As a superuser, you can use transformations to manage the configuration of preset renditions and have these presets applied to renditions dynamically. Transformations allow you to provide users with renditions, in different dimensions, without the need to regenerate the public link.

The Media processing best practices provide guidelines for deciding which renditions to set according to your business needs.

The Transformations page lets you manage your transformations. To access the Transformation page:

1. On the menu bar, click Manage .

2. On the Manage page, click Transformations.

   A table lists the available transformations.

   Tip

   You can sort the transformations by name or modification date using the sorting buttons above the table. You can also search for the transformation you want using the search tile at the top of the page.

Transformations work as follows:

• The system tries to apply a transformation on a file type and to convert it to the same file type (svg to svg, png to png, gif to gif).
• If the system cannot do such a conversion, it returns the original file.

To add a transformation:

1. On the menu bar, click Manage .
2. On the Manage page, click Transformations.
3. On the Transformations page, on the top right, click + Transformation.

4. On the Transformation dialog box, set the following settings.

   Field	Type	Description	Value	Mandatory?
   Name	String	Name of the transformation.	String value	Yes
   Crop	Drop-down list	Type of crop.	None, Smart crop, or Crop to center	No
   Width (px)	Numerical value	The transformation is scaled to this width depending on the selected Crop option.	Numerical value	Mandatory for Smart crop and Crop to center.
   Height (px)	Numerical value	The transformation is scaled to this height depending on the selected Crop option.	Numerical value	Mandatory for Smart crop and Crop to center.
   Quality	Drop-down list	Quality of the transformation.	None, Maximum quality, High quality, Medium quality, or Low quality	No

5. Click Save.

The following table describes the available crop options.

The dimensions of a transformation are defined by either the width or the height value that you input. The transformation image is scaled to this width or height depending on the selected crop option.

To edit a transformation:

1. On the menu bar, click Manage .
2. On the Manage page, click Transformations.
3. Look for the transformation you want to edit in the table.
4. On the transformation row, click Edit Transformation.
5. Edit the parameters you want.
6. Click Save.

To apply a transformation to an asset, you must append the transformation name to the URL of the public link as a query parameter named t. For example, to apply a transformation called NewTransformation to an asset, append the value &t=NewTransformation to the public link URL:
