A paperless office starts with filling out a PDF form on the go and emailing it back within the minute.
PDFs are great because they’re typically universal - pretty much anyone can open and view them. They are convenient and can be viewed on almost any type of device.
The only disadvantage PDF documents can have is that they’re uneditable and it can be difficult to modify them.
If you need to sign or fill in a form on a PDF that is already fillable (or not), there are a few different ways you can do this.
Below we’ll cover a few different options if you’re looking for ways to fill out a PDF form and email it with software such as Adobe Acrobat, online services, and more. And we'll also cover how to fill out a PDF form that is not fillable.

- How to Check If Your PDF Document Is Fillable Onscreen With Adobe Acrobat
- How to Fill Out a PDF Form And Email It (Online and Offline)
- How to Fill In Interactive PDF Forms
- How To Convert A PDF File To A Fillable Form
But first, you’ll need to check and see if your PDF is already fillable.
How to Check If Your PDF Document Is Fillable Onscreen With Adobe Acrobat
To determine if your PDF is already fillable, you can use Adobe Acrobat.
Follow these steps to find any interactive fields in your PDF document (if applicable):
1. Open the form in an Acrobat product.
2. Select the Hand tool, and then drag it over fields in the PDF form. The form contains form fields if the Hand tool changes to either of the following icons:
- An I-beam (the Text Select tool, which you use to type text in a text field
- A pointing hand (which you use to select an option or to check a box)
3. In Acrobat 3D, Acrobat 7, or Adobe Reader 7, click Highlight Fields or Highlight Required Fields in the Document Message Bar. Interactive fields display a colored fill.

Once you make any text or other changes to your document, you can always flatten the PDF file later.
