HTML 转 Markdown

Convert HTML into clean Markdown

HTML to Markdown turns rendered HTML — articles, CMS exports, scraped pages, email templates, and rich-text editor output — into portable Markdown for docs, READMEs, and static site generators. Need the reverse direction? Use the Markdown to HTML converter.

1. HTML Input

• Editor. Paste HTML markup. Conversion runs as you type, with output rendered in the preview pane.
• Open. Loads a local .html or .htm file up to 2 MB. The file stays in the browser.
• Copy HTML. Copies the source HTML for reuse.
• Clear. Empties the editor but keeps your option choices.
• Stats. Tracks HTML and Markdown size, line count, and word count for content audits.

2. Markdown Preview

• Theme. Dark, light, GitHub, or reader presets help you match the destination platform.
• Expand preview. Opens a full-screen overlay for long documents and complex tables.
• Live render. The preview is rendered from the converted Markdown so you see exactly what readers will get.

3. Options

• Heading Style. ATX (`# H1`) is the modern default. Setext (`H1\n===`) is provided for legacy parsers.
• Bullet Marker. Pick `-`, `*`, or `+` to match your repo's Markdown style guide.
• Code Block Style. Fenced blocks preserve language hints; indented blocks are kept for older Markdown engines.
• Link Style. Inlined links are best for short docs; referenced links keep long-form prose tidy.
• Bold / Italic Delimiters. Choose between `**` / `__` and `_` / `*` to match conventions.
• GitHub Flavored Markdown. Maps tables, task lists, and strikethrough into GFM equivalents.
• Collapse Whitespace. Removes redundant blank lines and indentation from the source.
• Keep Raw HTML. Preserves iframe, video, audio, details, and similar tags so embedded media survives the conversion.

4. Export Markdown

• Copy Markdown. Sends the output to your clipboard for pasting into a code editor or CMS.
• Download .md. Saves the result as a `converted.md` file ready for commits.
• Reset All. Restores the sample HTML and default conversion options.

Production tips

Run the converter on small chunks when migrating large pages — paste one section, validate the Markdown, then move on. Use Keep Raw HTML for embeds (YouTube, Tweet, custom callouts) so they stay functional. After exporting, paste the result into Markdown to HTML to verify the round-trip rendering.
