This class represents a file converter.

For a list of all members of this class, see [converter Members](https://www.aurigma.com/docs/us8/JA_AllMembers_T_J_$au_converter.htm.md).

## Syntax
 
```
$au.converter = function() {
}
```

## Remarks
 
ActiveX/Java Uploader allows sending so-called *converted files* for each of the user-selected files. These files are configured using the [converters](https://www.aurigma.com/docs/us8/JA_P_J_$au_uploader_converters.htm.md) property of the [uploader](https://www.aurigma.com/docs/us8/JA_T_J_$au_uploader.htm.md) object. This property accepts a collection of [converter](https://www.aurigma.com/docs/us8/JA_T_J_$au_converter.htm.md) instances. Each converter describes one file (source, thumbnail, icon, or ZIP archive) to be uploaded for every file a user selects.
 
For instance, you set the following collection of converters:
 ```
var u = $au.uploader({
    id: 'Uploader1',
    converters: [
        {mode: '*.*=SourceFile'},
        {mode: '*.*=Thumbnail;*.*=Icon', thumbnailFitMode: 'Fit', thumbnailWidth: '120', thumbnailHeight: '120'}
    ]
});
``` 
It means that ActiveX/Java Uploader will send an original file and its resized copy or icon. So if a user selects two files (a JPEG image and a PDF document) ActiveX/Java Uploader will send four files:
 
- the JPEG image and the PDF file themselves,
- a resized copy of the image and a PDF icon.
