Why Adobe Sign Removes Acrobat Calculation Fields and Scripts
Question details
Converting an Acrobat PDF form into an Adobe Sign form strips away automatic calculation scripts, preventing fields from multiplying or auto-populating values.
- Product
- Adobe Acrobat / Adobe Sign
- Device & OS
- not provided
- Scenario
- A user is trying to process an interactive PDF form through the Adobe Sign tool for an urgent work project, expecting it to calculate fields automatically before or during signing.
- Observed behavior
- All JavaScript and mathematical functionality is lost as soon as the PDF is converted and processed through the Adobe Sign cloud service.
Before proceeding, evaluate whether your workflow strictly requires the use of Adobe Sign's cloud-based routing, or if standard digital signatures applied locally can meet your compliance requirements.
Retain Form Calculations by Using Digital Signature Fields
Bypass the Adobe Sign cloud conversion entirely and use traditional digital signature fields within the Acrobat PDF environment to preserve all JavaScript functions.
Adobe Sign and Acrobat PDF JavaScript calculation features are mutually exclusive during conversion. The cloud-based Adobe Sign tool strips active scripts for security and standardization across web viewing platforms.
If your form heavily relies on machine rates, minutes, or other automatic calculations, the most reliable method is to keep the document as a standard interactive PDF.
Do not upload or convert the document using the 'Send for Signature' or Adobe Sign web tools. Keep it saved as a standard interactive PDF file.
Open the PDF editor's form preparation tools and manually add a 'Digital Signature' field to the document layout where the signature is required.
Email or share the PDF directly with your signees. They can fill out the fields, trigger the calculations locally on their machine, and sign the document using a certificate-based digital signature.
Move Calculations to a Web Form Before Signing
If Adobe Sign must be used for signature routing, handle the calculations on a separate server or web form before pushing a flattened document to Adobe Sign.
Manage PDF Forms and Signatures Seamlessly with WPS Office
If you are frustrated by script removals and complex cloud conversions, WPS Office offers a straightforward way to fill interactive forms, allow native calculations, and securely sign PDFs directly from your desktop.
- 1. Open the Form in WPS PDF: Launch WPS Office and open your interactive PDF form that contains calculation fields.
- 2. Fill and Calculate Offline: Input your data directly into the form. WPS PDF allows native field interactions so calculations will update in real-time.
- 3. Access the Signature Tool: Navigate to the 'Fill & Sign' or 'Protect' tab on the top ribbon and select 'Sign'.
- 4. Create and Apply Signature: Create your signature and place it onto the designated field without triggering any cloud-based script removals.
- 5. Save and Distribute: Save the finalized document locally and share the securely signed PDF via email.
Frequently Asked Questions
Why does Adobe Sign remove JavaScript from PDFs?
Adobe Sign flattens forms and removes active JavaScript to ensure strict security, prevent malicious code execution, and guarantee that the document appears identically on all web browsers and mobile devices.
Can I use basic mathematical calculations in Adobe Sign?
Yes, but not using Acrobat's native JavaScript. Adobe Sign has its own specific text tag calculations and formula fields that must be set up within the Adobe Sign web authoring environment.
Will digital signature fields also remove my PDF calculations?
No. Standard certificate-based digital signature fields applied locally within a desktop PDF editor do not strip scripts. It is specifically the Adobe Sign cloud conversion process that removes the functionality.
Is there an easy workaround to keep my Acrobat scripts?
The easiest workaround is to avoid Adobe Sign entirely. Keep the document as an interactive Acrobat PDF and ask recipients to sign it using standard digital signatures.
