You know allofthose codescreenshots you see on Twitter? Though the code’s usually impressive, we saw room for improvement in the aesthetic department. Carbon makes it easy to create and share beautiful images of your source code. So what are you waiting for? Go impress all of your followers with your newfound design prowess.

  • Customization. Customize things like your image’s syntax theme, window style, and more
  • Share quickly. Save your image or

  • Paste your code directly

Once you’ve got all of your code into Carbon, you can customize your image by changing the syntax theme, background color, window theme, or padding.
After you’ve customized your image you can either Tweet a link to the image, or save it directly.
If you use the ‘Tweet’ button, Carbon will automatically make your image accessible. However, if you want to manually tweet your image, please check out how to make your Twitter images accessible.
If you include a Carbon image in a post, the source code will be invisible for assistive technology, it will not be possible to enlarge it or copy it, etc. Please, think about adding another element with the source code as text, like an HTML Details Element below the image.
