How to Create a Fillable PDF (So People Can Type Into It)
The short answer
The fastest way to create a fillable PDF is to build the form in Word or Google Docs and export it as a PDF — Word’s form fields survive the export, and Google Docs adds them automatically. If you’re starting from an existing paper form, you’ll need a PDF editor to add the fields yourself.
Create a fillable PDF in Word
- In Word, turn on the Developer tab (File → Options → Customize Ribbon → check Developer).
- Add form fields from the Developer tab: text boxes, checkboxes, dropdowns.
- Save the file — Word keeps the fields when you export to PDF via File → Save As → PDF.
This is the closest thing to free: if you own Word, the fillable PDF costs nothing extra, and your users can type straight into the fields in any PDF reader.
Create a fillable PDF in Google Docs
Google Docs has no true form fields, but it does something clever: build a simple questionnaire — question, blank line, checkbox character — and when you export to PDF, Google turns the checkboxes into clickable ones. For basic forms that’s genuinely enough, and it’s free. Real dropdowns and date pickers? You’ll want a proper tool.
Make an existing scanned form fillable
This is the common painful case: you have a paper application form, scanned to PDF, and you need people to type into it. The scanner output is just an image, so you need a PDF editor to drop text fields on top:
- Adobe Acrobat Pro does this well (paid).
- Online form builders — upload the scanned PDF, click where fields should go, save.
- Our PDF tools cover the basics like scanning and converting, and a dedicated form tool for the field-dropping part.
Honest note: dropping fields on a scanned image works, but the fields won’t auto-align with the printed lines — you’ll spend ten minutes nudging them into place. That’s normal, not a bug.
The honest part
Creating a fillable PDF is easy when you control the source (Word/Google), fiddly when you don’t (scanned paper). And here’s the part people learn the hard way: fillable fields only work in a real PDF reader. If someone opens your form in a browser’s built-in viewer and the fields don’t respond, the tool is the problem, not the file — tell them to open it in Acrobat Reader, which is free.
