Frequently Asked Questions

Is this HTML to Markdown converter free?
Yes, DevFlow HTML to Markdown Converter is completely free with no usage limits. All conversion runs directly in your browser using the Turndown library — no account or signup required.
Is my HTML data safe?
Your HTML is processed entirely in your browser using pure JavaScript. No HTML is ever transmitted to a server or stored anywhere outside your browser. Your markup stays completely private on your machine.
What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It uses simple plain-text syntax to represent formatting: # for headings, **bold**, *italic*, [links](url), and ```code blocks```. Markdown is widely used for documentation, README files, notes, and content management systems because it is readable as plain text and easy to learn.
What is the difference between CommonMark and GFM?
CommonMark is the formal specification for Markdown, designed to resolve ambiguities and provide a standard implementation. GitHub Flavored Markdown (GFM) extends CommonMark with additional features: tables with pipe syntax, task lists with [ ] checkboxes, strikethrough with ~~text~~, and autolinks for URLs. Use GFM when converting for GitHub, GitLab, or any platform that supports GFM.
What Markdown flavors are supported?
Three flavors are available: CommonMark (strict Markdown specification), GitHub Flavored Markdown (GFM) with tables, task lists, and strikethrough, and Obsidian Wiki Links which converts internal links to [[Wiki Links]] format for Obsidian and similar tools.
How does table conversion work?
HTML tables are converted to GFM pipe-table syntax. The converter preserves header rows, column alignment (left, center, right), and cell content. For example, a 3-column table with a centered header becomes | Header | | with :---: for centered columns.
What happens to complex HTML that doesn't convert cleanly?
For elements that don't have a Markdown equivalent (like embedded iframes, forms, or JavaScript), you can choose to Keep HTML (preserves the raw HTML inline) or Remove Images (strips image tags). The conversion statistics show how much of your HTML was successfully converted.
Can I convert HTML from a website or document?
Yes. Paste any HTML markup — from a website source, a document converter, a CMS editor, or hand-written HTML. The converter handles full HTML documents and HTML fragments equally well. It strips unnecessary document-level elements (<html>, <head>, <body>) and converts only the content.
Does it work offline?
Yes. All conversion logic (Turndown + GFM plugin) is bundled with the page as pure JavaScript. Once the page has loaded, the HTML to Markdown Converter works without an internet connection.
