Adobe Acrobat DC is the official subscription-based app for creating and managing PDF files. Both the Standard and Pro plans allow you to create fillable PDFs.  To learn how to get Adobe Acrobat, see How to Install Adobe Acrobat.     Adobe Acrobat Pro offers a free trial subscription. To sign up, follow this link to Adobe's website.    It's at the top of the app. It's the purple icon near the center of the window. This allows you to import your form from another file, such as a Word, Excel, or non-fillable PDF file into Acrobat. If you'd rather scan a paper document, click Scan a document, and then follow the on-screen instructions to import it from your scanner.    You can do this by double-clicking the document's name. If you want to require a digital signature, check the box next to "This document requires a signature."    This imports the file into Acrobat. The app will attempt to create fillable fields based on the appearance of the document. You can edit these fields and add new ones as needed.
