Users are experiencing an issue where completed and signed PDFs fail to attach when sent via email directly from the Fill & Sign app.

Fix Missing PDF Attachment When Emailing from Fill & Sign on iPad

Product: Document Cloud PDF Services / Fill & Sign
Device & OS: iPad
Scenario: Attempting to share or email a completed and signed PDF document directly from within the application.
Observed behavior: The email draft opens and sends successfully, but the signed PDF document is completely missing from the email attachments.

Before you start

Ensure your iPad has a stable internet connection and that your default Mail app is properly configured with an active email account before attempting to share documents.

Solution 1Recommended

Save the PDF Locally Before Emailing

Manually saving the completed PDF to your iPad ensures the file is fully processed and rendered before it is attached to an email.

Often, using the direct 'Mail' option from a share menu causes a handoff timeout, meaning the email draft opens before the PDF finishes generating. Saving it first forces the app to render the complete file.

Complete your document

Finish filling out all necessary fields and adding your signature in the Fill & Sign iPad app.

Save to Files

Instead of immediately tapping the Mail icon in the share sheet, choose the 'Save to Files' option and select a folder on your iPad or iCloud Drive.

Attach manually

Close the app, open your iOS Mail or preferred email application, compose a new message, and use the attachment button to select the saved PDF from your Files.

Verify Attachment: Always look for the physical PDF icon or preview box inside the email draft before hitting the send button to confirm it is successfully attached.

Solution 2

Update the App and Check Permissions

Software bugs in older versions of the app or restrictive iOS settings can prevent the application from sharing files properly.

Frequently Asked Questions

Why do my PDF attachments disappear when using the iPad Share Sheet?

This usually happens due to a rendering timeout. The iOS Share Sheet hands the task off to the Mail app before the PDF application has finished generating the signed document, resulting in an empty email draft.

How do I know if my PDF is actually attached to my email?

In the Mail compose window on your iPad, you should clearly see a document icon or a thumbnail preview representing the PDF file. If you only see text or blank space below your message, the attachment process failed.

Can I use WPS Office to sign PDFs created in other applications?

Yes, WPS Office is fully compatible with standard PDF formats. You can open, read, edit, and sign PDF files originally created in any other application, ensuring smooth document management across different platforms.
