Preview Before You Publish
Writing Markdown without seeing the rendered output is like coding without running the program. This previewer gives you instant visual feedback as you type or paste. Tables render as actual tables, code blocks get syntax highlighting, task lists show checkboxes, and headings display with proper hierarchy. No more pushing to GitHub just to see how your README looks.
GitHub-Flavored Markdown
The previewer supports all GitHub Flavored Markdown extensions: pipe tables with alignment, strikethrough with tildes, task lists with checkboxes, fenced code blocks with language-specific syntax highlighting, and automatic URL linking. The styling matches GitHub's rendering closely, so what you see here is what your audience will see on GitHub.
Checking README Files
Your README.md is the front page of your repository. Before every commit, paste it here to verify: Are the headings right? Do the code blocks highlight correctly? Are the links formatted properly? Does the table look good? A 30-second preview check saves you from embarrassing formatting issues in your public repo.
