ones, which had been almost abandoned. Who at that time imagined that online version of OCR service would be practical enough despite the privacy concerns? Who would provide free OCR services when the OCR engines costed much? We can see the consequences today. There's a high demand. Some high-performance OCR engines are available for free.

I don't know if the WeOCR project had some contributions and/or impacts in the world of web service developments. But, it is obvious the services here are no longer attractive. So, it's time.

Thanks again to everyone who tried our services and programs, developed his/her own service, got some inspirations (if existed) for new online services.

Don't use bots (automated programs) regularly. The server performance is limited, and people suffer from high loads! You should use a local OCR engine if you need a regular processing since it is much more reliable and faster basically.


WeOCR is a platform for Web-enabled OCR (Optical Character Reader/Recognition) systems that enables people to use character recognition over networks. A WeOCR server receives document images from users, recognize texts in the images, and return recognition results to the users. WeOCR does not have its own character recognition engine. Instead, it is intended to accommodate various character recognition engines. WeOCR provides a simplified user interface so that more people can benefit from OCR easily.

Although some people would worry about the privacy of their documents, we think there are still a lot of applications of OCR in which privacy does not matter. We hope WeOCR will expand the range of OCR applications further.



WeOCR-toolkit has the following features.

You don't need to open the source codes of your OCR engine to the public, if you wish so.
