remove “tag/” & “page/” from permalinks

Hi,

Do you have a solution to remove “tag/” from permalinks ? Ex : https://www.site.net/tag/hello -> https://www.site.net/hello

Same question but different issue for “page/”. Ex : https://www.site.net/page/2 -> https://www.site.net/2

If it’s too difficult, maybe we can replace these words “tag” and “page” by others.

Thanks !
