A fillable PDF form is a document with interactive fields that people can type into, tick and select from. To make one, start with a clear, well-designed document, add the fields on top of it, and test it on different devices before you send it out.
Asking people to print a form, fill it in by hand, sign it and scan it back is slow — and the result is often hard to read. A fillable PDF form lets them type their answers straight into the document, tick boxes, choose options from lists and send it back in minutes.
This guide explains what fillable forms are, the different types of fields, how to create one, and the details that make the difference between a form people like and one they abandon.
What is a fillable PDF form?
A fillable PDF is a normal PDF with interactive fields placed on top of the page. The page shows the design — labels, boxes, logo — and the fields capture what people type or select. Recipients can open it in a free PDF viewer or their browser, fill it in, save it and send it back.
What kinds of fields can a PDF form have?
| Field type | Best for |
|---|---|
| Text field | Names, addresses, short answers |
| Multi-line text | Comments and longer answers |
| Checkbox | Yes/no choices and agreements |
| Radio buttons | Choosing one option from a few |
| Drop-down list | Choosing from a longer list, like countries |
| Date field | Dates in a consistent format |
| Signature field | Signing the form electronically |
| Button | Printing, resetting or submitting the form |
How do I create a fillable PDF form?
Option 1: A professional PDF editor
Professional PDF applications (such as Adobe Acrobat Pro) have a form-preparation mode that can detect form fields automatically in an existing document. You then adjust each field, add any that were missed, set field names and save. This is the quickest route if you create forms regularly.
Option 2: LibreOffice Writer (free)
LibreOffice is free and can create fillable PDFs:
- Design your form in LibreOffice Writer.
- Turn on the Form Controls toolbar (View → Toolbars → Form Controls).
- Insert text boxes, checkboxes and list boxes where people should answer.
- Choose File → Export as PDF and make sure Create PDF form is ticked.
It takes more manual work, but it costs nothing.
Option 3: Ask an expert
If the form is important — for clients, staff or customers — a professionally built form saves time and avoids mistakes. Our PDF experts can turn any document into a reliable fillable form.
Tips for forms people actually complete
- Design first, fields second. A clear layout with obvious labels makes the form easy to understand before anyone types a word.
- Use the right field for the job. Checkboxes for yes/no, drop-downs for long lists, date fields for dates.
- Make text fields big enough for real answers — long names and addresses included.
- Set a sensible tab order so pressing Tab moves through the fields in reading order.
- Name fields clearly (for example
first_name,email) — it helps if you collect the data later. - Add tooltips to explain fields and to help people who use screen readers.
- Mark required fields so people know what they must complete.
- Test on several devices — computer, phone and different PDF apps — before you send it out.
Should forms be accessible?
Yes. Accessible forms have clear labels, tooltips and a logical order that screen readers can follow. In many countries, public bodies and large organisations are required to provide accessible documents, and it's good practice for everyone. Accessibility tagging is one of the services our experts offer.
What about sending the completed form back?
The simplest approach is to ask people to save the completed PDF and email it back. If you collect many forms, consider combining them for your records with Merge PDF, and keep only the pages you need with Split PDF.
