EasyPyPdf

A collection of small pdf tools in python
They are intended to be used on Windows with the "send to" context menu option

combine front and back

This script looks for *.front.pdf and *.back.pdf (with the same name as *)
and combines them into a single file

Front page 1
Back  page 1
Front page 2
Back  page 2

This script reverses the order of pages in a file (it overwrites the original file)

This script saves every page in a single pdf

pip install pikepdf

press [Win]+[R]
enter shell:sendto
a folder will open

here you need to create a link for every main_*.py script

Important: the links need to point to python.exe "C:\path\to\your\scripts\main_*.py"
they cannot directly point to the scripts

the filename of the link will appear in the send to menu
