How to Use Code to Image Converter
Step 1 — Paste your code. Type or paste your source code into the editor on the left. Select your programming language from the dropdown, or leave it on Auto-detect. The tool supports JavaScript, TypeScript, Python, Java, C++, C#, Go, Rust, PHP, Ruby, Swift, Kotlin, SQL, HTML, CSS, JSON, YAML, Bash, Markdown, XML, and Plain Text.
Step 2 — Customize the look. Pick one of 8 syntax themes: One Dark, Monokai, Dracula, GitHub Dark, Nord, Night Owl, Solarized Dark, or Tokyo Night. Choose a gradient background (Sunset, Ocean, Emerald, Twilight, Candy, Carbon, or Transparent). Adjust the font (JetBrains Mono, Fira Code, or Source Code Pro), font size, padding, and panel width. Toggle line numbers, window frame, and shadow on or off.
Step 3 — Export. Click Copy Image to copy directly to your clipboard (for Slack, Twitter/X, Discord, Notion, GitHub Issues), or click Download PNG to save the file. Select 1x, 2x, or 3x scale for different output resolutions.

Frequently Asked Questions
How does Code to Image work? +
Paste your code, pick a theme and background, then export. Everything runs entirely in your browser using JavaScript and the Highlight.js library for syntax highlighting. Your code is never uploaded to any server. Export as PNG or copy directly to your clipboard.
What programming languages are supported? +
Over 20 languages: JavaScript, TypeScript, Python, Java, C++, C#, Go, Rust, PHP, Ruby, Swift, Kotlin, SQL, HTML, CSS, JSON, YAML, Bash, Markdown, XML, and Plain Text. You can also use auto-detect to let Highlight.js identify the language automatically.
Can I copy the image to clipboard? +
Yes! Click "Copy Image" to copy directly to your clipboard using the Clipboard API. Then paste it into Slack, Twitter/X, Notion, Discord, GitHub Issues, or anywhere that accepts images. Requires HTTPS.
Is my code private and secure? +
Yes, 100% private. All processing happens entirely in your browser using client-side JavaScript. Your code never leaves your device, nothing is uploaded to any server, and no data is stored. No signup or account required.
What themes and backgrounds are available? +
8 syntax highlighting themes: One Dark, Monokai, Dracula, GitHub Dark, Nord, Night Owl, Solarized Dark, and Tokyo Night. Each theme has carefully tuned colors for keywords, strings, comments, and other tokens. 7 gradient backgrounds: Sunset, Ocean, Emerald, Twilight, Candy, Carbon, and Transparent (no background).
Can I control the image width? +
Yes. By default, the panel width scales automatically based on your longest code line. You can disable auto-width and set a fixed width (300–1200px) for consistent image sizes. When using fixed width, long lines will wrap automatically at the panel edge.
What fonts are available? +
Three monospace coding fonts: JetBrains Mono (default), Fira Code, and Source Code Pro. All loaded from Google Fonts. Font size is adjustable from 10px to 24px.
Is Code to Image a free Carbon alternative? +
Yes! QuickImg Code to Image is a free, open alternative to Carbon.now.sh. It offers similar features — syntax highlighting, themes, gradient backgrounds — plus adjustable panel width, 3x scale export, and instant clipboard copy. Everything runs client-side with zero server processing, so it works offline after initial load.
