What are the best online platforms for self-publishing and sharing my completed comic book?

Several online platforms are ideal for self-publishing your comic book. **Webtoon** and **Tapas** are popular platforms for serialized webcomics, offering built-in audiences. For digital distribution that can also be printed on-demand, consider **ComiXology Submit** (via Amazon), **Gumroad**, or **Itch.io**. These platforms allow you to upload your comic files and sell them directly to readers. You can also create a dedicated website or use social media like Instagram and Tumblr to share your work and link to purchase options.
