Get supported file formats Leave feedback

With GroupDocs.Signature, you can retrieve the list of file formats that allow adding electronic signatures by following these steps:

1. Call the static function GetSupportedFileTypes of the FileType class.
2. Enumerate through the collection of FileType objects.

This will give you the supported document formats for adding electronic signatures. The following code sample demonstrates how to get supported file formats list.

    const supportedFileTypes = signatureLib.FileType.getSupportedFileTypes().toArray();

    supportedFileTypes.forEach((fileType) => {
        console.log('\n' + fileType.getExtension());
    });

You may easily run the code above and see the feature in action in our GitHub examples:
