0 bytes uploaded. Markdown Prettifier runs entirely in your browser using JavaScript. Your markdown — including any secrets, PII, or proprietary content — never leaves your device. No data is sent to any server.
No — content inside fenced code blocks is always left untouched. Line wrapping only applies to prose paragraphs.
Prettify adds structure: it wraps long lines, adds blank lines around headings, and normalises list indentation. Minify removes structure: it strips excess blank lines and whitespace. They are complementary operations.
Strip trailing whitespace, collapse excess blank lines, remove HTML comments, and normalise heading spacing for minimal Markdown storage. Free, instant.
