About converting DOC to DOCX
DOC and DOCX solve different problems, which is why this conversion is so common. Our converter reads the structure of your DOC file and rebuilds it as a valid DOCX file rather than simply renaming it, so the result opens cleanly in the apps you already use.
DOC is the older binary document format from Microsoft Word. DOCX is the editable document format used by Microsoft Word.
The converter sits in our document converters toolkit alongside PDF, DOCX, DOC, XLSX, XLS, PPTX, PPT, TXT, RTF, ODT, ODS, ODP, CSV, HTML and more. Nothing is installed, nothing is stored, and the output carries no watermark.
