- Product
- Adobe Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- A user with an Acrobat Pro DC subscription and a cloud-based signature provider needs to digitally sign a PDF document.
- Observed behavior
- The Add Digital Signature option is missing from the Fill & Sign workflow. Additionally, form fields may display an unexpected highlight color.
Ensure that your cloud-based digital signature provider (e.g., InfoCert) is properly configured and that your Adobe Acrobat Pro DC software is up to date.
Use the Certificates Tool for Digital Signatures
Bypass the Fill & Sign tool and use the dedicated Certificates tool to apply a cloud-based digital signature.
The Fill & Sign feature in Adobe Acrobat is intended for basic electronic signatures. To use a secure, certificate-based cloud signature, you must use the specific Certificates workflow.
Open your PDF document in Acrobat Pro DC, click on the Tools tab at the top of the window, and select Certificates.
Click on Digitally Sign from the Certificates toolbar that appears at the top of your document view.
Click and drag your mouse cursor to draw the rectangular area where you want your digital signature to be displayed on the page.
Follow the on-screen prompts to select your configured cloud signature provider to complete the authentication and signing process.

Adjust Form Field Highlight Preferences
Disable or modify the background highlight color applied to signature and form fields in your PDF viewer.
A Faster Way to Sign PDFs with WPS Office
WPS Office provides an intuitive and comprehensive PDF editor that lets you easily insert electronic signatures, fill out forms, and manage documents without navigating complex menus.
- 1. Open Your PDF Document: Launch WPS Office and open the PDF file you need to review and sign.
- 2. Access the Fill & Sign Feature: Navigate to the PDF tab and select the Fill & Sign tool from the top menu.
- 3. Create Your Signature: Click on the Sign option to draw, type, or upload an image of your signature.
- 4. Place and Save: Drag the newly created signature to the correct location on the page, adjust its size, and save your document.

Frequently Asked Questions
Why is the digital signature option missing from Adobe Fill & Sign?
The Fill & Sign tool is explicitly built for standard electronic signatures. For secure, certificate-based or cloud-based digital signatures, Adobe requires you to use the dedicated Certificates tool instead.
Can I use a cloud signature provider like InfoCert in Adobe Reader?
Yes. If the PDF document has already been prepared with a designated digital-signature field, you can open it in the free Adobe Reader and simply click the field to choose your available cloud signature provider.
How do I remove the blue background color from PDF signature fields?
The background color is a local form highlight feature. You can turn it off by navigating to Edit > Preferences > Forms (or Acrobat > Preferences > Forms on a Mac) and modifying the highlight settings. This only affects your view, not the actual file.
