How to Create Fillable PDF: Complete Guide

You need a form that clients can fill out electronically – an application, an order form, a feedback survey, or a tax document. Instead of printing and scanning, you can create a fillable PDF with text fields, checkboxes, radio buttons, dropdown lists, and signature fields. This guide covers every method: from simple online tools (no installation) to professional software (Adobe Acrobat Pro), free desktop alternatives (LibreOffice, PDF‑XChange Editor), and even using Microsoft Word or Google Docs as starting points. By the end, you will be able to create interactive, fillable PDFs that anyone can complete on any device.

What Is a Fillable PDF?

A fillable PDF (also called an interactive PDF form) contains form fields that users can click, type into, select, or sign without printing. The fields can be:

  • Text fields: For names, addresses, comments.
  • Checkboxes: For yes/no or multiple selections.
  • Radio buttons: For exclusive choices (only one selectable).
  • Dropdown/combo boxes: For selecting from a list.
  • List boxes: For multi‑select lists.
  • Button fields: For resetting or submitting forms.
  • Signature fields: For digital or electronic signatures.

Fillable PDFs can be saved, emailed, and opened in free Adobe Acrobat Reader, browsers, and mobile PDF apps.

Method 1: Create Fillable PDF Using Online Tools (Fastest)

Online form creators are ideal for quick, simple forms (5‑20 fields) that do not contain sensitive data. Avoid uploading confidential forms.

Using Our Create Fillable PDF Tool (Coming Soon):

We are developing a dedicated fillable PDF creator. In the meantime, use these alternatives.

Alternative Free Online Form Creators:

  • Jotform PDF Editor: Drag‑and‑drop fields, export as fillable PDF. Free tier with watermark.
  • PDFescape (online version): Upload PDF, and use "Form Field" tools to add text, checkboxes, radio buttons, etc. Free with 10 MB limit.
  • Sejda Form Editor: Upload PDF, add fields, save as fillable PDF. Free tier: 50 MB, 200 pages, 3 tasks/hour.
  • SmallPDF Form Creator: Free trial, then paid.

Workflow using PDFescape:

  1. Go to PDFescape online.
  2. Upload your PDF (or start with a blank page).
  3. Click "Form Field" tools: Text, Checkbox, Radio, Dropdown, Button.
  4. Place fields on the document. Double‑click to edit properties (field name, default value, required, etc.).
  5. Click "Save" and download the fillable PDF.

Method 2: Create Fillable PDF Using Adobe Acrobat Pro (Professional, Most Powerful)

Adobe Acrobat Pro is the industry standard for form creation. It automatically detects static form fields and lets you add, edit, and manage them with precision.

  1. Open your PDF (or a scanned document) in Adobe Acrobat Pro.
  2. Go to Tools > Prepare Form. Acrobat will automatically detect and create fillable fields based on the document (underlines, brackets, lines, etc.).
  3. Review the auto‑generated fields. Delete or adjust as needed.
  4. To add more fields, click the toolbar: Text Field, Checkbox, Radio Button, Dropdown, List Box, Button, Signature Field.
  5. Click on the document where you want the field. Adjust size and position.
  6. Edit field properties: Double‑click a field. Set:
    • Name: The internal identifier (e.g., "FullName").
    • Tooltip: Help text that appears when hovering.
    • Default value: Pre‑filled text.
    • Required: Force user to fill.
    • Multiline: For text areas.
    • Options (for dropdown/radio): Add choices.
  7. Click More to set formatting (date, number, calculations).
  8. After adding all fields, click Close Form Editing.
  9. Save the PDF. It is now fillable. Test by opening in Adobe Reader.

Method 3: Create Fillable PDF Using Microsoft Word (Free, Simple)

If you have Word, you can create a form and save as fillable PDF – but Word's PDF form fields have limited functionality.

  1. Create your document in Word. Leave placeholder text (e.g., "__________" for text, [ ] for checkboxes).
  2. Go to File > Options > Customize Ribbon > Enable "Developer" tab.
  3. In the Developer tab, use controls:
    • Rich Text Content Control / Plain Text Content Control: For text input.
    • Checkbox Content Control: For yes/no.
    • Combo Box / Dropdown List Content Control: For selections.
    • Date Picker Content Control: For dates.
  4. Design your form with these controls.
  5. Go to File > Save As > choose PDF. Click Options... and check "Create bookmarks using headings" and "Document structure tags for accessibility".
  6. Save. The resulting PDF will have fillable fields based on the Word content controls.

Limitation: Word exports only basic fields; complex formatting may break. For advanced forms, use Acrobat Pro.

Method 4: Create Fillable PDF Using Free Desktop Software (Offline)

These tools are free, offline, and do not require uploading.

