Update: The service has seen an overhaul of frontend and the OCR engine (tesseract)
From now on we deliver free online OCR under www.ocr-extract.com. Currently the service supports PDF, PNG, TIFF, JPEG, BMP, PBM as input file format. It extracts text from 35 languages.
The service may not be used for commercial purposes, either directly or indirectly, without prior permission from the server administrator(s).
We'd love to provide you with a proposal for an appliance or a hosted solution of the service.
