  • No sign-up, no watermark, no file limit

Create a fillable PDF form for free: open any PDF here, pick a field type — text box, checkbox, radio buttons or dropdown — click where it should go, set its name and options, and download. The fields are real AcroForm fields, the PDF standard, so people can fill them in Adobe Acrobat Reader and most PDF viewers, and you don't need Adobe Acrobat to make them. It runs in your browser, so the PDF is never uploaded, and there is no sign-up or limit. There are no signature or date fields; to sign a PDF, use Sign PDF.

How it works

How to Create a PDF Form in 3 Steps

Three steps. Open the PDF, click to place fields, download. The output is a real AcroForm — not a flattened image.

  1. Step 1: Open Your PDF

    Drop your PDF into the tool or click to browse your files. The PDF renders immediately inside your browser. No file is sent to any server during this step or at any point in the process. Open a blank PDF, an existing document, or any scanned form you want to make interactive.

  2. Step 2: Add Your Form Fields

    Click anywhere on the PDF to place a field. Choose the field type from the panel: text input, checkbox, radio button, or dropdown. In the field properties panel, set the field name (radio buttons: a group name and option value) and mark it as required. For a text field you can pre-fill a starting value, choose the font size (8–24 pt), make it multi-line and set a maximum character length; for a dropdown, list its options; radio buttons are grouped by name. Each field type appears in its own colour (blue, violet, pink, amber) so you can see your form layout at a glance.

  3. Step 3: Download Your Form

    Click Download to save your completed PDF form to your device. The output file contains real, native AcroForm fields — not images or overlays. Anyone who opens the file in Adobe Reader, a browser PDF viewer, or any standard PDF application can fill it in using standard form controls. No account, no subscription, and no usage limit apply at any step.

A real PDF form builder, not a workaround

Everything you need to build fillable PDFs

Every field you place becomes a genuine, interactive AcroForm element — the same format Adobe Acrobat uses. No locked PDFs, no flattened images, no workarounds.

Click to Place

Click anywhere on any page to drop a form field exactly where you want it. No grid snapping, no alignment guides needed. Position is pixel-precise.

Drag & Resize

Move any field by dragging it. Pull from the corner handle to resize. Adjust until it sits perfectly over your form layout.

4 Field Types

Text inputs (single-line and multi-line), checkboxes, radio buttons, and dropdowns. The four types cover every interactive element in standard PDF forms.

Field Properties

Set a name (for data mapping) and mark fields as required. Pre-fill a text field with a starting value the person filling it can keep or change, choose its font size (8–24 pt), make it multi-line or cap its length; add dropdown options and radio groups.

Color-Coded Overlays

Each field type renders in its own colour: blue for text inputs, violet for checkboxes, pink for dropdowns, amber for radio buttons. Spot your form structure at a glance before you download.

Real AcroForm Output

The downloaded PDF contains native AcroForm fields — the same format Adobe Acrobat, Microsoft Edge, Chrome, Safari, and most PDF readers can interact with natively. Not images. Not overlays. Real form fields.

What You Can Build with This Tool

The OneClickPDF form builder covers the full range of use cases where someone needs to add interactive fields to a PDF. The most common:

  • Internal business forms. Turn static HR documents, expense report templates, purchase order PDFs, and employee onboarding paperwork into fillable forms anyone on the team can complete digitally.
  • Client-facing documents. Add form fields to proposals, service agreements, intake questionnaires, and feedback forms that you send to clients, so they can fill them in without printing.
  • Education and training. Convert student enrolment applications, course registration sheets, consent forms, and assessment documents into interactive PDFs that participants submit digitally.
  • Healthcare admin. Build patient intake forms, HIPAA consent documents, health history questionnaires, and insurance pre-authorisation requests from existing PDF templates.
  • Legal and compliance. Add text fields for names and dates, required checkboxes and dropdowns to NDAs, lease agreements, contractor agreements, and compliance declarations.
  • Government and civic processes. Turn permit applications, committee submissions, public consultation forms, and grant applications into fillable PDFs for digital distribution.
  • Event registration. Create registration forms with dropdown options for ticket types, radio buttons for meal preferences, and text fields for attendee details, all within the same branded PDF.
  • Research and surveys. Build structured data collection forms where respondents fill fields directly in the PDF and return the completed file, with all responses in named, machine-readable fields.

