Code Screenshot Generator - Create Stunning Code Images Instantly
Sharing code as plain text can look dull, especially on social media, in blog posts, or in presentations. A well-styled code screenshot grabs attention, preserves formatting, and makes your snippets look polished and professional. This tool lets you generate beautiful code images with syntax highlighting, customizable themes, gradient backgrounds, and macOS-style window chrome, all without leaving your browser or signing up for anything.
What Is a Code Screenshot Generator?
A code screenshot generator takes raw source code and renders it as a styled image. Unlike a plain text paste or a basic screenshot of your editor, a dedicated generator applies syntax highlighting to color keywords, strings, comments, and other tokens according to your chosen theme. It wraps the code in a visually appealing container with optional window controls, line numbers, and a gradient background. The result is a clean, shareable image that looks consistent regardless of the viewer's editor or operating system. This tool performs all rendering client-side using the HTML Canvas API, so your code stays private and never touches a remote server.
How to Use This Tool
Start by pasting or typing your code into the text area on the left. Select the programming language from the dropdown so the tokenizer can apply the correct syntax highlighting rules. Pick a color theme from the six available options: Monokai, Dracula, GitHub Dark, One Dark, Solarized Dark, or Nord. Choose a background gradient from the preset swatches, or keep the default purple-blue gradient. Use the sliders to adjust the container padding, font size, and border radius to get exactly the look you want. Toggle the macOS window dots and line numbers on or off. The live preview on the right updates instantly as you change any setting. You can also edit the filename shown in the title bar. When you are happy with the result, click "Export PNG" to download a high-resolution PNG image, or "Export SVG" for a scalable vector version that stays sharp at any size.
Key Features
This generator supports 16 programming languages including JavaScript, TypeScript, Python, HTML, CSS, JSON, Go, Rust, Java, C++, Bash, SQL, Ruby, PHP, Swift, and Kotlin. Six carefully curated dark themes give your code a professional appearance. Eight gradient backgrounds add visual depth behind the code window. Every parameter is adjustable in real time: padding, font size, border radius, window controls, and line numbers. The title bar displays an editable filename so viewers know what they are looking at. Export options include PNG for raster images and SVG for vector output. The entire tool runs in your browser with zero external dependencies, which means it works offline, loads instantly, and keeps your code completely private.
Frequently Asked Questions
Does this tool send my code to a server? No. Everything runs entirely in your browser using the HTML Canvas API. Your code never leaves your device. There are no network requests involved in generating the screenshot.
What image formats can I export? You can export as PNG for a high-resolution raster image, or as SVG for a scalable vector graphic that stays crisp at any zoom level. Both formats are generated locally and downloaded directly to your computer.
Can I use the exported images commercially? Yes. The screenshots you create are yours to use however you like, including in blog posts, documentation, social media, presentations, or commercial products. There are no watermarks or usage restrictions.
Why does the syntax highlighting not match my IDE exactly? This tool uses a lightweight tokenizer designed for fast, client-side rendering. It covers the most common token types such as keywords, strings, comments, numbers, operators, and function names. For languages with complex grammars, some edge cases may be highlighted differently than in a full IDE. The result is optimized for visual appeal in screenshots rather than compiler-level accuracy.
Can I customize the background gradient? You can choose from ten preset gradient options that cover a wide range of color palettes, from purple-blue and pink-orange to forest green and midnight blue. Each gradient is designed to complement the dark code themes and make your screenshots visually striking.
