Change resolution in Illustrator

[miguelc55285804]

Hi all!
how can i change the resolution on a design started at 72ppi to 300ppi?
I work with Illustrator v 26.0.3 on iMac and the operating system is macOS Monterey - version 12.1
Thanks

Illustrator files generally don't have a resolution - that is one point of using vector.

There is a resolution on the raster effects within the file. That can be changed under Effects > Document Raster Effects Settings

Thank you very much for your clarification.
I greet you sincerely
