Effortless Word to PDF & Image Conversion: Share Easily and Enjoy Accurate Displays. Directly Convert Files on Servers, Backend, Command-line. No Additional Software Required.
Office Server Document Converter (OSDC) is a server-side conversion library for Microsoft Word, Excel, PowerPoint and RTF documents to PDF, SVG, TIFF, JPEG, PNG, TIFF, INX, XPS files. By using OSDC with groupware, webmail systems, etc., Microsoft Office and RTF documents can be easily converted even in environments where Microsoft Office and Adobe software are not installed.
.NET, COM, Java, and C/C++ are available as standard application interfaces.
Although it is extremely difficult to perform high-precision conversions without using Microsoft Office, Antenna House has over 30 years of experience in developing Office conversion tools that make it possible.
Since Office Server Document Converter was launched in 2005 (formerly known as Server Based Converter), Antenna House has continuously worked to improve the accuracy of the conversion.

Other Features
OSDC direct conversion is a method that does not use the application from which the document was created, nor does it use printer drivers.
Since Microsoft Office automation is not used on the server side, conversions can be done without worrying about its risks or licensing issues when used in the cloud.
There is no need to install Microsoft Office, Adobe software, OpenOffice or LibreOffice to convert Office documents.
Fast conversion to various output formats is possible even in Linux environments.
Additional Features
OSDC V8.0 or later supports Amazon Graviton2 processors.

BIDI (bidirectional text) is the mixing of right-to-left characters, such as Arabic and Hebrew, and left-to-right writing, such as English.
There are two types of characters: right-to-left (rtl), as in Arabic and Hebrew, and left-to-right (ltr), as in Latin. Also, parentheses and symbols are not directional (neutral). BIDI processing is a mechanism for controlling the directionality of characters in a paragraph in which these characters are mixed and bidirectional, such as the direction of neutral characters.
This allows OSDC to display documents with a large number of languages and characters mixed together.
Effective October 1, 2019, Microsoft licensing terms for dedicated hosted cloud services have been revised. As a result, we have received numerous inquiries from those who planned to use on-premise licensing in a shared cloud environment regarding the operation of their document management systems, particularly how to convert documents.
Please see the following page for more information on the impact of Microsoft's revised licensing terms and the usefulness of Office Server Document Converter in a non-Microsoft licensed environment. Office Server Document Converter can solve your problems.
