Sobre los archivos MDComparativa de ventajas
HTM Ventajas

MD Ventajas

Limitaciones
HTM Limitaciones
- No real reason to use .htm over .html in 2026.
- Inconsistent with modern naming conventions.
- Mixed extensions within one site confuse static-site generators.
MD Limitaciones
- No formal authoritative spec — CommonMark, GFM, and MultiMarkdown differ on edge cases.
- Tables and complex layouts are clunky; footnotes and math require extensions.
- Links to images stay external — no embedded media unless you base64-inline.
- Styling is limited to what HTML allows — custom branding requires CSS outside Markdown.

Upload the HTM to KaijuConverter and pick DOCX, PDF, ODT, RTF, HTML, Markdown, or plain text. Our pipeline runs LibreOffice headlessly plus pandoc for text formats — the same engines behind professional document pipelines. Styles, tables, images, and hyperlinks survive the conversion intact.
Yes, to a high degree. Standard fonts, headings, lists, tables, images, hyperlinks and page structure transfer cleanly. Custom fonts substitute to the closest match if not embedded; obscure layout features unique to HTM (frames, legacy macros) may flatten to static content in the target format.
