Formats and Conversion

Updated on Mar 5, 2026

RadWordsProcessing does not need any external dependencies in order to convert documents from/to the supported formats. The document model is independent from UI and can be used on the server side as well as on the client.

You can use RadWordsProcessing to convert among variety of formats.

As of Q4 2024 RadWordsProcessing offers timeout mechanism for import and export of documents. The new Import and Export methods for all FormatProviders have a mandatory timeout parameter. The old Import and Export methods are Obsolete now.

Below you can see a feature / format matrix that describes supported features by file format. The currently supported formats are:

• Docx
• Doc & Dot (import only)
• Rtf
• Html
• Pdf (export only)
• Plain text - plain text is excluded from the comparison.
