Preguntas frecuentes
RST (reStructuredText) is a document format used to store paginated text, with optional formatting, tables, images, hyperlinks, headers and footers. It sits in the documents & text family and is typically associated with a specific office suite or publishing pipeline that defined the format and ships the canonical reader.

Modern office suites — Microsoft Word, Google Docs, LibreOffice Writer, Apple Pages — open most RST files with reasonable fidelity. If your installed software does not support RST, convert to DOCX or PDF first using KaijuConverter; both open in virtually every reader, including free online viewers.

Upload the RST 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 RST (frames, legacy macros) may flatten to static content in the target format.
