Try the following script.
NOTE: The output folder should not be under the same path as the input folder (otherwise remove webp from the file format name match).
As you have requested all files to be saved to a single output folder, you need to consider how to handle duplicate files, as the source folder structure may contain files with the same name as they are in different folders, however, when saved to a single common folder there may be duplicates. This script simply overwrites existing webp files without any alert or logging. You will need to check for missing files yourself, as the input file count may not match the output file count.

* Existing webp files with duplicate file names in the output folder will be overwritten without warning!
