Why Fillable PDFs Matter
A fillable PDF lets recipients type directly into form fields instead of printing, handwriting, and scanning. This saves time, reduces errors, and produces legible, professional documents. Application forms, client intake sheets, contracts, surveys, and order forms all benefit from fillable fields.
The problem: Adobe Acrobat Pro — the traditional tool for creating fillable PDFs — costs $12.99/month. Most free PDF editors can add text on top of a PDF but cannot create true interactive form fields that recipients can tab through and fill in.
MiOffice's free PDF editor lets you add real form fields to any PDF. Everything runs in your browser — no account, no upload, no watermark.
How to Create a Fillable PDF (5 Steps)
Open the PDF Editor
Navigate to the MiOffice PDF editor. Guest access on supported tools; AI requires sign-in and credits or download needed. The editor loads directly in your browser.
Upload Your PDF
Drag and drop your existing PDF or click to browse. This can be a blank form template, a scanned document, or any PDF you want to make interactive. The file stays on your device.
Add Text Input Fields
Select the text field tool from the form toolbar. Click where you want a field to appear, then drag to set its size. Add field labels and placeholder text. Repeat for every text input area — name, email, address, phone, etc.
Add Checkboxes, Dropdowns, and Signature Fields
Use the checkbox tool for yes/no questions and terms acceptance. Add dropdown menus for predefined selections like country, department, or service tier. Place signature fields where you need the recipient to sign.
Save the Fillable PDF
Download your fillable PDF. The form fields are embedded in the PDF standard format and will work in Adobe Reader, Chrome, Preview, and most modern PDF viewers. Share via email, cloud storage, or your website.

Text Input Field
The most common form field. Use for names, addresses, email addresses, phone numbers, and any free-text response. Can be single-line (name, email) or multi-line (comments, descriptions). Set placeholder text to guide respondents.
Checkbox
Used for yes/no questions, terms and conditions acceptance, and multi-select options. Each checkbox is independent — the recipient can check or uncheck it. Use multiple checkboxes when the respondent can select more than one option.
Radio Button
Used for single-selection from a group of options. Unlike checkboxes, only one radio button in a group can be selected at a time. Use for questions like “Select your preferred contact method: Phone / Email / Mail.”
Dropdown Menu
Presents a list of predefined options in a compact format. Ideal when there are many choices (country, state, department, service level). Saves space compared to radio buttons and reduces typos since recipients select from fixed options.
Signature Field
A designated area for electronic signatures. Recipients can draw, type, or upload their signature. Essential for contracts, agreements, consent forms, and any document requiring formal acknowledgment. See our guide on how to eSign a PDF for details on legal validity.
Use Cases for Fillable PDFs
Application Forms
Job applications, membership forms, enrollment documents. Structure with text fields for personal information, dropdowns for selections, and a signature field for confirmation.
Surveys and Feedback
Customer satisfaction forms, course evaluations, event feedback. Use radio buttons for rating scales, checkboxes for multi-select, and text areas for open comments.
Contracts and Agreements
Freelance contracts, rental agreements, NDAs. Pre-fill your company details, leave fields for the other party to complete, and add signature fields at the bottom.
Order Forms
Product orders, service requests, catering forms. Use dropdowns for product selection, text fields for quantities and delivery details, and checkboxes for add-on options.
Comparison: Fillable PDF Creators
| Feature | MiOffice | Adobe Acrobat | JotForm | Google Forms |
|---|---|---|---|---|
| Cost | Free | $12.99/mo | Free tier / $34/mo | Free |
| PDF output | Yes (native) | Yes (native) | PDF export | No native PDF |
| Works offline | Yes (PWA) | Desktop: Yes | No | No |

Key takeaway: Google Forms and JotForm are great for collecting responses via web forms, but they do not produce native fillable PDFs. Adobe Acrobat Pro is the gold standard for complex PDF forms but costs $156/year. MiOffice fills the gap — a free, browser-based tool that creates real fillable PDF documents.
Tips for Better Fillable PDFs
Label every field clearly. Place labels above or to the left of each field. Avoid putting labels inside the field as placeholder text only — they disappear when the user starts typing.
Use tab order. Arrange fields in a logical reading order (top to bottom, left to right) so users can tab through the form without jumping around the page.
Group related fields. Keep personal information together, payment details together, and signature/date at the bottom. Use visual separators or section headers to organize long forms.
Test before distributing. Fill out your own form to check that fields are sized correctly, dropdowns contain all options, and the overall flow makes sense.
