title: Create a Read-Only PDF Form
product: PDF Generator
description: This demo illustrates how to pre-fill a SurveyJS form with data and then generate a read-only PDF document using the PDF Generator. The JavaScript demo focuses on creating non-editable PDF forms for viewing purposes, rather than interactive forms for user input that are generated by default.

# Create a Read-Only PDF Form (Vue 3)

By default, PDF Generator renders SurveyJS forms as PDF files with interactive elements, allowing users to enter text in text boxes, select items from drop-down lists and radio button groups, and otherwise modify the generated forms. If your PDF form is intended only for viewing, you can enable read-only mode. This demo shows how to pre-fill a form with data and save it as a read-only PDF document.

To generate any PDF document using SurveyJS PDF Generator, you need to create a [`SurveyPDF`](/pdf-generator/documentation/api-reference/surveypdf) instance by passing a survey JSON schema and document configuration options as parameters to the `SurveyPDF` constructor:

```js
const surveyPdf = new SurveyPDF.SurveyPDF(surveyJson, pdfDocOptions);

// In modular applications:
import { SurveyPDF } from "survey-pdf";
const surveyPdf = new SurveyPDF(surveyJson, pdfDocOptions);
```

To pre-fill a PDF document with data, assign a JSON object with survey results to `SurveyPDF`'s `data` property. Enable the read-only mode by setting the `readOnly` property to `true` and call the [`save(fileName)`](/pdf-generator/documentation/api-reference/surveypdf#save) method to save the generated form on the user's computer:

```js
surveyPdf.data = surveyResults;
surveyPdf.readOnly = true;
```
