Paste code, pick a language, get highlight.js-colored HTML you can copy for PPTs or blog posts.
Highlighted output appears here.
Paste code, pick a language (or Auto-detect), and click Highlight. The preview renders with the selected theme. Copy HTML grabs the colored markup (with inline CSS from the theme stylesheet) ready to paste into a blog, PPT or rich text editor. Copy plain text returns the original code. Line numbers can be toggled on. Powered by highlight.js 11.9.0 from CDN; if the CDN fails, the input is shown verbatim.
