Question details

The user wants to send a PDF form for signature and include supporting attachments separately, rather than merging them into the main PDF document.

How to Attach Files to an Adobe Acrobat Signature Request

Product: Adobe Acrobat Sign
Device & OS: not provided
Scenario: Sending a transmittal form for e-signature while delivering related documents to the recipient in the same transaction.
Observed behavior: The user needs a method to keep attachments distinct from the main PDF signature document to avoid embedding them directly as extra pages.

Before you start

Ensure you have the final version of your main PDF transmittal form ready, and gather all supporting documents you wish to attach separately in a single folder for easy access during the upload process.

Use Adobe Acrobat Sign to Add Separate Attachments

Send your PDF for signature using Acrobat Sign, which allows you to include distinct supporting files in the same transaction without merging them into the primary form.

By utilizing the specific file attachment features within the Acrobat Sign interface rather than the standard PDF combination tools, you can keep your signature document clean while still providing all necessary context to the signer.

Prepare the primary document

Open Adobe Acrobat and prepare your main transmittal form as a standard PDF. Ensure all signature fields are properly placed.

Initiate the signature request

Navigate to the 'Adobe Acrobat Sign' tool (or select 'Request e-signatures') to start the sending process.

Add recipient details

Enter the recipient's email address and customize the signature request message that will appear in their email.

Attach supporting files

Look for the specific 'Add Files' or attachment option within the signature request interface. Use this to upload your separate supporting documents, avoiding the standard 'Combine Files' tool.

Send and verify

Send the request. The recipient will receive the main document to sign alongside the separate attachments in the same email transaction. Ensure they can access both files upon receipt.

Verification Tip: Always double-check the final transaction preview before sending to ensure the supporting files are listed as distinct attachments and have not been accidentally appended as extra pages to your main signature form.

Frequently Asked Questions

Can I prevent recipients from editing the attached files in a signature request?

Yes, if you convert your supporting documents to secure PDFs with restricted editing permissions before attaching them, recipients will be able to view them but cannot make unauthorized changes.

Why did my attachments merge into the main PDF instead of staying separate?

This usually happens if you use the 'Combine Files' or 'Add Documents' feature in your PDF editor instead of specifically using the attachment function within the e-signature request interface.

Is there a file size limit when attaching documents to an Acrobat signature request?

Yes, most e-signature platforms have a maximum transaction size limit (often between 10MB to 25MB). If your separate attachments exceed this limit, you may need to compress the files before uploading them.
