I'm new to the world of making mobile and web apps. As part of the learning process, I learned about openGraph protocol to share those cool looking rich links in iMessage / WhatsApp so I wanted those for my various projects. That's when I learned about several different image sizes requirements it has. Instead of spending hours in photo editing tools, I vibecoded a simple web app where you drop your logo and it creates OpenGraph compatible images for you. I've been using it for all my web apps
