Frequently Asked Questions

How does the code to image converter work?

It uses a custom regex-based tokenizer to parse your code into keywords, strings, numbers, comments, and other token types. Each token is colored according to the selected theme. The live preview renders via HTML, and the PNG export draws everything onto an HTML Canvas for a pixel-perfect image.

What programming languages are supported?

JavaScript, TypeScript, Python, HTML, CSS, Go, Rust, and Java have dedicated syntax highlighting. There is also an auto-detect mode and a generic fallback that highlights common patterns like strings, numbers, and comments.

Is my code sent to a server?

No. Everything runs 100% in your browser. Your code never leaves your device — tokenization, rendering, and PNG export all happen client-side using native browser APIs.

Can I customize the exported image?

Yes. You can choose from 5 themes, adjust padding, font size, border radius, and background color. You can also toggle macOS-style window chrome (the red/yellow/green dots).

What image format is exported?

The tool exports PNG images at 2x resolution (using devicePixelRatio) for crisp output on high-DPI displays. The image is generated using the native Canvas API.
