This is really great Jijin P. I have a suggestion, maybe you could add font change support. The UI is 🔥, great solution. Nice work handling the image size according to blogging platforms.
Jijin P What if you added a feature for image generation on API call. For example, the way hashnode does it with Imgix if you post doesn't have a post then, make an API call to generate an image with the article title.
