The Free Online OCR Converter is an artificial intelligence-based tool used to convert images and PDFs into editable text. It has the capability to extract text from a variety of sources, including scanned documents, low-resolution photos and even complex mathematical expressions.

The tool's objectivity is achieved through its core recognition program, which utilizes advanced OCR technology and is powered by two of the leading machine-learning libraries: TensorFlow and Scikit-learn.

This allows for fine-grained data extraction from images and documents at a microscopic level. The user interface is simple and caters to a smooth user experience allowing users to simply drag and drop or upload their files for conversion.

The resulting text can be then copied or downloaded as a 'docx' or '.txt' file. Despite the advanced functionality, the tool is completely free to use and assures maximum accuracy in converting images or documents into text, supporting multiple languages.
