Question details
A user wants to create a PDF form with a field that allows signers to upload or attach files like scanned passports, licenses, or photos.

- Device & OS
- not provided
- Scenario
- Collecting identity documents or photos securely from clients during a form-filling process.
- Observed behavior
- Standard PDF forms lack a universally supported built-in file upload field for collecting attachments from signers.
Consider the privacy and security regulations (like GDPR or HIPAA) required for handling sensitive identity and financial documents before choosing your document collection method.
Use a Secure Web Form or Document Portal
Since standard PDF forms do not universally support file uploads, transitioning to a secure web form is the most reliable method.
Standard PDF specifications do not include a native 'file upload' form field that works across all PDF readers. Attempting to force attachments inside a PDF often results in compatibility issues when the signer uses a mobile device or a non-standard PDF viewer.
Select a web-based form platform or specialized CRM that supports secure file uploads and data encryption.
Drag and drop the 'File Upload' control into your web form so clients can easily attach their passport or ID images.
Ensure the uploaded files are stored securely and access is restricted only to authorized personnel.

Enable PDF File Attachments via Desktop Workflows
If you must use a PDF, you can instruct users to use the built-in attachment feature in professional desktop PDF readers, though this is not a seamless form field.
Use WPS Office to Manage Forms and PDF Attachments
WPS PDF provides comprehensive tools to edit PDF text, handle interactive forms, and manage document attachments seamlessly, ensuring you can process client information efficiently.
- 1. Open your PDF in WPS Office: Launch WPS PDF and open the form you need to send or review.
- 2. Access the attachment tool: Go to the 'Insert' or 'Comment' tab and look for the 'Attachment' (paperclip) icon to add supporting documents.
- 3. Embed the passport or photo: Select the scanned passport or photo file from your local drive to embed it directly into the PDF.
- 4. Secure the document: Go to the 'Protect' tab to encrypt the PDF with a password before sharing sensitive data.

Frequently Asked Questions
Why isn't there a file upload button in standard PDF forms?
The PDF specification was originally designed for print formatting and basic text/choice data entry. Native file upload controls require server-side processing and live storage, which static PDF files cannot natively execute across all third-party PDF readers.
Can signers attach photos to a PDF on their mobile phones?
Most default mobile PDF viewers do not support embedding file attachments into existing PDFs. Users would need a dedicated, advanced PDF application to attach files, which is why secure web forms are highly recommended for mobile users.
Is it safe to collect credit card photos via PDF attachments?
Collecting unencrypted credit card images via email and standard PDFs is highly insecure and often violates PCI-DSS compliance. You should use a dedicated, secure payment gateway instead.
