## Document() {#default}

Creates a blank Word document.


```js
Document()
```

### Remarks

A blank document is retrieved from resources, and by default, the resulting document looks more like created by [MsWordVersion.Word2007](../../../aspose.words.settings/mswordversion/#Word2007).
This blank document contains a default fonts table, minimal default styles, and latent styles.

[CompatibilityOptions.optimizeFor()](../../../aspose.words.settings/compatibilityoptions/optimizeFor/#mswordversion) method can be used to optimize the document contents as well as default Aspose.Words behavior to a particular version of MS Word.

The document paper size is Letter by default. If you want to change page setup, use
[Section.pageSetup](../../section/pageSetup/).

After creation, you can use [DocumentBuilder](../../documentbuilder/) to add document content easily.
