What Is a Code to Image Converter?

A code to image converter turns a snippet of source code into a picture with syntax colours, a window frame and a background, so it can be shared where plain text formatting is lost: X, LinkedIn, Instagram, slides, newsletters and documentation screenshots. The result is often called a code screenshot, although nothing is captured from your screen; the image is rendered from the text you paste.

This code snippet image generator highlights with highlight.js, offers six editor themes and nine backgrounds, and exports PNG or SVG straight from the browser. A second mode renders a markdown snippet in the same frame, which is handy for release notes and checklists.

How to Make a Code Screenshot

  1. Paste your code in the left pane. Keep it under about 40 lines so the text stays readable at social-media sizes.
  2. Leave Language on Auto-detect or pick one; the detected language is shown under the preview.
  3. Choose a theme, a frame style, a background and the padding. Set Width to a fixed value when several images should match.
  4. Optionally enable line numbers, enter lines to highlight such as 3,5-7, and turn on the watermark.
  5. Pick a scale and click Download PNG, Download SVG or Copy image to paste it directly into a post.

Themes, Frames and Backgrounds

OptionChoicesWhen to use
ThemeGitHub Light, GitHub Dark, Atom One Dark, Atom One Light, Monokai, NordMatch your editor or your brand; light themes print better
FramemacOS traffic lights, title bar with filename, noneTitle bar when the file name matters; none for inline docs
BackgroundSix gradients, solid dark, solid light, transparentTransparent for slides and pages with their own background
Padding16 to 96 pxLarger padding shows more gradient around the window
Scale1x, 2x, 3x2x for social posts, 3x for print and slides
WidthAuto or 600 to 1200 pxFixed width keeps a series of images consistent

Markdown to Image for Social Sharing

Switch the mode to Markdown to image to render a heading, a task list, a table or a quote inside the window frame. The markdown is processed by the same renderer as the site's editor, so GitHub-style checkboxes, inline code and KaTeX math all work. Because social networks flatten markdown to plain text, a markdown to image export is the simplest way to post a formatted changelog, a short tutorial step or a highlighted quote on X or LinkedIn with the formatting intact.

Code to Image Without Uploading Your Code

Everything in this code to image tool runs locally: highlight.js colours the tokens, html-to-image rasterises the preview, and the PNG or SVG is generated in your browser's memory. That makes it safe for proprietary snippets and internal configuration, and it works offline once the page has loaded. For a plain fenced block instead of a picture, use the code block generator; for diagrams, the Mermaid editor exports PNG and SVG the same way.

Frequently Asked Questions

How do I turn code into an image?

Paste the snippet, pick a language or leave Auto-detect on, choose a theme and background, then click Download PNG. The code to image converter renders the framed preview in your browser at 1x, 2x or 3x and saves a PNG; nothing is uploaded to a server.

Is this a Carbon alternative?

Yes. Like Carbon it produces a styled code screenshot with a window frame, gradient background and syntax colours, and adds line numbers, line highlighting, a markdown mode and SVG export. It is free and needs no account.

Which export size should I use for X, LinkedIn or a blog?

2x is a good default: an 800 px wide frame becomes a 1600 px image that stays sharp on phones and retina screens. Use 3x for slides or print, and 1x for chat messages where file size matters more than sharpness.

Can I highlight specific lines?

Yes. Type line numbers or ranges in the Highlight lines box, for example 3,5-7. Highlighted lines get a tinted background and a coloured bar on the left so the reader's eye lands on the change you are explaining.

What does Markdown to image mode do?

It renders a short markdown snippet, with headings, lists, checkboxes, quotes, inline code and even math, inside the same window frame. Use it to share a changelog entry, a checklist or a quote as a picture on social networks that do not render markdown.

Why does Copy image not work in my browser?

Copying a PNG to the clipboard needs the ClipboardItem API, which Safari, Chrome and Edge support but some older browsers and Firefox configurations do not. When it is unavailable the tool tells you and you can download the PNG instead.
