+Description: This script converts a PDF file to WebP images. It includes functionality to resize images if they exceed specified dimensions and handle conversion of PDF pages to WebP format.
+
+Example
+-------
+To convert a PDF file to WebP images with each page as a separate WebP file:
+    python script.py input.pdf output_directory
+
+To convert a PDF file to a single WebP image:
+    python script.py input.pdf output_directory --single
+
+To adjust the DPI resolution for rendering PDF pages:
+    python script.py input.pdf output_directory --dpi 150
