Document Converters

Word, Excel, PowerPoint, ODT and RTF to PDF and back. · 5 tools

Documents move between Word, LibreOffice, web pages and note apps, and each step usually mangles something. These converters map structure — headings, lists, tables, links — rather than copying visual formatting, so the result is editable and clean.

Text-level conversions (DOCX to text or HTML, Markdown to HTML and back) run in your browser. Conversions that need a full office engine (DOC, RTF, ODT, HTML to Word) run on our server, where a LibreOffice engine handles legacy formats reliably.

Pick the converter by the file you have and the app you need it in. Word documents going to the web or a wiki become HTML or Markdown; text written in Markdown becomes a DOCX for people who only use Word; legacy DOC and RTF files become modern formats that every current editor opens.

How to choose

Editable or exact?
If you need to keep editing, convert between office formats (DOCX, ODT, RTF). If you need the layout frozen, use the PDF tools instead. HTML and Markdown outputs are deliberately structure-only.
Old files
DOC, RTF and WordPerfect-era files are best converted to DOCX once and archived in that form; the converters keep headings, lists and tables so nothing has to be rebuilt by hand.
Large batches
Every converter accepts several files at once and returns them as one download, and browser-based conversions have no upload wait because the file never leaves your device.
