Dynamsoft OCR Engine

An optical character recognition engine which converts scanned images or PDF files into text

Dynamsoft's OCR Basic Module

Dynamsoft OCR is a fast and robust Optical Character Recognition SDK (OCR SDK) built on top of the Tesseract engine. It can OCR documents in different languages and convert any image-based text to searchable or edit-able PDF/text content.

Note: If you are looking for an OCR solution with more language support, better accuracy and faster speed, please take a look at Dynamsoft's OCR Professional.

Dynamsoft OCR can be embedded into web and .NET applications. Developers can either use the OCR engine standalone or as a plug-in for integration into a larger, custom image acquisition and recognition systems. Following are several samples which showcase possible usage scenarios.
