How to Use a Typed Signature in an Acrobat XI Fillable Form
Question details
The user wants to enter a typed signature instead of a certificate-based digital signature in an Acrobat XI fillable form.

- Product
- Adobe Acrobat XI
- Device & OS
- not provided
- Scenario
- Filling out a PDF form that originally requires a digital certificate signature.
- Observed behavior
- The form restricts the user to a certificate-based digital signature, preventing them from simply typing their name.
Ensure you have editing permissions for the PDF form, as changing form fields requires modifying the document's underlying structure.
Replace the Digital Signature Field with a Text Field
Modify the form by swapping the restrictive digital signature field for a standard text field to allow typed signatures.
Acrobat's built-in digital signature fields strictly require a cryptographic certificate. To bypass this and allow users to type their name, you must edit the form's layout and replace the signature field with a standard text box.
Open the PDF form in Adobe Acrobat XI and select 'Tools' > 'Forms' > 'Edit' to enter form editing mode.
Locate the existing digital signature field on the document, right-click it, and select 'Delete'.
From the Forms toolbar, click 'Add New Field' and choose 'Text Field'. Click and drag on the document to place it where the signature field used to be.
Name the new text field 'Signature' in the properties box, close form editing mode, and save your document. Users can now click the field and type their name.

Add Typed Signatures to PDFs with WPS PDF
WPS Office includes a powerful PDF editor that allows you to easily insert typed, drawn, or image-based signatures into any PDF document without needing complex certificate configurations.
- 1. Open the PDF in WPS Office: Launch WPS Office and open your PDF document.
- 2. Access the Signature Tool: Navigate to the 'Insert' tab on the top ribbon and click on 'Sign' or 'PDF Signature'.
- 3. Create a Typed Signature: Click 'Create Signature', choose the 'Text' option, and type your name using your preferred font.
- 4. Place the Signature: Click 'OK', then click anywhere on the document to place your newly created typed signature.

Frequently Asked Questions
Why does my PDF form ask for a digital ID when I try to sign?
The creator of the form added a specific 'Digital Signature' field that requires cryptographic validation (a digital ID or certificate) rather than a simple text or image signature.
Can I just type my name if the form is locked?
If the PDF is locked or secured against editing by the author, you will not be able to delete the digital signature field or add a text field without the permissions password.
Is a typed signature legally binding?
In many jurisdictions, a typed signature can be legally binding for certain types of agreements, but highly sensitive documents often require certificate-based digital signatures to prove identity and prevent tampering. Always check with your legal or compliance team.
How do I add a signature without editing form fields?
You can use the 'Fill & Sign' tool in Acrobat or the 'PDF Signature' feature in WPS Office to place a text-based signature directly over the document, provided the document's security settings allow it.
