# Apply transformations

You can generate dynamic renditions of an asset using an existing public link without regenerating a new public link by using transformations. You can transform both simple and chained public links using the t={TRANSFORMATION_NAME} parameter in the public link.

Available transformations include width, height, and quality. Which transformations you can use depends on how your [Content Hub solution is configured](https://doc.sitecore.com/ch/en/users/content-hub/create-a-transformation.html "Create a transformation").

> [!note]
> Certain image formats, particularly those stored in lossless mode (such as `.png` or `.tiff`), do not benefit from a quality (q) reduction in terms of visual appearance. As a result, transformations on these files might retain or even increase file size; this can happen when compression is removed or altered. Other formats, such as `.webP`, which support both lossy and lossless modes, can unintentionally default to a larger, near-lossless output if the quality parameter is omitted in the transformation configuration. This means that it is important to explicitly set the `q` value when transforming formats that support multiple compression modes.

To apply transformations:

- To apply a transformation to a public link, append `t={TRANSFORMATION_NAME}` to its URL. For example, `https://<sitecore instance>/api/public/content/Figure1-cropped?&t=w320` resizes the image to a width of 320 pixels.