How we compare

Why OneClickPDF beats every other free option

Most free PDF form builders either upload your file to a remote server, produce flattened images that look like form fields but can't be filled in a PDF reader, or lock their best features behind a paywall. OneClickPDF does none of those things.

Frequently Asked Questions

How do I create a fillable PDF form online for free?
Open your PDF on this page, pick a field type (text, checkbox, radio button or dropdown), click where the field should go and set its name and options; repeat for each field, then click Download. The result is a fillable AcroForm PDF, made free in your browser with no account.
Can I create a fillable PDF form without Adobe Acrobat?
Yes. OneClickPDF adds the form fields in your browser, with no Adobe Acrobat or other software to install. The downloaded PDF can then be filled in with Adobe Acrobat Reader or most other PDF viewers.
What types of form fields can I add to a PDF?
Four: text fields (single-line or multi-line, with an optional maximum length, font size of 8–24 pt and pre-filled text), checkboxes, radio buttons grouped by name, and dropdown lists with your own options and a default.
Can I add signature or date fields to a PDF form?
No. The tool makes text, checkbox, radio button and dropdown fields only; a text field can be used for a date typed by hand. To sign a PDF yourself, use Sign PDF.
Is it free to create a PDF form online?
Yes, the form builder is free, with no account, no watermark and no limit on the number of forms or fields. It is free for personal and commercial use.
Will the form fields I create work in Adobe Reader and other PDF viewers?
Yes. Each field is a native AcroForm field, the interactive form format defined in the PDF standard, which Adobe Acrobat Reader and most PDF viewers on desktop and mobile can fill in. Recipients don't need any special software or plugin.
Can I edit the form later or add more fields?
You can open the PDF here again and place more fields; the fields already in it are kept, and new fields get names that don't clash with them. The tool doesn't move or edit fields that are already in the file.
Can I create a PDF form on my phone?
Yes. On a phone the field panel slides in from the side, and you tap the page to place a field, then download the form to your device.
How do I make a required field in a PDF form?
Select the field and tick Required in its properties panel. Text fields, checkboxes and dropdowns get the PDF's Required flag, and radio buttons are required as a group: tick Required on any button in the group. Acrobat and other viewers that support the flag outline required fields in red. The flag is enforced only when a form is sent with a Submit button, which this tool doesn't add, so recipients can still save, print or email a form with required fields left empty.
Can I create a fillable PDF form from an existing Word or Excel document?
Yes, export your Word document or Excel spreadsheet to PDF using the built-in export functions in Microsoft Office (File > Export > PDF) or Google Docs (File > Download > PDF). Then open that PDF in the OneClickPDF form builder and add form fields on top. The layout, text, and formatting from the original document are preserved, and you add interactive fields exactly where you need them.
What is an AcroForm PDF?
An AcroForm PDF is a PDF file that contains native, interactive form fields defined in the PDF specification and originally developed by Adobe. AcroForm fields are the standard format used by IRS tax documents, government applications, legal contracts, and most professional PDF forms in circulation. Unlike flat PDFs (which are just images of forms), AcroForm PDFs can be filled in, submitted, and data-extracted by PDF reader software and automated systems.
Is it safe to build a PDF form using an online tool?
With OneClickPDF, yes. The entire form-building process runs inside your browser using client-side JavaScript. Your PDF is never uploaded to a server, never stored in the cloud, and never processed on any external infrastructure. This means confidential templates, proprietary document layouts, and sensitive form structures stay entirely on your device from the moment you open the tool to the moment you download the finished file.
How do I group radio buttons so only one can be selected at a time?
In the field properties panel for each radio button, set the same Group Name for all buttons that should belong to the same question. When the finished PDF is opened in a PDF reader, selecting one radio button in the group automatically deselects the others. This is the standard AcroForm radio group behaviour. Buttons with different group names behave as separate, independent questions.
