Code Snippet to Image

Convert code snippets into beautiful, high-resolution images for sharing

Controls

1function greet(name) {
2  return `Hello, ${name}!`;
3}
4
5console.log(greet('Developer'));

Examples

Share a one-liner on Twitter

Input
const sum = (a, b) => a + b   (JavaScript, Dracula theme, macOS bar on, Sunset Mesh background)
Output
A 2× pixel-ratio PNG of the snippet framed in the Dracula palette on a warm mesh background.

Default to a recognisable dark theme and a vivid background so the snippet pops in a dark feed.

Slide-deck-ready vector

Input
SELECT u.id, u.email FROM users u WHERE u.active = TRUE;   (SQL, Material Light, Transparent background)
Output
An SVG file at infinite resolution that drops cleanly into Keynote or PowerPoint.

SVG export preserves the highlight and shadow at any zoom level, ideal for printed slides.

About this tool

Code Snippet to Image turns a snippet of source code into a shareable graphic — useful for blog headers, Twitter / X posts, LinkedIn carousels, conference slides and documentation where a screenshot reads better than raw monospace text. The editor runs entirely in your browser: you type or paste code, choose a language and theme, tune the frame, and export.

Highlighting is done client-side via Prism-based syntax themes (Dracula, VS Code Dark, Nord, Atom Dark, Material Dark, Material Light). Twelve languages ship in the picker — JavaScript, TypeScript, Python, Rust, Go, SQL, CSS, HTML, Bash, JSON, JSX, TSX — and the visual frame adds an optional macOS traffic-light bar, line numbers, padding and a drop shadow. Rendering uses the html-to-image library to capture the styled DOM node as PNG, SVG or a clipboard image, so the original code never leaves your device.

How to use

  1. Paste your code

    Type or paste source into the editor. Pick the matching language from the dropdown so keywords, strings and comments are highlighted correctly.

  2. Pick a theme and style

    Choose a syntax theme (Dracula, VS Code Dark, Nord, Atom Dark, Material Dark or Material Light), toggle line numbers and the macOS window bar, and adjust padding and shadow sliders.

  3. Set the background

    Click one of the seven background presets — Sunset Mesh, Ocean Breeze, Midnight Purple, Neon Glow, Dark Slate, White, or Transparent — to match your channel aesthetic.

  4. Export as PNG, SVG or clipboard

    Click Export PNG for a high-resolution image, Export SVG for a scalable vector, or Copy to paste straight into a tweet or message.

Use cases

Social media code posts

Turn a tip or trick into an eye-catching image for Twitter/X, LinkedIn, Mastodon or Bluesky.

Documentation and blog headers

Drop a snippet image at the top of a tutorial so the post is recognisable in RSS and link previews.

Conference and slide visuals

Export SVG for crisp projection without the JPEG artifacts you get from re-screenshots.

Newsletter graphics

Embed a styled snippet to break up paragraphs and reinforce the technical topic of an issue.

Common mistakes

Mistake:Picking the wrong language just to get a colour scheme.

Fix:Match the language to the snippet — the wrong lexer produces inaccurate highlighting (strings flagged as keywords, comments missed).

Mistake:Adding a busy background to long code blocks.

Fix:Keep background contrast low so the syntax colours stay readable; reserve vivid backgrounds for short snippets.

Mistake:Exporting at 1× resolution for high-DPI displays.

Fix:PNG export already uses pixelRatio: 2 — use SVG instead when you need to scale the image arbitrarily.