LibreOffice Draw (Free, Cross‑platform):

  1. Open your PDF or create a new document in LibreOffice Draw.
  2. Go to View > Toolbars > Form Controls.
  3. Click the form controls icons (Text Box, Check Box, Option Button (radio), List Box, Combo Box, Push Button).
  4. Draw the field on the document.
  5. Right‑click the field > Control to set properties:
    • Name: Identifier.
    • Label: Visible text (for buttons/checkboxes).
    • List entries: For dropdowns (separated by semicolon).
  6. When done, go to File > Export As > Export as PDF.
  7. In the PDF options, ensure "Form Fields" is checked.
  8. Export. The PDF will be fillable.

PDF‑XChange Editor (Free version, Windows):

  1. Open the PDF in PDF‑XChange Editor.
  2. Go to Form > Add > choose field type (Text, Checkbox, Radio, Dropdown, List, Button, Signature).
  3. Click on the document to place the field. Drag to resize.
  4. Double‑click the field to set properties (name, default, options).
  5. After adding all fields, save the PDF. The free version adds a small watermark, but forms remain fillable.

Step‑by‑Step Workflow to Create a Fillable PDF

  1. Design your form layout in Word, Google Docs, or any editor. Place lines or brackets where fields will go.
  2. Convert to PDF (if needed) using our Word to PDF tool.
  3. Open the PDF in a form creation tool (Adobe Acrobat Pro, PDFescape, or PDF‑XChange).
  4. Add form fields: text fields, checkboxes, radio buttons, dropdowns, signature fields.
  5. Configure field properties: names, tooltips, default values, required, formatting, calculation.
  6. Test the form: Open in Adobe Reader, fill it out, save a completed copy.
  7. Distribute: Email the fillable PDF or post it for download. Remind users to open in Adobe Reader (browsers may not support all field types).

Best Practices for Fillable PDFs

  • Use clear labels: Each field should have a visible label (e.g., "Full Name: " next to the text field).
  • Set tab order: In Acrobat Pro, use "Order" panel to set the sequence when users press Tab.
  • Mark required fields: Use asterisk (*) or a note.
  • Provide instructions: Add a brief note on how to fill and save.
  • Avoid overly complex layouts: Too many fields on one page can be overwhelming.
  • Test on multiple devices: Open the PDF on a mobile phone (Adobe Reader app) to ensure fields are accessible.
  • Flatten the PDF after collecting responses? No – keep fields editable for data entry, you can later flatten a copy for archiving.

Common Mistakes When Creating Fillable PDFs

  • Using browser preview instead of Adobe Reader: Many browsers display PDFs but do not support editing form fields. Inform users to download and open in Adobe Acrobat Reader.
  • Not setting tab order: Users tab randomly across the page.
  • Forgetting to save as fillable PDF: After adding fields, you must save the file; some tools export a non‑interactive PDF by default.
  • Making radio buttons ungrouped: Radio buttons that are not in the same group allow multiple selections – use the same field name for grouped radios.
  • Using signature fields that require a paid certificate: For basic electronic signatures, use a "Signature" field that allows typed/drawn signatures, not a digital ID.
  • Large file size after adding fields: Use Compress PDF to reduce size without breaking fields.

Tools for PDF Management – DonePDF Utilities

  • Compress PDF – Reduce fillable PDF size without breaking form fields.
  • PDF to Word – Convert fillable PDF to editable Word (fields may become plain text).
  • Merge PDF – Combine multiple fillable forms.
  • Split PDF – Extract specific pages from a form.
  • Protect PDF – Add password to prevent unauthorized editing of form fields.

Frequently Asked Questions

How can I create a fillable PDF for free?

You can create a fillable PDF for free using several methods:

  1. Online (easiest): Use PDFescape (free tier, 10 MB limit) or Sejda Form Editor (50 MB, 200 pages, 3 tasks/hour). Upload your PDF, add text fields, checkboxes, radio buttons, dropdowns, then download the fillable PDF.
  2. Offline (Windows): PDF‑XChange Editor free version – open PDF, go to Form > Add > select field type. The free version adds a small watermark but form works.
  3. Offline (cross‑platform): LibreOffice Draw – enable Form Controls toolbar, add fields, export as PDF with "Form Fields" option.

For sensitive forms, use offline methods. For quick, non‑confidential forms, online tools are convenient.

What types of fields can I add to a fillable PDF?

You can add these interactive form fields:

  • Text field: For single‑line or multi‑line text (names, addresses, comments).
  • Checkbox: For yes/no or multiple independent selections.
  • Radio button: For exclusive choices (only one in a group can be selected).
  • Dropdown (combo box): User selects from a menu; can also allow typing.
  • List box: Shows several options at once, allows multi‑select.
  • Button: For resetting form, submitting data (requires scripting).
  • Signature field: For electronic signatures (typed, drawn, or uploaded image).
  • Date picker: For calendar selection (in Adobe Acrobat Pro).
  • Barcode field: For generating barcodes (professional tools).

