Signing PDF documents with text is one of the simplest ways to validate digital files without complex certificates or third-party tools. Adding text signatures to PDFs enhances trust and professionalism. While working on a business proposal, confirming contract ownership, or marking an invoice as approved, automated PDF signing boosts efficiency. In this article, we’ll explore how to sign PDF files with text in Java web or desktop applications using the Java REST API. It allows users to create customized, verifiable signatures within a few easy steps.

Steps to Sign PDF With Text Signatures Using Java

1. Download the GroupDocs.Signature Cloud SDK for Java and create a Java project
2. Obtain and set up your API credentials using the Configuration class
3. To add text signatures to PDF, initialize the SignApi class
4. Add the source file using the FileInfo class
5. Use SignTextOptions to configure the text signature and set its properties
6. Define the e-sign settings using SignSettings
7. Create and execute the signing request with the createSignatures() method

By following these simple steps, users can quickly apply text-based signatures to PDF documents in Java without needing advanced programming knowledge. With the REST API, users can access the parameters to adjust font style, color, opacity, and alignment. It ensures every signed document meets your branding and compliance needs. There is no need for bulky installations or dependencies; users can perform document signing tasks from any platform that supports Java. The Cloud API is ideal for automating PDF approval systems, document authentication, or internal record management.
