You can create a fillable form in Word itself that other people can fill out using Word. You must have the "Developer" tab visible in Word. To show it, click the "File" tab, then click "Options" and "Customize Ribbon." Under "Main tabs," select "Developer" and click "OK."
Then, create a new document. If you want to use an existing Word form template, you can use the "Search online templates" option in the Word New Document menu to find one that fits your needs.
Once the document is created, use the options on the Developer tab to add form fields in Word. For example, you can insert a "Rich Text Content Control" for people to enter text or create drop-down menus and check boxes. Add text to the form as well to tell people what to enter where.
After the form is created as you want, protect it from other people editing it by selecting all the form elements and text, clicking "Restrict Editing" in the Developer tab. Then click "Yes, Start Enforcing Restrictions." Email or otherwise distribute the form to its recipients to fill out, and then have them send it back to you.
Launch Microsoft Word 2010 or higher and open your existing Word document that you would like to turn into a fillable PDF form. If you do not have an existing document then click "File" and then "New" to create a new form.
Show the developer tap in Word by clicking "File" then "Options" then "Customize Ribbon." Click the "Developer" tab to enable it and then click "OK."
Add a combo box or drop-down list for any field that should be multiple choice. Click the "Developer" tab and then click "Combo Box Content Control" or "Drop-Down List Content Control" to add it to your form. Click the "Properties" option under the "Developer" tab to customize the options for your combo box or drop-down.
Add a check box for any field on your form that should be checked. Click the "Check Box Content Control" option under the "Developer" tab to add the check box next to a text field.
Save your Word document as a PDF by clicking "File" and then "Save" and then selecting "PDF." A fillable PDF form is then saved to your Documents folder.
