GroupDocs.Conversion main feature is the ability to convert any document from any of supported source document formats into any supported target format (check the list of supported formats). All these conversions are possible without any additional software installed (like MS Office, Apache Open Office, Adobe Acrobat Reader and others). GroupDocs.Conversion provides a flexible set of settings to customize the conversion process to fulfill your needs:

Along with the whole document conversion to the desired target format, it could be useful to convert specific document pages or page ranges.

In some cases, the source file could be presented in a form of a byte stream, so the file extension is unknown. Luckily GroupDocs.Conversion for Node.js via Java is smart enough to detect source document format on the fly.

There are lots of modifications that are possible during the file conversion process:

• specify a password for password-protected documents;
• show/hide document comments and annotations;
• show/hide markup and track changes for Word documents;
• show hidden sheets when converting Excel files or not;
• set the text file encoding and many more;

You can obtain the complete list of possible conversions that are supported by GroupDocs.Conversion for Node.js via Java library. Also, it is possible to get allowed conversions for the specific file format.

It is a common use case when a source document references some specific fonts that are not present in the environment where you launch your application. GroupDocs.Conversion for Node.js via Java provides a solution - you can substitute missing fonts with fonts of your choice that will preserve your document appearance.

GroupDocs.Conversion allows to obtain basic information about source document - file type, pages count etc. Dependent on the source file type some format-specific information can be extracted, for example:

• CAD - list of layers and layouts in a CAD document;
• Email – list of attachments;
• PDF – title, author, table of contents and more;
• Project Management – project start and end dates.

With GroupDocs.Conversion you are not limited to local files only. It also supports loading documents from stream and remote URLs.
