imgp

Only handles JPEG and PNG images, excluding modern formats like WebP or AVIF, which are increasingly common for web optimization and could limit its utility in diverse environments.

Lacks a graphical user interface, making it less accessible for users unfamiliar with terminal commands or preferring drag-and-drop workflows, as hinted by comparisons to Nautilus Image Converter.

Requires Python 3.8+ and PIL/Pillow, which can be a hurdle in environments where Python is not installed or where system packages are restricted, adding complexity over standalone binaries.

Using the --overwrite option can lead to potential race conditions and data loss if *_IMGP files are reprocessed, as warned in operational notes, requiring careful manual management.
