# Generate a PDF with a PDF form using JavaScript

With Nutrient, you can generate PDF files from a PDF form.

### Filling PDF form fields  programmatically using JavaScript

Nutrient Web SDK offers multiple options for filling form fields programmatically, each with a different set of tradeoffs.

- With Document Engine — For persisting, restoring, and synchronizing the form field values across multiple devices without needing to build it yourself.

- XFDF — For exporting to or importing from other readers.

- Instant JSON — For the most efficient way to export or import changes made.

- Manual API — For full control over extracting and saving the values of forms.

For more information on filling PDF form fields programmatically, see [our guide](https://www.nutrient.io/guides/web/forms/form-filling.md).

### Flattening form fields  using JavaScript

The process of flattening form fields consists of rendering them over the background of a page with their current value and removing their data from the document.

For more information on flattening form fields, see [our guide](https://www.nutrient.io/guides/web/forms/flatten.md).
