I want to backup my clipboard history as a .txt or pdf file. Currently, I’m on KDE’s default clipboard manager klipper.
I don’t think it is a way to do so but you can always ask for the feature.

You can sync clipboard with your android system easily with KDE Connect (KDE Integration)
Finally found it under
/home/USERNAME/.local/klipper
But it is in the .lst format and when open it in the kate shows text with a lot of other Unicode stuff maybe it’s due to the images I had under it.
