execute a command recursively on the files of a folder in the matching location, not in the original one

I want to recursively convert files from .docx to .doc in a folder. The problem is that all the output files are created in the folder where I run the following command, not in the location of the source files: find -type f -name "*.docx"-exec libreoffice --convert-to doc {} \; I understand that find gives source files to the libreoffice command and the output obviously has to be in the current location, so how can I use a command to loop recursively into a folder and execute the command from the location where the files is found, not the initial one?
