How to Fix Fillable PDF Fields Disappearing in Acrobat Mobile App
Product
Adobe Acrobat Mobile App
Device & OS
Mobile (iOS/Android)
Scenario
Sending a cloud copy of a fillable PDF for signature or sharing via the mobile app.
Observed behavior
The fillable fields are visible and work correctly on the desktop version, but the pre-created fields disappear or flatten when the cloud copy is sent from the mobile application.
Before you start

Ensure your mobile PDF application is updated to the latest version and verify whether the document is password-protected, as security restrictions can interfere with form fields during mobile sharing.

Solution 1Recommended

Verify Document Security and Mobile Sharing Workflow

Check for password protection and confirm the exact sharing option used on the mobile device, as certain workflows may automatically flatten PDF forms.

When sharing PDFs from mobile devices, applications sometimes flatten the document to ensure the recipient can view it, which removes the interactive fields. It is critical to differentiate between sending a file as an attachment and sending it via a dedicated signature tool.

1
Check for password protection

Open the original fillable PDF on your desktop and navigate to Document Properties > Security to ensure no passwords or restrictions are preventing editing or form filling.

2
Verify the mobile sharing option

On your mobile device, determine whether you are using the 'Share PDF' option (which may flatten fields) or a dedicated feature like 'Adobe Acrobat Sign'.

3
Share as a cloud link

Instead of sending a direct file attachment, try using the 'Create Link' or 'Share Link' feature to send access to the cloud copy, preserving the interactive form fields.

Workflow Differences: The desktop and mobile versions of PDF editors often handle form fields differently. Comparing the exact steps taken on the desktop with the mobile app can help pinpoint where the flattening occurs.

Frequently Asked Questions

Why do fillable PDF fields disappear when viewed on a mobile device?

Fillable fields often disappear on mobile devices if the default PDF viewer does not support interactive forms, or if the document was automatically 'flattened' by the sharing application to make the text visible across all platforms.

How can I prevent my PDF form fields from flattening?

To prevent flattening, share the document as a secure cloud link rather than an email attachment, or instruct the recipient to open the file using a dedicated PDF reader like WPS Office instead of a built-in browser viewer.

Does password protection affect PDF form fields on mobile?

Yes, high-level security restrictions or password protection can limit functionality on mobile apps. If the mobile app cannot authenticate the permissions properly, it may restrict or hide editable fields.
