# converter.thumbnailResizeQuality Property HTML5/Flash Uploader JavaScript

Supported technologies:
 
Gets or sets a resize quality of the thumbnail (interpolation algorithm).

## Syntax
 
```
$au.imageUploaderFlash({
    converters : [
        {
            //...other params...
            thumbnailResizeQuality: "Low",
            //...other params...
        }
    ]
})
```

```
$au.imageUploaderFlash('uploaderID').converters().set(index).thumbnailResizeQuality(value);
value = $au.imageUploaderFlash('uploaderID').converters().get(index).thumbnailResizeQuality();
```
 
### Property Value
 
Type: **String**
 
The resize quality of the thumbnail.
 
The following values are supported:
 
| Value | Description |
| --- | --- |
| **Low** | Low quality. The image is resized using the standard Canvas functionality (supposedly, bi-linear interpolation). |
| **Medium** | Medium quality. The image is resized using the Lanczos 2-pixel algorithm. |
| **High** | High quality. The image is resized using the Lanczos 3-pixel algorithm. |
 
Default value is **"Low"**.

## Remarks
 
This property makes sense only if the [mode](https://www.aurigma.com/docs/us8/FH_P_J_$au_converter_mode.htm.md) property has `Thumbnail` value.
 
Note, using algorithms better than "Low" increases the time required by the uploader to prepare images. It works 30%-90% slower comparing to the standard resize functionality (the overall impact is less significant especially if the upload takes more time than image resizing).
