When to use Code to Image
You're writing a dev blog post about a tricky TypeScript generic pattern and need a shareable image of the snippet — without setting up a GitHub Gist or taking a terminal screenshot that looks like it was captured on a 2009 laptop. Paste your code, pick a syntax theme, adjust font size and padding, and shiki handles the highlighting while html2canvas renders a high-resolution PNG. The output is the kind of clean code card you see on Twitter threads and conference slides. Supports JavaScript, TypeScript, Python, Go, Rust, and most C-like languages. Rendering happens on your device — proprietary logic or unreleased features in the snippet never reach an outside server.
- Create a clean code card for a TypeScript tip on a dev blog post
- Share a clever algorithm snippet on a conference slide deck
- Post a pull request pattern to a Slack thread without a GitHub Gist
