Frequently asked questions
What is an MD file?
Markdown is a plain-text format that marks structure with simple punctuation — # for headings, ** for bold, - for lists. It has become the native output format of the AI era: ChatGPT, Claude, Copilot and coding agents all write Markdown, GitHub renders it, and note apps like Obsidian store everything in it. A .md file is just text, which is why it opens in any editor but looks unformatted without a renderer like this one.
Is this safe? Do my files get uploaded?
No upload happens — ever. Rendering your file runs entirely inside your browser. Your documents never leave your device, nothing is stored on any server, and the tool keeps working if you go offline after the page loads. That's also why there are no file size limits, no queues and no sign-up.
Why do I suddenly have .md files everywhere?
AI tools write them. ChatGPT and Claude format every answer in Markdown, and coding agents like Claude Code and Cursor save reports, READMEs and notes to disk as .md files. They're plain text under the hood — the formatting only appears in a renderer like this one.
Which apps open MD files?
Any text editor opens one as raw text (Notepad, TextEdit, VS Code). For rendered reading: this page works on every platform with zero install; GitHub renders them in repositories; Obsidian and Typora are good desktop choices if you work with Markdown daily. To hand one to someone else, convert it to PDF or Word instead.
How do I turn an MD file into a normal document?
Use the converters linked below: Markdown to PDF for a polished, printable file, Markdown to Word for an editable .docx, or Markdown to Google Docs to paste it into a Doc with formatting. Each one runs locally in your browser, like this viewer.
Is there a file size or quantity limit?
There is no hard limit. Server-based converters cap uploads because your files consume their bandwidth and CPU; here the work happens on your machine, so the only practical limit is your device's memory. Even book-length documents convert in seconds — text is light work for a modern browser.
