GroupDocs.Conversion provides PdfLoadOptions to give you control over how the source PDF document will be processed. The following options could be set:
| Option | Description |
|---|---|
| Format | The document type is auto-detected during loading, however, you can specify explicitly the type of the source document. Available options are: Pdf, Epub, Xps, Tex, Ps, Pcl |
| DefaultFont | A default font for PDF document. The specified font will be used if a font is missing. An absolute path to the font file must be provided. |
| FlattenAllFields | Specifies that all fields in the source document should be flattened during conversion. |
| FontSubstitutes | Substitute specific fonts from the source document. |
| HidePdfAnnotations | Specifies that annotations in the source document should be hidden. |
| Password | A password to unlock the protected document. |
| RemoveEmbeddedFiles | Whether to remove the embedded files from the source document during the conversion. |

WordProcessingConvertOptions options = new WordProcessingConvertOptions();
converter.Convert("converted.docx", options);

GroupDocs.Conversion for .NET allows you to set a default font name when a font is not available in the document. You can use the DefaultFont property of the PdfLoadOptions class to set the default font name. In case the DefaultFont property is not set the Times New Roman font will be used. The following code snippet shows how to set a default font name when converting from PDF to word-processing document:
Contracts.Func<LoadOptions> getLoadOptions = () => new PdfLoadOptions
{
DefaultFont = "Helvetica"
};
using (Converter converter = new Converter("sample.pdf", getLoadOptions))
{
WordProcessingConvertOptions options = new WordProcessingConvertOptions();
converter.Convert("converted.docx", options);
}
The following code snippet shows how to convert a PDF document and specify font substitution for missing fonts:
Contracts.Func<LoadOptions> getLoadOptions = () => new PdfLoadOptions
{
FontSubstitutes = new List<FontSubstitute>
{
FontSubstitute.Create("Tahoma", "Arial"),
FontSubstitute.Create("Times New Roman", "Arial"),
}
};
using (Converter converter = new Converter("sample.pdf", getLoadOptions))
{
PdfConvertOptions options = new PdfConvertOptions();
converter.Convert("converted.docx", options);
}
