A raw screenshot of your whole page rarely makes the best share image. You want the hero, not the nav bar and cookie banner.
OpenGraph+ lets you shape the render with a few meta tags: point og:plus:selector at the element to capture, adjust the look with og:plus:style, and set the viewport size so it’s framed correctly on every device. No design tools, no separate export.
Your OG image ends up looking deliberate, because it is.
