Forms & Fillable

How to Make a Fillable PDF in Word (Free, Built-In)

The short answer

Make a fillable PDF in Word with the Developer tab: add form fields (text boxes, checkboxes, dropdowns), then export to PDF — the fields survive the export and people can type into them. It’s the closest thing to a free fillable-form maker, and it’s already on your computer.

Turn on the Developer tab

  1. In Word, go to File → Options → Customize Ribbon.
  2. On the right side, check Developer.
  3. Click OK — a new Developer tab appears in the ribbon.

One-time setup, and it’s where all the form tools live. (The full fillable-PDF picture is in how to create a fillable PDF — this is the Word-specific version.)

Add form fields

  1. On the Developer tab, find the Controls group: Legacy Tools (the toolbox icon) has the classic fields — Text Form Field, Check Box, Drop-Down.
  2. Click where each field goes and insert it: a text box for answers, a checkbox for yes/no, a dropdown for choices.
  3. Set field properties (right-click → Properties): default text, dropdown options, max length.
  4. Optionally protect the form (Restrict Editing → Filling in forms) so users only touch the fields.

Keep it simple: for most forms, text boxes plus checkboxes are 90% of the job.

Export to a fillable PDF

  1. File → Save As → PDF.
  2. Save, open the PDF, and test: click a field — can you type into it?
  3. If yes, done. If the fields are dead, check they were inserted with the Developer tab tools (not typed characters), and re-export.

The honest gotcha: Word’s PDF export preserves fields made with the legacy controls, but not every field type exports cleanly — dropdowns and dates sometimes arrive as plain text. Test before sending.

The honest part

Two limits worth knowing: (1) Word forms are fine for simple questionnaires, and clunky for complex ones — if you need validation, calculations, or signatures, a proper form tool is better. (2) The fillable fields need a real PDF reader — tell recipients to open it in Acrobat Reader (free) if fields don’t respond in a browser viewer. And if you’re starting from an existing PDF rather than a Word doc, see converting a PDF to a fillable form instead.
