# converter.autoReduceDimensions Property HTML5/Flash Uploader JavaScript

Supported technologies:
 
Gets or sets a value specifying what to do if the browser does not allow creating resized copies of specified size.

## Syntax
 
```
$au.imageUploaderFlash({
    converters : [
        {
            //...other params...
            autoReduceDimensions: true,
            //...other params...
        }
    ]
})
```

```
$au.imageUploaderFlash('uploaderID').converters().set(index).autoReduceDimensions(value);
value = $au.imageUploaderFlash('uploaderID').converters().get(index).autoReduceDimensions();
```
 
### Property Value
 
Type: **Boolean**
 
If `true`, the browser will try to produce an image of smaller size (max possible in this browser). Otherwise, it will fail and no image is uploaded.
 
Default value is **true**.

## Remarks
 
Not all browsers are memory friendly enough to generate large images. For example, Safari on iOS cannot create image larger than 5Mpix (very old iPhones - not more than 2MPix). Firefox and IE are limited by 32Mpix.
 
This parameter is used to define a strategy, the uploader should use to handle this situation. If you set `true`, you say "give me as a large image as you are able to generate". However if it is not acceptable (for example, a user places an order for printing), you can set `false` and the uploader will handle it as if it is a non-image file.
 
It makes sense setting it to `false` only if you set the fallback option in the [mode](https://www.aurigma.com/docs/us8/FH_P_J_$au_converter_mode.htm.md) property, for example `"*=Thumbnail;SourceFile"`. This way you will receive an original file if the uploader failed to create a resized copy.
