Universal Document & File Conversion Libraries

Conholdate.Total is a set of powerful file conversion libraries that support conversion between a wide variety of document and image types, including Microsoft Office and OpenDocument formats, PDFs, HTML, CAD, and raster images. It offers customizable conversion options, such as the ability to convert whole documents or specific page ranges, add watermarks, and extract document information. Conholdate.Total can be used independently of other third-party applications, and its caching system increases conversion performance while minimizing resource usage. The library is scalable, can be easily deployed with any .NET & Java application, and offers a simple and intuitive public API.


Convert Between a Wide Range of File & Document Formats

Conholdate.Total empowers you to build an incredibly versatile document conversion system capable of handling many popular file formats including Microsoft Word documents, Excel spreadsheets, PowerPoint presentations, Outlook message and storage files, Project files, Visio diagrams, OneNote files, Adobe PDF documents, OpenOffice documents, Raster & Vector image files, 3D & CAD files & HTML.

Apply Watermark to the Converted Documents

Conholdate.Total allows to add a watermark to the converted document with several options to control how the watermark will be stamped, including text, font, color, width, height, position (top and left), rotation angle, transparency, and whether the watermark is laid on top or bottom of the document.

Extract Document Information

Conholdate.Total offers a standard method of obtaining source document information, which is independent of the way the document was loaded. The resulting object provides additional information depending on the format type, such as title, author, encryption status, start and end dates of project management documents, number of tasks, width and height of images, and layout and layer collections of CAD drawings. It also includes the count of lines and words, whether the document is password protected, and the number of worksheets in spreadsheets. Additionally, for PDF documents, the object may include a table of contents. For emails, the object may include information about the number and names of attachments, whether the email is encrypted or signed, and whether its body is in HTML format.

Accelerate Document Conversion with Caching

Conholdate.Total provides a caching mechanism for time-consuming document conversion operations. This means that the converted document is stored in the cache (e.g. on the local drive) and can be retrieved from there in case of repetitive conversions of the same document. This can save time and improve performance, especially for large and complex documents.

Microsoft Office Automation Not Needed for Office Formats

Conholdate.Total is built using managed code that never needs Microsoft Office to be installed on the machine to work with supported document formats. It is a perfect Microsoft Office automation alternative in terms of supported features, security, stability, scalability, speed and price.
