Haven't had much luck with the documentation from the raspberrypi site and neither with the os downloads; they don't download as zip folder to extract the files and when I do download them they have a different file format. Even installed the Linux raspi imager. Maybe it's just my outdated windows pc
Select a download. You can then point Pi Imager to the file by selecting custom and picking the file you have downloaded. You do not have to adjust extensions. Pi Imager is looking after that for you providing you are getting the software from the official site.
