PDF XChange Editor is a powerful PDF editing tool, and one of its key features is the ability to add and edit signatures. This comprehensive guide will walk you through the process step-by-step, ensuring you can confidently manage your digital signatures within the software. Whether you need to add a new signature, modify an existing one, or remove a signature entirely, this guide has you covered.
Understanding Signature Types in PDF XChange Editor
Before we dive into the editing process, it's crucial to understand the types of signatures supported by PDF XChange Editor. Primarily, you'll encounter two main types:
- Image-based signatures: These are simply scanned images of your handwritten signature. They are easy to create but offer less security than digital signatures.
- Digital signatures: These are cryptographically secured signatures that verify the authenticity and integrity of the document. They provide a much higher level of security and are generally preferred for legally binding documents.
This guide will cover editing both types, though the process differs slightly.
Adding a New Signature
Let's start with adding a new signature to your PDF. There are two main ways to do this:
1. Adding an Image-Based Signature:
- Scan your signature: Use a scanner or your phone's camera to capture a clear image of your handwritten signature on a white background.
- Open PDF XChange Editor: Launch the software and open the PDF document you wish to sign.
- Access the Signature Tool: Navigate to the "Signature" tool within the editor's toolbar. The exact location might vary slightly depending on your version.
- Insert Image: Select the option to insert an image signature. You will then be prompted to browse and select the image file of your signature.
- Place and Resize: Click on the document where you want to place your signature and adjust its size as needed.
2. Adding a Digital Signature (requires a digital ID):
- Obtain a Digital ID: You'll need a digital ID (certificate) from a trusted Certificate Authority (CA). This is essential for creating a secure digital signature.
- Import Digital ID: Within PDF XChange Editor, import your digital ID. The exact steps may vary based on your version, but look for options related to "Digital IDs" or "Certificates" within the settings or signature tools.
- Sign the Document: Once your digital ID is imported, use the "Digital Signature" tool in PDF XChange Editor to sign the document. You will be prompted to select your digital ID and potentially add a reason or location for the signature.
Editing Existing Signatures
Editing existing signatures depends on whether it's an image-based or digital signature.
Editing Image-Based Signatures:
- Select the Signature: Click on the signature you wish to edit within the PDF.
- Edit Properties: Once selected, you may find options to resize, rotate, or even replace the image signature with a new one. Look for contextual menus or toolbars that appear after selecting the signature.
- Delete the Signature: If you need to remove the signature completely, simply select it and press the Delete key.
Editing Digital Signatures:
Important Note: Editing a digital signature is generally not recommended and can compromise its security and validity. If you need to make changes, it's best to delete the existing signature and create a new one. This will maintain the integrity of the digital signature. In most cases, you cannot directly edit the content of a digital signature itself.
Removing Signatures
Removing signatures is straightforward, regardless of type:
- Select the Signature: Click on the signature you want to remove.
- Delete: Press the Delete key on your keyboard, or use the appropriate "Delete" or "Remove" command within the editor's interface.
Troubleshooting Common Issues
- Signature Not Showing: Ensure the signature image is correctly imported and placed within the PDF document's layers. Check the visibility settings.
- Signature Too Large or Small: Resize the signature using the appropriate editing tools after placing it.
- Digital Signature Errors: Ensure your digital ID is valid and correctly imported. Contact your CA if you encounter persistent errors.
