This GIMP (GNU) tutorial demonstrates how to convert an image into a fun caricature using GIMP’s IWarp Filter. To work along, you are welcome to download the Start Image I am working with Here. Unzip the file and open the image onto GIMP’s workspace.
You can quickly Undo a step at any time by pressing Ctrl then Z. Alternatively, click a previous Undo History snapshot - Windows then Dockable Dialogues then click Undo History. In addition, to Zoom in (or Zoom out) of your image; from the top menu, choose View then select a Zoom Tool from the subsequent drop-down list.
Ensure the Layers and the Undo History Palettes are visible, and then drag them into position over your workspace - (Windows then Dockable Dialogues - then click Layers and Undo History).

Left-click over the left-side image, and deform your image’s pixels to your liking by dragging your cursor around.
To enlarge (Grow) pixels, mark the following Grow settings, and then left-click over each eye (one at a time), and drag your cursor.
(Don’t click OK).
To Undo a distortion, mark the following Remove setting, then left-click and drag your cursor over the pixels you would like to “reform”.
Shrink Pixels Example
When you are happy with the amount of distortion, click OK.
To create extra impact, apply a Sharpening Filter of your choice - Filters then Enhance.
Congratulations, your Caricature Conversion is complete, and it’s ready to optimise and save.
