# PDFViewer.config

```ts
get config(): Readonly<ResolvedPDFViewerConfig>
```

Resolved configuration: your options over the defaults, with what the license does not cover switched off (its tools, and `toolbar.print` / `download`). Its `tools` names every tool: `false` for one you, the mode or the license switched off, otherwise your options for it or `true`. Follows the rights of the viewer's document: grows at once when they grow, and narrows only when pages are imported or another document is opened.

- Kind: getter
- Since: 1.0.0

Returns `Readonly<ResolvedPDFViewerConfig>`

```ts
const canSign = viewer.config.tools.sign !== false;
```
