Free Code-to-Image Generator — Beautiful Code Screenshots

Sharing code on Twitter/X, LinkedIn or in a blog post lands far better as a beautifully framed image than as a plain copy-paste. PikDraw's Code-to-Image generator wraps your snippet in a polished window with theme, language badge and rounded corners — entirely in your browser, free.

What is the Code to Image — Syntax-Highlighted Code Snippets?

Code-to-Image is a client-side canvas painter for source code. Paste a snippet, pick a theme, and export a high-resolution PNG that frames your code with window chrome, language badge and brand-friendly colours.

Key features

  • Dark, Light, Midnight, Solarized, Dracula themes
  • JetBrains Mono and Fira Code fonts bundled
  • Configurable padding, corner radius and language badge
  • Basic keyword highlighting for major languages
  • Export at 640 / 1080 / 1200 / 1600 / 2400 px
  • PNG output at retina resolution
  • 100% client-side — code never uploads
  • Free, unlimited, no signup or watermark

How it works

We measure the longest line of your snippet at the chosen font size to size the output canvas. The background is painted (theme colour + chrome strip), then we walk the snippet line-by-line and call fillText for each token — keyword tokens use the theme's accent colour, strings another, comments another. Padding and corner-radius are applied via clipping; output is exported with toBlob('image/png').

Why use this tool

Carbon.now.sh is the gold standard but requires sign-in for some features and lives behind a popular brand banner. PikDraw's tool is free forever, has no sign-up gates, runs locally for sensitive snippets, and lets you tweak every visual property.

Common use cases

  • Tech-Twitter / X snippets
  • Blog post code blocks (as images for SEO snippets)
  • Pitch decks featuring product code
  • GitHub README hero images
  • Slack and Discord code shares
  • Conference talk slides
  • Educational and tutorial content

How to use this tool

  1. Paste your code — Drop any snippet into the editor — JavaScript, TypeScript, Python, Go, Rust, shell, anything. The tool preserves indentation, whitespace and Unicode exactly as typed.
  2. Pick a theme — Choose between Dark, Light, Midnight, Solarized and Dracula presets. Each ships with carefully matched window-chrome, font and gutter colours.
  3. Set the language label — Type the language name (e.g. ts, py, sh). It appears as a small badge in the window chrome — purely visual but it adds polish for blog posts and tweets.
  4. Adjust padding & corner radius — Padding slider controls breathing room (16–80 px). Corner radius rounds the window chrome (0–24 px). Defaults match the popular Carbon look.
  5. Download PNG — Export at any width (640 / 1080 / 1200 / 1600 / 2400 px). PNG keeps font edges sharp without compression artefacts.

Who should use this

Developers and tech writers sharing snippets, engineering teams polishing internal docs, product marketers making landing-page visuals, conference speakers preparing slides.

How to get started

Paste your snippet, pick a theme, click Download. Tweak padding and the language badge if you want more polish.

Best practices

  • Keep snippets ≤ 25 lines for readability on mobile
  • Use Dark theme for tech twitter, Light for documentation
  • Pick a language badge that matches the snippet
  • Export at 1080 px wide for X/LinkedIn
  • Pair with Screenshot Beautifier for a final gradient background

Pro tips

  • Keep snippets under 25 lines so they read well on a phone.
  • JetBrains Mono and Fira Code monospace fonts are bundled — pick whichever fits your brand.
  • Use Dark theme for tech twitter, Light theme for documentation.
  • 1080 px wide is the social-media sweet spot.

Expert insights

💡 1080 px Is Magic

Export at 1080 px wide and your code snippet drops onto X/LinkedIn at perfect preview size.

💡 Keep It Short

Snippets under 25 lines read perfectly on phones — split longer code into multiple posts.

💡 Pair the Tools

Run the output through Screenshot Beautifier for an extra gradient background that pops on social media.

Limitations to be aware of

  • Lightweight syntax highlighter — for rich highlighting use a real renderer
  • Single-pane layout in v1 — no split or diff views
  • Custom font upload not yet available
  • Canvas height capped at 32767 px by browsers

Frequently asked questions

Does it syntax-highlight my code?
Yes — basic keyword highlighting for major languages (JS, TS, Python, Go, Rust, JSON, SQL, CSS, HTML, shell). For an in-depth highlighter we recommend pairing this tool with Carbon's CSS, then re-importing here for the chrome.
Can I use my own font?
We bundle JetBrains Mono and Fira Code (web-served as base64). Custom font upload is on the roadmap.
Is the output a screenshot or a real image?
A real, rendered PNG. We paint every character onto a Canvas — there's no underlying HTML or DOM. Pixel-perfect at every export resolution.
Does my code leave the browser?
No. The painter is entirely client-side. The snippet, the canvas and the PNG export all live in your tab.
What's the maximum snippet length?
We support up to roughly 500 lines or 50 KB of source. Beyond that the canvas height (capped at 32767 px) becomes the constraint.
Can I add a custom window title?
Yes — the language badge acts as a title. A full title bar with filename + dot decorations is on the roadmap.
