Why does my .doc open in Compatibility Mode?

Because .doc is the Word 97–2003 format. Saved as .docx, the document opens normally in current Word, Google Docs and Pages — and is usually smaller too.

Why convert DOC to DOCX?

A .doc file is the binary format Word used from 1997 to 2003; a .docx file is Word's standard format since 2007 — an open, zipped XML package. Word opens .doc files in Compatibility Mode with newer features switched off, and some apps won't open them at all.

How much does it cost?

You can open your file, convert it and check or change everything in the studio before you pay anything. Downloading the finished file is part of every MojoPDF plan — start with the 7-day trial for $1 and cancel any time.

Is it safe to convert DOC files to DOCX here?

Yes. Your file travels over an encrypted connection and stays private to you — nobody else can open it. Projects you save are kept in your account until you delete them, and download links we email you expire after 7 days.
