Frequently Asked Questions

Does this tool add syntax highlighting?

Not currently. The tool renders code in a monospace font with your chosen theme colors. The language selector adds a label to the header for context.

What image format is exported?

Screenshots are exported as PNG files at your display resolution (Retina/HiDPI supported).

Is there a code length limit?

There is no hard limit, but very long code blocks may produce large images. For best results, keep snippets focused and concise.

Does my code get uploaded anywhere?

No. All rendering happens locally in your browser using the Canvas API. Your code never leaves your device.

How is this different from Carbon.sh?

This tool runs entirely offline in your browser with no account or network required. It offers similar theme and customization options with instant PNG export.
