Code to image converter

Turn code into a picture—syntax highlighting, themes, PNG download. Local-first. No signup.

What is a code to image converter?

A code to image converter (also searched as code for a picture) turns a source snippet into a syntax-highlighted PNG you can share. Use this free local-first tool when you want a picture of your code for a post or slide—no signup.

Code to image features

A local code screenshot generator.

  • Syntax highlighting

    Shiki themes color the snippet before you export.

  • Share-ready frame

    Optional window chrome, line numbers, padding, and font size.

  • PNG download

    Export 1×, 2×, or 3× so text stays sharp in slides.

  • Copy the picture

    Put the PNG on the clipboard for chat or docs.

How to turn code into a picture

From snippet to PNG.

  1. Paste your code

    Choose the language so highlighting matches the syntax.

  2. Style the frame

    Pick a theme, font size, padding, and whether to show the window bar.

  3. Download or copy

    Save a PNG or copy the picture for a post or slide.

Tips for code pictures

Cleaner screenshots.
  • 01

    Keep snippets short

    A tight function reads better in a social image than a whole file.

  • 02

    Use 2× for slides

    Higher export scale keeps monospace text crisp when the image is scaled down.

  • 03

    Match the theme to the slide

    GitHub Light sits on white decks; dark themes suit dark posts.

  • 04

    HTML pages are a different tool

    For a snapshot of HTML markup rendered as a page, use HTML to PNG Converter.

Great for

When a code picture helps.

  • Social posts

    Share a readable snippet without a raw code block.

  • Talks and docs

    Drop a PNG into slides or a README preview.

  • Reviews

    Highlight one function when discussing a change.

Why export code here

Fast local code-to-image conversion.

  • Local-first

    Snippets never leave the browser for this tool.

Technical notes

How this code screenshot works.
Highlighter
Shiki (TextMate grammars) with a fixed set of languages and themes.
Capture
html-to-image renders the framed snippet to PNG at 1×, 2×, or 3×.
Font
System monospace so export does not depend on a remote font file.
Privacy
Client-side only—no network upload of your code.
