Embodiments of the present invention provide a system for image capture and conversion. The system receives or captures an image of a resource document comprising image coordinates. The system can then cause a user interface of a computing device to display the image of the resource document and request that a specialist provide an input of an image coordinate area associated with a data field of the resource document. The specialist then provides a selection of boundaries for the coordinate area that encloses a value of the data field within the image of the resource document. The system then applies a data field-specific OCR process to the provided image coordinate area to extract a value of the data field. The extracted value can be presented on the display along with an enlarged view of the image coordinate area to allow the specialist to verify the accuracy of the extracted value.
