# PDFViewer.createExporter()

```ts
createExporter(config?: ExportConfig): PDFExporter
```

A [PDFExporter](https://kernstra.com/docs/web-sdk/api/pdfexporter) wired to this viewer's form values and signatures. Its defaults are the viewer's `export` option; `config` overrides them. Obtain the exporter here rather than with `new PDFExporter(document)`: it carries what the viewer holds and reports `exportStarted` / `exportCompleted` on the viewer, and an export of the whole document clears [hasUnsavedChanges](https://kernstra.com/docs/web-sdk/api/pdfviewer/hasunsavedchanges) the moment the bytes leave the viewer — whether your upload of them succeeds is yours to track (see [Saving as the user works](https://kernstra.com/docs/web-sdk/guides/replace)).

- Kind: method
- Since: 1.0.0

| Parameter | Type | Description |
