How to Fix Acrobat Request Signatures Removing Existing Signature Fields
Question details
The user is experiencing an issue where pre-existing signature fields disappear when uploading a PDF from the desktop application to the web for a signature request.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Uploading a PDF to Acrobat Web to send a signature request.
- Observed behavior
- Signature fields created in the desktop application are unexpectedly removed or invisible on the web platform.
Ensure you have a backup copy of your original PDF with the signature fields intact before attempting any troubleshooting or uploading it to web platforms.
Switch Back to the Classic E-Signing Experience
Reverting to the classic e-signing interface often resolves compatibility issues between desktop and web signature fields.
In some cases, the updated e-signing experience may have parsing conflicts with fields created in desktop environments. Switching to the classic interface can bypass this web rendering bug.
Open Acrobat on the web, log into your account, and click on your profile icon in the upper right corner.
Select 'Settings' from the dropdown menu and scroll down to the 'E-Signing settings' section.
Look for the option to revert to the classic e-signing experience and apply the change before uploading your document again.

Test the Workflow with a Clean Document
Isolating the issue by using a blank or non-confidential file helps determine if the problem is document-specific.
Add Signature Fields Directly in the Web Interface
If desktop fields fail to sync, manually adding the fields during the web request process ensures they appear correctly for the recipient.
Sign PDFs Reliably with WPS Office
Avoid web sync issues by managing and applying your PDF signatures directly within WPS Office. It offers a powerful, built-in PDF editor to handle all your document signing needs securely and without losing formatting.
- 1. Open the PDF: Launch WPS Office and open the PDF document that requires a signature.
- 2. Access the signature tool: Navigate to the 'Protect' or 'Edit' tab at the top of the interface and select 'PDF Signature'.
- 3. Create your signature: Create a new signature by drawing it, typing your name, or uploading an image of your signature.
- 4. Place the signature: Click on the document area where you want the signature to appear, then drag to adjust its size and position.
- 5. Save the document: Save the signed PDF locally to finalize the changes before sharing it directly with your recipients.

Frequently Asked Questions
Why do my PDF signature fields disappear when uploading?
This usually happens due to parsing differences between the desktop software that created the fields and the web platform's rendering engine, or if the PDF was accidentally flattened before the upload process.
Can I recover signature fields that were removed during an upload?
If the interactive fields were stripped during the web upload, they cannot be recovered within that web session. You will need to either re-upload the original unflattened desktop file or manually re-add the fields in the web interface.
How do I stop PDFs from flattening my form fields?
Ensure you use the 'Save As' function rather than 'Print to PDF' when saving your document. Printing to PDF acts as a physical printer emulator and permanently flattens interactive elements like text boxes and signature fields into static images.
Are PDF signatures created offline legally binding?
Yes, electronic signatures applied using standard, secure offline PDF software like WPS Office are widely recognized as legally binding for most business and personal transactions, provided all parties agree to use electronic records.
