Our code screenshot generator supports over 20 mainstream programming languages, including JavaScript, TypeScript, Python, Java, C++, C#, PHP, Ruby, Go, Rust, Swift, Kotlin, HTML, CSS, SCSS, JSON, XML, YAML, SQL, Bash, PowerShell, and more. Each language has specially optimized syntax highlighting rules to ensure code readability and aesthetics.

How do I choose the most suitable code theme?

Choosing a code theme mainly depends on your usage scenario and personal preference. The Dark theme is suitable for night programming and modern displays; the Light theme is suitable for printing and formal documents; the GitHub theme mimics GitHub's code display style; Monokai and Dracula themes are colorful and suitable for creative displays. We recommend choosing a theme based on your target audience and usage environment.

What is the quality of the generated code images? Can they be used for printing?

Our tool supports high-definition output mode, which can generate images at 2x resolution, fully meeting high-resolution display and printing needs. PNG format provides lossless compression, suitable for code images with text; JPEG format files are smaller, suitable for network sharing; WebP format provides a better compression ratio while maintaining quality.

How do I add and customize watermarks?

Check the "Watermark" option in the style settings to enable the watermark function. You can customize the watermark text content, position (four corners), and color. The watermark function is especially suitable for technical bloggers, educational institutions, and corporate users, effectively protecting intellectual property and enhancing brand recognition. We recommend using short text such as website domain or brand name.

Does the tool save or upload my code?

Absolutely not. Our online code to image converter runs completely in your browser, and all code processing and image generation are done locally, without sending any code content to the server. This ensures your code privacy and security, especially suitable for handling sensitive or proprietary code.

How to Use the Code to Image Converter

Select Programming Language

First, select the programming language corresponding to your code from the language dropdown menu. The tool will automatically apply the appropriate syntax highlighting rules to ensure that keywords, strings, comments, and other elements are displayed in different colors, improving code readability.

Selecting the correct language type is crucial for obtaining the best syntax highlighting effect.

Enter or Paste Code

Enter or paste the code you want to convert in the code editor. The editor supports common programming shortcuts and will automatically maintain code indentation format. You can also click the "Load Sample Code" button to view examples in different languages.

We recommend maintaining good code formatting and appropriate comments to make the generated image more professional.

Choose Visual Theme

Choose the code theme that best suits your needs from 8 professional themes. The Dark theme is suitable for modern displays, the Light theme is suitable for documents and printing, and the GitHub theme mimics the style of popular code hosting platforms.

Different themes' color schemes will affect the visual effect and readability of the code.

Customize Style Settings

Adjust parameters such as font, font size, tab size to get the best display effect. Choose a suitable background (solid color or gradient), set margin and shadow effects. These detail adjustments can significantly enhance the professionalism of code images.

Font size is recommended to be between 14-18px, ensuring readability without taking up too much space.

Configure Watermark Options

If you need to add a watermark, check the watermark option and enter the watermark text (such as your website domain or brand name). Choose an appropriate position and color to ensure that the watermark serves as an identifier without interfering with code reading.

The watermark opacity has been optimized to ensure visibility without excessively affecting the code display effect.

Preview and Export

Preview the generated code image effect in real-time, and after confirming satisfaction, select the export format. PNG format is suitable for high-quality display, JPEG format files are smaller and suitable for network sharing, and WebP format provides the best balance of quality and size.

Enabling high-definition output can get 2x resolution images, suitable for high-resolution displays and printing purposes.

Download and Use

Click the "Download Image" button to save the generated code image locally. The image can be directly used in blog posts, technical documentation, social media sharing, presentations, and various other scenarios.

We recommend saving images in different formats for different purposes to get the best usage effect.

Congratulations!
