Documents can also be returned in Unicode Braille or formatted in either text format or PEF (Portable Embosser Format).

Furthermore, RoboBraille is capable of converting well-structured Word documents (doc, docx, xml) into Daisy Talking Books complete with audio. Similarly, RoboBraille can convert docx documents containing math (composed in MathType) into Daisy books with spoken math.

E-Book services: Most document types listed above may be converted into the popular EPUB and Mobi Pocket (Amazon Kindle) e-book formats. The service also supports conversion of documents into the EPUB3 format, including EPUB3 books with media overlay. Furthermore, EPUB may be converted to Mobi Pocket and vice versa. To accommodate users with low vision, the base line of the body text in an e-book may be raised to allow for more appropriate text scaling in mainstream e-book readers. Accessibility services: Otherwise inaccessible documents such as image files in gif, tiff, jpg, bmp, pcx, dcx, j2k, jp2, jpx, djv and image-only pdf, as well as all types of pdf files can be converted to more accessible formats including tagged pdf, doc, docx, Word xml, xls, xlsx, csv, text, rtf and html. Word and rtf files are converted into text or tagged pdf files subject to the format specified by the user in the subject line, e.g., txt or pdf. PowerPoint files are converted into tagged pdf, web projects or rtf files. In addition to the traditional email-interface, RoboBraille is available via the web form at http://www.robobraille.org/ History RoboBraille was invented in 2004 by Lars Ballieu Christensen, a computer scientist and social entrepreneur and Svend Thougaard, an alternate media specialist. The system was developed in Denmark with the assistance of the Royal National College for the Blind based in Hereford, United Kingdom. The system was launched in June 2006 and was the winner of a British Computer Society Social Contribution Project Award in 2007.
