Turn code snippets into beautiful PNG images for blog posts, tweets, and presentations. Syntax highlighting, themes, custom backgrounds.
About Code to Image
A code-to-image converter turns code snippets into stylised PNG images suitable for sharing on platforms that don't render code well — Twitter/X (no syntax highlighting), Instagram (image-only), LinkedIn, presentation slides, blog hero images. Popularised by Carbon (carbon.now.sh) in 2018. The ZTools Code to Image Converter supports 50+ languages with syntax highlighting (Prism.js), 20+ themes (Dracula, GitHub, VS Code Dark, Solarized, Monokai), gradient/solid/photo backgrounds, drop shadow, line numbers, window-chrome decorations (macOS / Windows / minimal), and exports at 1×/2×/3× DPI for retina-sharp output.
Use cases
- Twitter / X tech threads. X strips code formatting in tweets. Image-rendered code keeps syntax highlighting and reads better. Standard format for tech Twitter threads since 2018.
- Blog hero / cover images. Code-themed blog posts use a code-image as the hero — visually signals "tech content" + draws attention more than a plain title card.
- Conference talk slides. Code in slides needs syntax highlighting + readable font size. Image render matches across platforms (Keynote, Google Slides, PowerPoint) consistently.
- Tutorial / documentation visuals. Stand-out code samples in long-form tutorials. Breaks up the wall-of-text feel; readers scroll-stop on images.
How it works
- Paste code. Pick language manually or auto-detect (works for ~85% of cases).
- Pick theme. Dracula (default), GitHub Light/Dark, VS Code Dark+, Monokai, Solarized, Nord, One Dark, Tokyo Night, etc.
- Configure decoration. Window chrome (macOS traffic-lights / Windows / minimal / none), background (gradient / solid / photo), padding, drop shadow, line numbers.
- Preview. Live render at the export resolution.
- Export PNG. Single PNG at 1×, 2×, or 3× DPI. Ready for tweet, blog, slide.
Examples
Input: React component, Dracula theme, macOS window
Output: 1080×720 PNG with dark theme, traffic-light chrome, indigo gradient background — drop into a tweet.
Input: Python script, GitHub Light theme, no chrome, 3x DPI
Output: High-DPI 2160×1440 PNG suitable for retina blog hero.
Input: SQL query, Monokai, line numbers
Output: Line-numbered code image — easy to reference specific lines in caption / commentary.
Frequently asked questions
How is this different from a screenshot?
Screenshots have unwanted browser chrome, scrollbars, and inconsistent rendering. Code-to-image renders fresh from text with controlled styling — every output looks polished, not "just took a screenshot".
Can I share the original code?
Image is for visual presentation only. Always include a link / gist / paste below for readers who want to copy.
Does it support all languages?
50+ via Prism.js: JavaScript, TypeScript, Python, Go, Rust, Java, C/C++, Swift, Kotlin, Ruby, PHP, SQL, HTML, CSS, JSON, YAML, Markdown, Bash, etc.
Why does my code look pixelated?
Export at 2× or 3× DPI for retina sharpness. 1× is fine for desktop displays but blurry on phones.
Can I include line highlights?
Yes — mark specific line ranges to highlight with background color, drawing attention.
What font is used?
JetBrains Mono / Fira Code / Source Code Pro — pick from a curated monospace selection. Fira Code includes ligatures.
Pro tips
- Always include the actual code (gist / paste link) in the post — image is visual, code is for use.
- Use 2× DPI for retina; 3× only for very-high-res print or 4K screens.
- Limit to 30–40 lines per image — longer becomes hard to read on mobile.
- Pick a theme that matches your brand / audience: Dracula for indie devs, GitHub for corporate, VS Code Dark for general-purpose.
- Window chrome is decorative — minimal/none works for blog heroes; macOS traffic-lights for Twitter aesthetic.
