Einschränkungen

PDF Einschränkungen

- Accessibility (screen readers) requires careful tagging that many PDFs skip.

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.
