About Share Code Snippets

Share Code Snippets is a browser-based tool that transforms raw source code into beautifully styled, shareable images. You paste code on the left, choose from six editor themes (Dark, Dracula, Monokai, GitHub, Solarized, or Light), set the language label, adjust font size, inner padding, and corner radius, then toggle the macOS-style traffic-light title bar and line numbers on or off. The live preview updates instantly and a single click exports a 2x-scale PNG ready for posting.

The tool is built for the moments when plain monospace on a white slide is not enough: you need code that looks as good as the rest of your design. A Dracula-themed JavaScript snippet with tight padding and rounded corners reads as a deliberately composed graphic, not an afterthought. Unlike an online text editor or a Markdown editor, the output here is a raster image, not text — the goal is visual communication, not editing or storing code.

All image generation runs entirely in your browser via html2canvas. Nothing is uploaded or logged, so proprietary algorithms, interview answers, and client work remain on your machine. There is no sign-up, no watermark, and no usage limit.

Key Features

check_circle

Six built-in themes

Choose between Dark, Light, Monokai, Dracula, GitHub, and Solarized. Each theme ships with carefully matched title bar, line-number, and border colors so the whole card looks cohesive.

check_circle

Adjustable layout controls

Slide font size (14–24 px), inner padding (16–64 px), and corner radius (0–24 px) to produce a card that fits your slide, blog post, or social media crop precisely.

check_circle

macOS-style title bar

Toggle the traffic-light dots and language label on or off. Keeping it on gives the card the familiar IDE look that audiences recognize instantly; hiding it produces a minimal, borderless style.

check_circle

Optional line numbers

Show or hide per-line numbering. Line numbers help readers follow a walkthrough step-by-step; turning them off keeps short snippets uncluttered.

check_circle

2x retina PNG export

html2canvas renders at double pixel density, so the exported image stays crisp on high-DPI screens and looks sharp when embedded in presentations or pinned to social timelines.

check_circle

Client-side, no upload

The entire rendering pipeline runs locally in your browser. Confidential code, work-in-progress algorithms, and any proprietary logic never leave your device.

How to Use

01

Paste Your Code

Type or paste your source code into the input pane on the left. The preview updates in real time.

02

Customize Appearance

Select a theme, language label, font size, padding, and toggle the title bar or line numbers to match your style.

03

Export or Copy

Click "Export as Image" to download a high-resolution PNG, or use "Copy Code" to grab the plain text.

Example

Paste a JavaScript function, choose the Dracula theme, enable the title bar and line numbers, then export — the PNG shows a card with gradient background, traffic-light dots, and line-numbered code.

  let timer;
  return function (...args) {
    clearTimeout(timer);

Common Use Cases

  • arrow_circle_right

    Social media developer content

    Twitter/X, LinkedIn, and Instagram do not render code blocks. Converting a snippet to a styled PNG card lets you share a function, algorithm, or one-liner without losing formatting — and the card gets far higher engagement than a screenshot from an IDE.

  • arrow_circle_right

    Conference slides and webinars

    Slide decks need images, not live text. Export a themed snippet card sized to fit your slide, then drop it in as an image so fonts and colors stay consistent across every viewer machine regardless of which fonts they have installed.

  • arrow_circle_right

    Technical blog posts and documentation

    When a code block in Markdown is too plain or a screenshot from VS Code includes distraction from status bars, export just the snippet with a clean gradient background. The image embeds anywhere and does not require syntax-highlight CSS.

  • arrow_circle_right

    Interview prep and study notes

    Creating flashcards or annotated study sheets? Export a labeled snippet card for each algorithm pattern — the language label, line numbers, and theme help group related cards visually without any extra design work.

  • arrow_circle_right

    Teaching and tutorial screencasts

    When recording a video, a themed code card placed against a slide background is easier to read than a raw editor pane. Export one card per step of the tutorial and drop them into your video editor as overlay images.

Frequently Asked Questions

What is a Code Snippet Sharer? expand_more
A Code Snippet Sharer is a tool that takes plain source code and renders it inside a styled, themed container so you can export it as an image. It is commonly used for social media posts, documentation, presentations, and educational content.
Is my code sent to a server? expand_more
No. All processing and image generation happens entirely in your browser using html2canvas. Your code never leaves your device, ensuring complete privacy.
Which image format is exported? expand_more
The tool exports a high-resolution PNG image at 2x scale, which looks crisp on retina displays and is widely supported across all platforms and social media sites.
Can I use this for any programming language? expand_more
Yes. The language selector provides a label for the title bar, but the tool works with any text content. Simply paste your code regardless of language and it will be displayed with the selected theme colors.
How is this different from the Online Text Editor or Markdown Editor on this site? expand_more
The Online Text Editor and Markdown Editor are for writing and editing content — their output is text you can copy or save. This tool outputs a raster image. You cannot edit the exported PNG; the purpose is visual presentation, not continued editing. Use this tool when you need a shareable graphic, and use the editors when you need to keep the code as live text.
Can I remove the macOS-style title bar? expand_more
Yes. The title bar toggle in the options panel hides the traffic-light dots and language label entirely, leaving only the code block for a minimal card style.
How do I control the size of the exported image? expand_more
The exported PNG width matches the preview card (up to 680 px) and is rendered at 2x scale for retina sharpness. You can adjust padding and font size to change how much space the code occupies within the card, but final pixel dimensions depend on how much code you paste.
Does it do syntax highlighting? expand_more
The tool applies theme colors to the code block background and text, but does not tokenize the code for per-keyword highlighting. All code lines share the theme text color. If you need token-level syntax highlighting in the image, you would need a tool that integrates a full syntax-highlighting library.
