See https://learn.gramener.com/guide/contributing/#test-gramex on how to run test cases.
Please add test cases in tests/test_pptxhandler.py. Add a function under TestPPTXHandler called test_png and test_pdf. Just verify that it creates a non-empty PDF and PNG in the correct directory for now.

This should be prs.save(target) -- what if target has a .PPTX in caps? Just retain the original.
Instead, just extract the file_ext -- convert it to lowercase.

I prefer if file_ext in {'.pdf', '.png'} -- i.e. set is faster than list to search in.
Nest this under if target:. You don't need to run this code unless target is specified. Then you don't need to check for pres_name

Use subprocess.run instead.

Check if soffice is in the path using shutilwhich.which('soffice')
If it's not there, use app_log.error() to report an error.

pdf_name will not be required.

Check using shutilwhich.which. Use subprocess.run
Added in code for ppt-pdf/png using subprocess by splitting the extension from target value.
Attaching the link for example usage: python, pptx file.
Screenshots if LibreOffice, ImageMagick (pre requisites) if not installed.
