- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Sending a prepared PDF document for electronic signature.
- Observed behavior
- The application stalls, freezes, or fails to complete the sending process.
Ensure your internet connection is stable and that your Adobe account subscription for e-signing services is currently active.
Restart Acrobat and Re-authenticate Your Account
Often, temporary network glitches or authentication issues cause Acrobat to stall when connecting to Adobe's signing servers.
Adobe's electronic signature service relies heavily on a stable connection to its cloud servers. If your session token expires or experiences a sync error, the application may freeze while trying to initiate the send protocol. Signing out and back in forces the software to establish a fresh, authenticated connection.
Open Adobe Acrobat, click on your profile icon in the top right corner, and select 'Sign Out'.
Close Adobe Acrobat completely. Ensure no background Acrobat processes are running, then reopen the application.
Click on 'Sign In' at the top right and enter your Adobe credentials to refresh your session.
Open your document and attempt to send it for signature again over a stable internet connection.

Check Document Settings, Fields, and File Size
Corrupted files, invalid email addresses for recipients, or overly large documents can prevent the signature request from sending.
Install the Latest Acrobat Updates
Outdated software might contain bugs that interfere with cloud-based features like e-signatures.
Send and Sign Documents Seamlessly with WPS Office
If Acrobat continues to stall, switch to WPS Office. The built-in WPS PDF tool allows you to easily add, request, and manage electronic signatures without the heavy processing load, ensuring your workflows remain uninterrupted.
- 1. Open your PDF: Launch WPS Office and open your document using the built-in WPS PDF editor.
- 2. Access the signature tool: Navigate to the 'Fill & Sign' or 'Protect' tab located on the top ribbon.
- 3. Add or request signatures: Use the 'Sign' feature to place your own signature, or prepare the document to be sent out for others to sign.
- 4. Save and share: Save the finalized document and share it instantly via email or cloud link.

Frequently Asked Questions
Why does Adobe Acrobat freeze when I click send for signature?
Acrobat typically freezes during this process due to a lost connection to Adobe's cloud servers, an expired login session token, or a corrupted PDF file that the system cannot process for the web.
Does file size affect the ability to send a PDF for electronic signature?
Yes, exceptionally large PDFs or those containing complex, unflattened layers can cause the signing service to time out or stall. Compressing the PDF before sending often resolves this issue.
Can I send a PDF for signature if my Adobe subscription expired?
No, sending documents for electronic signature requires an active Adobe Acrobat Pro or Adobe Sign subscription. If your account is downgraded to the free tier, the send feature will be disabled or fail to execute.
