FAQ

A: An HTML fragment contains only the converted body tags and is suitable for inserting into an existing page or backend editor; a complete HTML document includes DOCTYPE, head, body, and basic styles, and can be saved directly as a standalone web page file.

A: Three types of plain text files are supported: .md, .markdown, and .txt. After conversion, the extension will be changed to .html while keeping the original file name. If duplicate names are encountered, a numeric suffix will be automatically added to distinguish them.

Answer: When the content includes syntax such as tables, task lists, strikethrough, automatic links, fenced code blocks, and more, it is recommended to enable GitHub Flavored Markdown to get more complete HTML conversion results.

Answer: After “Filter dangerous HTML” is enabled, the tool will remove scripts, event attributes, iframes, forms, and high-risk links. This is suitable for processing Markdown content from unknown sources. If you need to keep trusted tags, enable “Preserve raw HTML” before converting.

Answer: Heading anchors add stable ids to headings, while the table of contents generates jump links based on second- and third-level headings. They are suitable for longer articles, technical documentation, tutorials, and manuals.

Answer: Formatted output preserves line breaks and structure, making it easier to read, copy, and edit further; compressed output reduces unnecessary whitespace and is suitable for scenarios where file size needs to be controlled.
