Solution 1Recommended

Sign PDFs Individually using Fill and Sign

Since batch processing is not natively supported for visual signatures due to security constraints, you must apply them manually to each document.

Signatures saved in the Fill and Sign tool are intentionally restricted from automation tools like the Action Wizard. This prevents unauthorized bulk stamping of your signature without explicit consent for each file.

1
Open the Document

Launch your PDF editor and open the first PDF file you need to sign.

2
Access Fill and Sign

Navigate to the tools menu and select the 'Fill & Sign' option.

3
Place the Signature

Click the 'Sign' icon, choose your previously saved signature, and click on the document to place it.

4
Save and Repeat

Save the signed PDF document, close it, and repeat the process for the remaining files.

Alternative visual markers: While you cannot batch apply signatures, you can batch apply watermarks. However, watermarks are not recommended as a substitute for signatures because they lack the required security and intent of signing.

Frequently Asked Questions

Can I use a watermark as a batch signature?

While you can technically batch-apply watermarks to multiple PDFs, watermarks are generally used for indicating document status (like 'Draft' or 'Confidential'). They are placed across the entire document and do not provide the authentication, intent, or security of a proper signature.

Why can't I use the Action Wizard for Fill and Sign?

The Fill and Sign signature is stored exclusively for manual use within that specific tool. This is a deliberate security measure to prevent the automated, unauthorized stamping of your signature across documents. Consequently, automated batch features like the Action Wizard cannot access this stored visual signature.

Are visual Fill and Sign signatures legally binding?

A basic Fill and Sign visual signature is generally acceptable for informal agreements and internal documents. However, for strict legal compliance and high-security transactions, you should use certified digital signatures that cryptographically verify your identity and track document modifications.
