Many people expect to verify the authenticity of a PDF file quickly without long checks. Adding a QR code signature to a PDF provides a practical solution. A scannable code makes it easier for clients, colleagues, or vendors to confirm who signed the document and when. Instead of printing a PDF and signing it manually, you can automate the signing process using the simple, Node.js REST API-powered setup. This guide offers a step-by-step explanation of how to sign PDF files with QR codes in Node.js applications. You do not require an advanced technical background to integrate this functionality, which reduces repetitive tasks and keeps documents tamper-resistant.

Steps to Sign PDF With QR Code Signatures Using Node.js

1. Import and set up GroupDocs.Signature Cloud SDK for Node.js
2. Obtain the API credentials and initialize SignApi with them
3. Add the source PDF file with FileInfo
4. Create a QR code signature and configure the properties using SignQRCodeOptions
5. Define the output file and e-signature settings with SignSettings
6. Send a PDF signing request and execute it with the createSignatures method

When you sign a PDF document with a QR code in Node.js using the outlined steps, you make verification much more convenient. The REST API enables developers to check the signer’s details or the document’s purpose without needing special software. This is helpful for teams that work across different locations or rely on shared digital workflows. You can customize the appearance, size, and placement of the QR code on a page. This flexibility works well for documents that require repeated signing owing to the process consistency. With the cloud-based API, you can handle PDF signing tasks from anywhere without installing full PDF editors or heavy tools.
