This on-premise .NET API lets your app end-users sign the electronic documents from a wide range of file formats. Supports several types of e-signing methods.
Document Signature Processing Features
- Create and add signatures to documents of various file formats.
- Specify visual attributes of signatures, such as color, font, margins, etc.
- Search and fetch a list of signatures from a document.
- Determine if the document contains signatures meeting specified criteria.
- Extract basic information about the document.
- Generate image representation of document pages for preview.
- Distinguish created signatures from the actual document.
- Put encrypted text into the QR-code signature or embed custom data objects.

Please check the GitHub Repository for other common usage scenarios.
Sign a PDF File and Save it in DOCX Format using C# Code
using (Signature signature = new Signature("sample.pdf"))
{
// create QRCode option with predefined QRCode text
QRCodeSignOptions signOptions = new QRCodeSignOptions("JohnSmith")
{
EncodeType = QRCodeTypes.QR,
Left = 100,
Top = 100
};
PdfSaveOptions pdfSaveOptions = new PdfSaveOptions()
{
FileFormat = PdfSaveFileFormat.DocX,
OverwriteExistingFiles = true
};
// sign document to file
signature.Sign("SignedPdf.docx", signOptions, pdfSaveOptions);
}
Use C# to Search and Delete Signatures from a DOCX File
// initialize Signature instance
using (Signature signature = new Signature("signed.docx"))
{
BarcodeSearchOptions options = new BarcodeSearchOptions();
List<BarcodeSignature> signatures = signature.Search<BarcodeSignature>(options);
List<BaseSignature> signaturesToDelete = new List<BaseSignature>();
// collect signatures to delete
foreach (BarcodeSignature temp in signatures)
{
if (temp.Text.Contains("John"))
{
signaturesToDelete.Add(temp);
}
}
// delete signatures
DeleteResult deleteResult = signature.Delete(signaturesToDelete);
if (deleteResult.Succeeded.Count == signaturesToDelete.Count)
{
Console.WriteLine("All signatures were successfully deleted!");
}
else
{
Console.WriteLine($"Successfully deleted signatures : {deleteResult.Succeeded.Count}");
Console.WriteLine($"Not deleted signatures : {deleteResult.Failed.Count}");
}
Console.WriteLine("List of deleted signatures:");
foreach (BaseSignature temp in deleteResult.Succeeded)
{
Console.WriteLine($"Signature# Id:{temp.SignatureId}, Location: {temp.Left}x{temp.Top}. Size: {temp.Width}x{temp.Height}");
}
}
