Convert DOC to Word
Ethical Tube's free DOC to Word converter turns DOC documents into Word (DOCX), Microsoft Word's standard document format, using LibreOffice, the open-source office suite. It runs entirely in your browser, so your documents are never uploaded, and it's free with no sign-up or watermark. The first conversion downloads the LibreOffice engine (77 MB) once, and it's cached after that.
Files are converted on your device and never uploaded.

DOC and Word at a glance
What is a DOC file?
DOC is the binary format Microsoft Word used before 2007. It still opens in most word processors, but it's less efficient than DOCX, handles newer features poorly, and current versions of Word open it in compatibility mode. It opens in Microsoft Word, LibreOffice Writer, Google Docs, Apple Pages, and WPS Office.
What is a Word file?
DOCX is the document format Microsoft Word has used since 2007. It stores editable text with styles, tables, images, comments, and tracked changes, and it's what most people mean when they ask for a Word file. It opens in Microsoft Word, Google Docs, Apple Pages, LibreOffice Writer, WPS Office, and the Word app on phones.
Good to know
What changes when you convert DOC to Word
- Text, formatting, tables, and images carry over to Word.
- Macros aren't carried over.
- The first conversion downloads LibreOffice compiled to WebAssembly (77 MB). It's cached, so later visits start quickly.
- Chinese, Japanese, and Korean text may appear in a fallback font.
- Password-protected documents can't be converted.
- It works best on a computer, because LibreOffice needs a lot of memory.
FAQ
Questions, answered
Is this DOC to Word converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with LibreOffice compiled to WebAssembly, so your files never leave your device. Once the page and the engine have loaded, it even works offline.
Why is there a download the first time?
The conversion uses LibreOffice, the open-source office suite, compiled to run inside your browser. It's about 77 MB, downloads once from Ethical Tube's own server, and is cached for next time. Your documents are never uploaded.
Can I convert several DOC files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each Word file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
It works in Chrome, Edge, Firefox, and Safari, but it's built for computers. LibreOffice needs about 1 GB of memory, which many phones can't spare.
What can open a Word file?
Microsoft Word, Google Docs, Apple Pages, LibreOffice Writer, WPS Office, and the Word app on phones.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle documents with hundreds of pages.
