Why Adobe Sign Text Tags Are Not Visible in a Local PDF
Question details
The user needs to understand why Adobe Sign text tags can only be seen when the document is processed through Adobe Sign, but remain invisible or act unexpectedly when the PDF is opened on a local computer.

- Product
- Adobe Sign
- Device & OS
- not provided
- Scenario
- Reviewing and preparing a PDF document locally with embedded signature tags before uploading it to an e-signature service.
- Observed behavior
- Text tags intended for Adobe Sign do not render as interactive form fields when the PDF file is opened directly in a local PDF viewer.
Ensure you are using the correct text tag syntax for Adobe Sign, and verify whether the document author intentionally changed the font color of the tags to match the background to hide the raw text.
Process the Document Through Adobe Sign
Since text tags are a proprietary Adobe Sign feature, they must be processed by the Adobe cloud environment to become visible, interactive signature fields.
Adobe Sign utilizes specific text syntax (e.g., {{sig_es_:signer1:signature}}) to determine where to place signature fields. Standard local PDF readers treat these tags as plain text.
To prevent signers from seeing raw syntax, document creators often change the text color to white so it blends with the document background. This makes the text invisible locally, but the Adobe Sign system still reads the hidden text and converts it into proper form fields.
Access your Adobe Sign web portal through your browser.
Select the PDF file from your local computer and upload it to the platform.
Check the 'Preview & Add Signature Fields' option before sending. The cloud processor will parse your hidden text tags and display the interactive signature boxes correctly.
If tags are still not rendering properly, visit the Adobe Sign Support Forum for troubleshooting syntax and specific required-field parameters.

Frequently Asked Questions
Why does my text tag appear as plain text in my local PDF viewer?
Standard desktop PDF viewers cannot interpret Adobe Sign's proprietary syntax. They will simply display the raw text (like {{sig_es_:signer1}}) until the document is uploaded and parsed by Adobe Sign servers.
Can I test Adobe Sign text tags without actually sending the document?
Yes. When setting up your document in Adobe Sign, select the 'Preview and Add Signature Fields' checkbox. This lets you view the parsed tags and ensure they are rendering correctly before routing it to recipients.
Why did my text tags completely disappear when I opened the file locally?
It is a common practice to change the font color of text tags to match the page background (usually white) so the raw syntax is invisible to the reader. The text is still there, but you won't see it until Adobe Sign converts it into a signature block.
