GroupDocs.Signature enables adding customized signatures to PDF files. Java developers can integrate signing functionality into their applications using our software.
// Load the document into a Signature instance
Signature signature = new Signature("input.pdf");
// Instantiate a QrCodeSignOptions object
QrCodeSignOptions options = new QrCodeSignOptions("QR code text");
// Configure all desired options
options.setLeft(100);
options.setTop(100);
options.setForeColor(Color.RED);
// Save the file with added QR code to the local disk
signature.sign("output.pdf", options);
Our e-signing API streamlines business processes. Sign, search, update, delete, and verify various signatures programmatically.
Easily place electronic signatures in any position on any page of a document. Enhance document content with text, images, barcodes, metadata, or digital certificates.
After signing, documents can be processed further. Retrieve a list of all signatures present, modify them, or delete them as needed.
Secure business documents against unauthorized changes with corporate digital certificates. Add or extract hidden metadata entries available in all document types.
// Provide the source document as a parameter
Signature signature = new Signature("input.pdf");
// Specify the image path in the signature options
ImageSignOptions options = new ImageSignOptions("image.jpg");
// Set the size and target pages for the signature
options.setVerticalAlignment(VerticalAlignment.Bottom);
options.setHorizontalAlignment(HorizontalAlignment.Right);
options.setHeight(150);
options.setWidth(200);
Padding padding = new Padding(50);
