How to make a PDF fillable in Adobe

Adobe Acrobat can be used to create fillable PDFs from scratch or convert existing files into fillable PDFs. To make a fillable PDF, one needs to first create the form in Microsoft Word or Google Docs with placeholders for user input, and then export it as a PDF. Adobe Acrobat is then used to add fillable form fields, edit field properties, and customize the form. The free version of Adobe Acrobat has limitations, but other PDF editor apps like PDF.co offer similar functionality at no cost.
