Free online markdown file reader
Open local .md, .markdown, or .txt files and preview them as HTML with syntax-highlighted code blocks, tables, and task lists. Drag and drop a README, switch Split/Preview/Source, and keep the file on your machine — FileReader never uploads it. Max size is 2 MB. Use the Markdown Previewer if you would rather type than open a file.
