What image resolution does the exported PNG use?

The exported PNG uses 2x resolution (double the display size) for crisp, retina-quality output. This ensures your code screenshots look sharp on high-DPI displays, social media platforms, and in presentations when projected on large screens.

What is Code Screenshot Generator?

Code Screenshot Generator creates beautiful, shareable images of your source code. Instead of pasting plain text or low-quality screen captures, you can produce polished code images with syntax highlighting, customizable themes, and professional window decorations. The tool supports 12 programming languages with accurate keyword, string, comment, and number highlighting. Choose from five carefully designed color themes (Midnight, Sunset, Forest, Ocean, and Plain Dark), adjust padding and font size, toggle line numbers and window controls, and export to a high-resolution PNG image.

How to Use This Tool

Paste your code into the text area at the top. Select the programming language for accurate syntax highlighting. Pick a theme from the dropdown and adjust padding, font size, line numbers, and window controls to your liking. The live preview updates instantly as you change settings. When you are happy with the result, click "Export PNG" to download a 2x resolution image file. The exported image is retina-quality, making it look sharp on high-DPI screens, social media feeds, and presentation slides.

Why Use a Client-Side Tool?

Everything runs entirely in your browser using the Canvas API. Your code is never sent to any server, which is essential when working with proprietary code, internal APIs, or unreleased projects. There are no watermarks, no sign-up requirements, and no usage limits. The tool works offline and generates images instantly without waiting for server processing. Your code stays private from start to finish.
