About the Code Image Generator
Code shared as a screenshot communicates better than code shared as a wall of chat text — syntax highlighting, alignment, and framing survive the journey through Slack, Twitter, and slide decks. This generator renders your snippet with a chosen theme, window chrome, and background, and exports a crisp image, entirely in your browser.
Use it for conference slides, documentation callouts, social posts announcing a release, or incident retrospectives where a highlighted diff lands better than a paste. Since rendering is local, proprietary code never leaves your machine.
Frequently asked questions
When should I share a code image versus a text snippet?
Images are for presentation — slides, social media, blog heroes — where visual polish matters and nobody needs to copy the code. For collaboration, always pair the image with copyable text or a gist link: an image can't be copy-pasted, searched, or read by screen readers.
What makes a code screenshot readable?
Short snippets (under ~25 lines), a font size that survives projection, a high-contrast theme matched to the context (dark themes wash out on bright projectors), and trimming to just the relevant lines. If you need to scroll the image, the snippet is too long for this medium.
Why export at 2x resolution?
High-DPI displays and slide zoom both magnify the image; a 1x export looks blurry the moment it is scaled. 2x exports stay sharp on retina screens, in PDFs, and when platforms recompress the upload — at the cost of a larger file, which rarely matters for a snippet.
