Overview
Halftone ASCII is a browser-based tool that converts images into stylized ASCII art using halftone patterns. Inspired by old printers, comic books, and the intersection of generative art and constraint, this project blends utility with a touch of play.
Users can upload an image, customize the halftone shape, density, and brightness sensitivity, and export the result as a high-res image. It’s designed for artists, tinkerers, and anyone who wants to experiment with turning pixels into patterns.
What I Learned
- Built a lightweight UI for interactive image manipulation with HTML5 Canvas and JavaScript.
- Learned how to work with pixel data at scale while optimizing performance.
- Explored the trade-offs of character selection, contrast mapping, and resolution.
What I’d Improve
- Add drag-and-drop support and instant preview thumbnails.
- Support animated GIFs and batch exports.
- Rewrite core logic in WebGL for better performance and stylized effects.
Tech Stack
- JavaScript + HTML Canvas
- Tailwind CSS (for UI)
- Image processing algorithms (custom)
