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.

Due to the maintenance of our university's power facility, some WeOCR servers are due to be temporarily unavailable on Aug. 28, 2016. The services will resume soon after the maintenance work.

Dear developers,
You can help visually disabled people through WeOCR. See here:


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.




The license is the Apache License, Version 2.0.
(An MIT-X derivative applies to weocr-toolkit-0.12 and older.)

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