# Chart Image Export

This section shows how to export charts via the Chart Toolbar and Grid API.

## Export Charts via Chart Toolbar

Users can use the 'Download Chart' [Chart Menu](https://www.ag-grid.com/vue-data-grid/integrated-charts-menu/) item to download the rendered chart in the browser.

Note that the downloaded chart image will be in a `PNG` format.

## Export Charts via Grid API

There are two ways to download the chart image using the Grid API as shown below:

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `getChartImageDataURL` | `Function` |  |  | Returns a base64-encoded image data URL for the referenced chartId. Module: [`IntegratedChartsModule`](https://www.ag-grid.com/vue-data-grid/modules/). |
| `downloadChart` | `Function` |  |  | Starts a browser-based image download for the referenced chartId. Module: [`IntegratedChartsModule`](https://www.ag-grid.com/vue-data-grid/modules/). |

You can use the `downloadChart(params)` API to download the chart image in the browser.

Alternatively for programmatic use-cases, the `getChartImageDataURL(params)` API returns the chart image as string (base64 encoded); this is ideal for persisting to a back-end, or opening/presenting the chart image statically.

The example below demonstrates how you can retrieve images rendered from the chart in multiple formats.

- Click **Download Chart Image (PNG)** to download a PNG format image via `getChartImageDataURL()`
- Click **Download Chart Image (JPG 800x500)** to download a custom size image via `downloadChart()`
- Click **Open Chart Image (JPG)** to open a JPEG format image in a new window via `getChartImageDataURL()`
