How to Make Aesthetic Code Screenshots
KromaStudio is a free online tool for developers and designers who want polished code screenshots and browser mockups without opening Figma or Photoshop. Everything runs in your browser — no account, no upload.
Three steps
Step 1: Paste your code or upload a screenshot
Open KromaStudio and switch to Code mode to paste a snippet, or stay in Image mode to drop in a screenshot. Supported languages include JavaScript, TypeScript, Python, HTML, CSS, Go, and Rust.
Step 2: Customize the look
Pick a syntax theme like Dracula or One Dark Pro, choose from 12 gradient backgrounds, adjust padding and shadows, and optionally add a headline overlay for social posts.
Step 3: Export HD PNG or animated video
Click Export for a 2× resolution PNG, or open Animate to render Float, 3D Tilt, or Auto Scroll loops as .webm — ready for Twitter, LinkedIn, or Reels.
