How to Make a Fillable PDF in Word

Word cannot add fillable PDF fields by itself. The reliable route is to build the form layout in Word, choose File > Save As and pick PDF (*.pdf), then open that PDF in Adobe Acrobat and use Tools > Prepare Form to turn the blanks into fields people can type in.

Applies to: Word for Microsoft 365 on Windows, with notes for Word for Mac and Word for the web, plus Adobe Acrobat for the PDF fields. Checked against Microsoft Support and Adobe on October 7, 2026.

What Word can and cannot do

A fillable PDF contains form fields: boxes that a PDF reader recognizes as places to type, check or choose. Word has its own form fields, called content controls, but they belong to the Word file format. Microsoft’s instructions for saving as a PDF describe a file that keeps the layout and format of the document, and the save options do not include a setting for form fields. Adobe’s own instructions for this job have you save the Word file as a PDF first and then let Acrobat create the fields.

That leaves two honest choices:

• Fillable PDF: design in Word, add the fields in a PDF form tool. Pick this when people will fill in the form on different devices or without Word.
• Fillable Word form: add content controls and send the .docx file. Pick this when everyone who fills it in has Word. The steps are further down this page.

Before you start

• Word on a computer. The desktop app gives you the full set of PDF save options.
• Adobe Acrobat with the form tool for the field step. Adobe sells several Acrobat plans, so check on Adobe’s site that yours includes it.
• A list of the questions on your form and the kind of answer each one needs: a line of text, a date, a check box or a signature.

Make a fillable PDF from a Word document

1. Start the form in Word. Select File > New > Blank document. To start from a ready-made layout, type Forms in the template search box on the same screen, pick a template and select Create.
2. Type the labels and instructions. Add every question, heading and note the form needs. A table keeps labels and answer spaces lined up.
3. Mark each answer space with a line of underscores. Type a row of underscore characters after each label, for example Name: ____________. Adobe’s instructions say Acrobat uses these horizontal lines to work out where the fillable fields should go.
4. Save the Word file. Keep this .docx copy as your master. If the wording changes later, you edit this file and make a new PDF.
5. Save a PDF copy. Select File > Save As (or Save a Copy), open the file type list and choose PDF (*.pdf). To help people who use screen readers, select More options…, then Options, select the Document structure tags for accessibility check box and select OK before you save. You now have a PDF that looks like the form but cannot be typed in yet.
6. Open the PDF in Acrobat. Right-click the PDF file, choose Open With and pick Adobe Acrobat.
7. Create the fields. In Acrobat, select Tools > Prepare Form. Acrobat looks for the horizontal lines and creates a fillable field on each one. Check every field against its label, and add or remove fields where the detection missed something.
8. Save the fillable PDF. Select File > Save As and give the finished form its own name so you can tell it apart from the plain PDF.

Adobe documents these steps in its guide to creating a fillable PDF from a Word document. Acrobat’s layout differs between versions, so if you do not see a Tools menu, look for the form preparation tool in Acrobat’s list of tools.

Save the PDF from Word for Mac or Word for the web

Only the save step changes. The Acrobat steps stay the same.

Word for Mac

1. Select File, then Save As.
2. Select File Format at the bottom of the window and choose PDF.
3. Choose Best for electronic distribution and accessibility (uses Microsoft online service) so the PDF is tagged for accessibility.
4. Name the file and select Export.

Word for the web

1. Select File > Print > Print.
2. Under Printer, choose Save as PDF, then select Save.
3. Name the PDF, choose where to keep it and select Save.

Microsoft describes the result as a basic PDF that preserves the layout and format, and points to the desktop app for more control. The site’s guide to converting Word to PDF in Windows 10 covers the save options in more detail.

Alternative: make a fillable form that stays in Word

If the people filling in the form all use Word, you can skip the PDF and send a protected Word form. This uses the Developer tab, which is hidden by default.

1. Show the Developer tab. On the File tab, choose Options, then Customize Ribbon. In the list of main tabs, select the Developer check box and choose OK. A Developer tab appears on the ribbon.
2. Add a control for each answer. Click where the answer goes, then on the Developer tab pick a control from the Controls section.
3. Set the choices for lists. Select a combo box or drop-down list, select Properties, then select Add under Drop-Down List Properties and type each choice in Display Name.
4. Protect the form. Select Developer > Restrict Editing, choose the restrictions you want, then select Yes, Start Enforcing Protection. People can now fill in the controls without changing the rest of the document.

These are the controls Microsoft lists, and what each one is for:

Control	Use it for
Rich Text Content Control	Answers that may need formatting such as bold or italic, or more than one paragraph
Plain Text Content Control	Short answers with no formatting, such as a name or phone number
Check Box Content Control	Yes or no items and checklists
Drop-Down List Content Control	One answer from a fixed set of choices
Combo Box Content Control	A list of choices where people can also type their own answer
Date Picker Content Control	Dates chosen from a calendar
Picture Content Control	A photo or logo added by the person filling in the form

Microsoft’s page on creating forms that users complete or print in Word has the full list. Microsoft also notes that the boxes around content controls do not print, so a printed copy looks clean.

Check that the form works

1. Open the finished PDF in a PDF reader, not in Acrobat’s form editing view.
2. Click each answer space and type a sample answer. A working field accepts typing directly on the line.
3. Open the same file in a second app, such as a web browser, and repeat. In Windows, Microsoft Edge can fill in PDF form fields; see how to type on a PDF in Windows 10.
4. Save the filled-in copy, close it and open it again to confirm the answers were kept.

To change the form later, edit the Word master, save a new PDF and run the form tool again. To remove a control from a Word form, right-click it and select Remove content control.

Troubleshooting

The PDF opens but nothing can be typed in

The file is a plain PDF saved from Word. It still needs the field step in Acrobat. Saving from Word again will not change this, even if the Word file has content controls.

Acrobat missed some fields or put them in the wrong place

Detection depends on the horizontal lines. Go back to the Word master, give every answer space its own line of underscores with clear space around it, save a new PDF and prepare the form again.

The Developer tab is missing in Word

It is turned off by default. Turn it on with File > Options > Customize Ribbon and the Developer check box.

Nobody can pick an item from a drop-down list in the Word form

Open the control’s Properties and clear Contents cannot be edited. Microsoft notes that when this box is selected, people cannot select a choice.

Only part of the Word form should be locked

Split the document with section breaks, then use Select Sections in the Restrict Editing panel to protect only the sections you choose.

You cannot install Acrobat on a work or school computer

Software installs are often limited on managed computers. Ask your IT department which PDF form tool is approved, or send the protected Word form instead.

Frequently asked questions

Can Word make a fillable PDF without any other software?

No. Word saves a PDF that keeps the look of the page, but the fields are added afterward in a PDF form tool such as Adobe Acrobat.

Do Word content controls become PDF fields when I save as PDF?

Do not count on it. Microsoft’s save options do not mention form fields, and Adobe’s instructions create the fields in Acrobat from the lines on the page. Use underscores in the PDF version and keep content controls for forms that stay in Word.

How long does the conversion take?

Adobe says converting a Word document to a PDF normally takes a matter of seconds. Checking and correcting the fields is what takes the time, so allow a few minutes for a one-page form.

Should I send a fillable PDF or a Word form?

Send a PDF when the layout must stay fixed and you do not know what software people have. Send a Word form when everyone has Word and you want to skip the extra tool.

Is it safe to collect personal details with a fillable PDF?

The form itself is only a file. If it asks for sensitive information, agree on a secure way to return it rather than plain email attachments.

Next step: build a one-page test form with three or four questions, run it through the steps above and fill it in yourself before you send the real one.
