🛠️ Tip: For best conversion results, it is recommended to ensure that the input HTML structure is complete (e.g., containing closing tags).

❓ Frequently Asked Questions (FAQ)

1. Is my data safe? Will it be uploaded to the server?

Completely safe. Unlike other online conversion tools, this tool's conversion logic runs entirely on your browser's local machine. Because no backend processing is required, your HTML content will never be uploaded, stored, or shared, completely protecting your privacy.

2. Which HTML tags are supported for conversion?

The tool follows the CommonMark specification and supports most common tags:

• Headings (h1-h6), paragraphs (p), links (a)

• Bold (strong/b), italics (em/i)

• Lists (ul/ol/li), code blocks (pre/code)

• Images (img), quotes (blockquote), and tables (table)

3. Why do converted images not display correctly?

Markdown only retains the image's link address. If the image in the HTML uses a relative path (e.g., ../images/pic.jpg), it may not be previewable directly in the Markdown editor. It is recommended to use the complete https:// link.

4. Where can the converted Markdown file be used?

The generated .md file has high compatibility and can be used directly with:

• Editors: Obsidian, Typora, VS Code

• Code Hosting: GitHub, GitLab (README documentation)

• Static Blogs: Hexo, Hugo, Jekyll

• Collaboration Platforms: Notion, FlowUs, Lark Docs

5. Will the conversion fail if the HTML source code is very complex (e.g., contains many JS scripts)?

The tool automatically filters out non-content tags such as <script>, <style>, and <meta>. If the webpage structure is extremely complex, we will prioritize retaining plain text content to ensure document readability.

6. Why convert HTML to Markdown?

Markdown is more lightweight and easier to maintain than HTML. It eliminates cumbersome labels, allowing users to focus on text creation, and is currently the most popular technical writing and knowledge management language on the Internet.
