How do I attach a file to a PDF using Adobe Acrobat?

Open your PDF in Acrobat. Go to Edit and then Link. Choose the option to attach a file. Select your file and add it.

If my attached file has sensitive information, what should I do before sharing the PDF?

Check the attachment for private or sensitive data. Sanitize the PDF to remove or hide this information. Only share after making sure all sensitive info is gone.

Why should I use attachments instead of sending separate files with my PDF?

Attachments keep all files in one PDF, so nothing gets lost. It is easier for the receiver to find and open related files. You avoid sending many separate emails or downloads.

How is attaching a file to a PDF different from adding a link in Adobe Acrobat?

Attaching a file Adding a link. The file is saved inside the PDF. The link connects to a web page or another file location. The attachment travels with the PDF. The link may not work if the target file moves or is deleted. Good for keeping all related files together. Good for quick access to outside resources.
