# Create a transformation

Transformations let you create renditions dynamically, in different dimensions, without regenerating the public link.

When you apply a transformation:

- The system tries to apply a same-type conversion on a file type.
- If the system cannot do such a conversion, it returns the original file.

> [!note]
> Transformations can only be applied to images (for example, .`jpeg`, .`png`, `.gif` files, and so on) and do not support videos, PDFs, or other non-image asset types.

To create a transformation:

1. On the menu bar, click **Manage** :mdiCogOutline:.
2. On the **Manage** page, click **Transformations**.
3. On the **Transformations** page, click :mdiPlus: **Transformation**.
4. In the **Transformation** dialog, fill in the following fields.

    | Field | Description | Mandatory |
    | --- | --- | --- |
    | **Name** | Name of the transformation. | Yes |
    | **Crop** | Type of crop. | No |
    | **Width (px)** | The transformation is scaled to this width depending on the selected **Crop** option. | Only for *Smart crop* and *Crop to center*. |
    | **Height (px)** | The transformation is scaled to this height depending on the selected **Crop** option. | Only for *Smart crop* and *Crop to center*. |
    | **Quality** | Quality of the transformation. This parameter is only applied when a format supports a lossy output. For inherently lossless formats, such as `.png` or `.tiff`, the quality parameter has no impact on appearance; and might result in larger files if compression isn’t preserved. For flexible formats such as `.webP`, you must configure quality to avoid defaulting to a high-fidelity (and often bulkier) output. | No |

5. To create another transformation, select the **Create another** check box.
6. Click **Save**. If you selected the **Create another** check box, the **Transformation** dialog displays where you can create another transformation. If you are not creating another item, the **Transformations** page opens.

    > [!note]
    > When you create another item, some of the fields are prefilled with values you already defined.

    After you create the transformation, you can [apply it to public links](https://doc.sitecore.com/ch/en/users/content-hub/apply-transformations.html "Apply transformations").