Most free tools support text, checkbox, radio, and dropdown. Adobe Acrobat Pro supports all types plus calculations and JavaScript.

Can I create a fillable PDF from a scanned document?

Yes, but you first need to convert the scanned image into a PDF (if not already). Then you can add fillable fields on top of the scanned image. However, the underlying text is an image, so users cannot edit the static text – only fill the fields. To make the static text searchable and selectable, run OCR first using our OCR PDF tool, then add form fields. The process:

  1. Scan the document as PDF (300 DPI).
  2. Apply OCR to create a searchable PDF (optional).
  3. Open the PDF in a form editor (Adobe Acrobat Pro, PDFescape, Sejda).
  4. Add form fields over the scanned image.
  5. Save as fillable PDF.

Note: The scanned background may increase file size – compress after adding fields.

How do I make a PDF fillable in Adobe Acrobat Reader for free?

Adobe Acrobat Reader (free) can fill existing fillable PDFs, but it cannot create fillable fields. To create fields, you need the paid Adobe Acrobat Pro. However, you can use these free alternatives:

  • PDFescape (online): Upload PDF, add fields, download fillable PDF – no Acrobat needed.
  • Sejda Form Editor (online): Similar, free tier with limits.
  • LibreOffice Draw (free desktop): Add form controls and export as fillable PDF.

After creating the fillable PDF with these free tools, users can open it in Adobe Acrobat Reader and fill it without any cost.

What is the best tool to create fillable PDFs?

The best tool depends on your needs:

  • For quick, simple forms (non‑sensitive): Sejda or PDFescape (free online).
  • For professional, complex forms (calculations, validation, signatures): Adobe Acrobat Pro (~$15/month).
  • For free offline form creation on Windows: PDF‑XChange Editor (free, adds small watermark).
  • For free cross‑platform (Windows/Mac/Linux): LibreOffice Draw (no watermark, but interface less intuitive).
  • If you already have Microsoft Word: Use Word's Developer controls then export to PDF – limited but works for basic forms.

For most users, Sejda or PDFescape will be sufficient.

How do I add a signature field to a fillable PDF?

To add a signature field (for electronic signatures, not digital certificates):

  1. Adobe Acrobat Pro: In Prepare Form mode, select "Signature Field" from the toolbar, click on the document. Users can later click to sign by typing, drawing, or uploading signature image.
  2. PDF‑XChange Editor: Form > Add > Signature Field. Place on document.
  3. LibreOffice Draw: Insert a "Push Button" and label it "Sign Here". However, it does not natively support signature fields; users would need to add a signature manually.
  4. Online tools (PDFescape, Sejda): Most do not support signature fields; you can use a text field as a placeholder and instruct users to add their signature via external tool.

For legally binding digital signatures (certificate‑based), you need Adobe Acrobat Pro or a dedicated e‑sign platform like DocuSign.

Why is my fillable PDF not working in a web browser?

Most web browsers (Chrome, Edge, Safari) have built‑in PDF viewers that only display the document – they do not support interactive form fields, JavaScript, or signature fields. To fill a fillable PDF, users should:

  1. Download the PDF to their computer.
  2. Open it in Adobe Acrobat Reader (free) or other PDF reader that supports forms (Foxit, PDF‑XChange Editor).
  3. Fill the fields and save.

To remind users, include a note in the PDF: "Please open this form in Adobe Acrobat Reader to fill and save." Alternatively, use online form builders (Google Forms, Jotform) that work in browsers.

How do I make radio buttons work correctly in a fillable PDF?

Radio buttons must be grouped so that only one can be selected at a time. In Adobe Acrobat Pro:

  1. Add your radio buttons.
  2. Double‑click a radio button> Options tab.
  3. Give all radio buttons in the same group the same field name (e.g., "Gender").
  4. Set a different export value for each button (e.g., "Male", "Female").

In PDFescape: After adding radio buttons, use the "Group" option or ensure the "Radio group name" is identical. In LibreOffice Draw: Right‑click a radio button > Control > set "Name" same for all in group, and "Value" different.

If you do not group them, users will be able to select all radio buttons simultaneously – incorrect.

Can I create a fillable PDF on my phone or tablet?

Yes, but with limitations. Mobile apps are generally for filling forms, not creating them. However, these apps allow basic form creation:

  • Adobe Acrobat Pro (iPad): Paid, supports creating fillable fields (text boxes, checkboxes, signatures).
  • PDFescape (mobile browser): The online editor works on mobile browsers, but the interface is cramped.
  • Microsoft Word (iOS/Android): Create a document with content controls (Developer tab not available on mobile; use table with placeholders), then save as PDF – limited.

For serious form creation, use a desktop computer. For simple forms, consider Google Forms instead of PDFs.
