image-dired uses convert from the ImageMagick tools suite.

;; PREREQUISITES

And there is this defcustom:
,----
| (defcustom image-dired-cmd-create-thumbnail-program
| "convert"
| "Executable used to create thumbnail.
| Used together with `image-dired-cmd-create-thumbnail-options'."
| :type 'string
| :group 'image-dired)
`----
I don't know about a lisp utility doing what convert does.
