Code Screenshot Generator — Create Beautiful Code Images Online
About this tool
The Code Screenshot Generator transforms plain code into visually stunning images you can share anywhere — Twitter/X, GitHub, blog posts, presentations, or dev tutorials. Simply paste your code, choose a theme and language, and download a crisp PNG in seconds. No account needed, no watermarks, 100% free.
Unlike plain screenshots, this tool applies professional syntax highlighting across 20+ programming languages including JavaScript, TypeScript, Python, HTML, CSS, SQL, Go, Rust, Java, and more. Each token — keywords, strings, functions, comments, operators — is colored precisely to match the theme you choose, making your code instantly readable even in an image.
The tool runs entirely in your browser, which means your code never leaves your computer. It's the perfect Carbon.now.sh alternative with a cleaner interface, more themes, and instant downloads.

How to Use
Step 1 — Paste your code. Click into the "Code Input" textarea and paste any code snippet. You can also type directly. The preview updates in real time as you type.
Step 2 — Select the language. Use the Language dropdown to tell the highlighter what language your code is. Correct language selection dramatically improves highlighting accuracy — pick from JavaScript, TypeScript, Python, HTML, CSS, SQL, Go, Rust, Java, Bash, and 13 more.
Step 3 — Choose a theme. Click any theme tile in the sidebar. Nine themes are available — from dark workhorses like One Dark and Dracula to light options like GitHub Light. The preview updates instantly so you can compare themes without clicking elsewhere.
Step 4 — Pick a window frame. Select macOS for the classic colored dot chrome, Windows for a title-bar style, Terminal for a minimal prompt header, or None for a fully frameless card. Optionally set a title (like index.js or main.py) to show in the window chrome.
Step 5 — Set your background. Switch between Gradient and Solid in the Background section. Ten preset gradients are available — Midnight, Ocean, Sunset, Aurora, Rose, Dusk, Forest, Amber, Slate, and Transparent. For solid color, use the color picker to choose any hex color.
Step 6 — Fine-tune typography and padding. Drag the Font Size slider (10–22px) and Padding slider (8–80px) to frame your code perfectly. Switch the font between JetBrains Mono, Fira Code, Source Code Pro, Cascadia Code, or Inconsolata.
Step 7 — Set export resolution. Choose 1×, 2×, or 3× scale for the download. Use 2× or 3× for Retina displays and high-quality social media posts. 1× is sufficient for small in-line uses.
Step 8 — Export. Click "↓ Download PNG" to save a crisp PNG file directly to your computer. Or click "Copy Image" to put the image on your clipboard and paste it straight into Slack, Twitter, Notion, Figma, or any image-accepting app.
Common Use Cases
Frequently Asked Questions
Yes — completely free, no sign-up required, and no watermarks on downloads. The tool runs entirely in your browser.
No. All processing happens locally in your browser using JavaScript. Your code never leaves your device. This makes it safe to use with proprietary or sensitive code.
JavaScript, TypeScript, JSX, TSX, Python, HTML, CSS, JSON, Bash, SQL, Java, C, C++, C#, Go, Rust, Ruby, PHP, Swift, Kotlin, YAML, and Plain Text — 22 languages total.
Nine professionally calibrated themes: One Dark, Dracula, GitHub Dark, Monokai, Nord, Tokyo Night, GitHub Light, Solarized Dark, and Night Owl.
Set the Export Scale to 2× or 3× before downloading. This produces a PNG that is 2× or 3× the pixel dimensions of the on-screen preview, perfect for Retina displays and social media.
Yes. In the Background section, select Gradient, then choose the "Transparent" chip (the checkered tile). The downloaded PNG will have a transparent background.
Yes — click the "Copy Image" button. On supported browsers (Chrome, Edge, modern Safari), the image is placed on the clipboard so you can paste it directly into Slack, Notion, Figma, Twitter, or any app.
macOS shows the three colored traffic-light buttons (red, yellow, green) familiar from macOS apps. Windows shows a title bar with minimize/maximize/close icons. Terminal shows a prompt-style header. None shows the code card without any chrome.
Yes — it covers all the core features of Carbon (themes, languages, window frames, backgrounds, download PNG) with a faster, privacy-first, zero-upload approach. Everything runs in your browser.
Absolutely. Export at 3× scale for the sharpest image quality. The 1200×630-pixel standard for social sharing is easily achievable by adjusting padding and font size before download.
JetBrains Mono, Fira Code, Source Code Pro, Cascadia Code, Inconsolata, and the system default monospace — six options covering the most popular programming fonts.
This tool uses a lightweight browser-side tokenizer that covers the most common token types. For full fidelity to a specific editor theme, it would require bundling TextMate grammar files, which would slow page load significantly.
