# Adding margins to PDF pages using JavaScript

It’s possible to individually add margins to multiple document pages using the `addPageMargins` document operation.

This feature is only available to customers who have purchased the Document Editor component. If you want to try it, [contact our Sales team](https://www.nutrient.io/contact-sales).

## How to add margins to pages using the programmatic API

You can use [`NutrientViewer.Instance#applyOperations`](https://www.nutrient.io/api/web/NutrientViewer.Instance.html#applyOperations) to add margins to PDF document pages:

```js

await instance.applyOperations([
  {
    type: "addPageMargins",
    pageIndexes: [1, 2],
    rect: new NutrientViewer.Geometry.Inset({
      left: 10,
      top: 10,
      right: 10,
      bottom: 10
    })
  }
]);

```

If you omit the `pageIndexes` property from the code above, all the PDF document’s pages will have their margins modified.
