How to convert DOC to DOCX
- Choose your files. Click Select File or drag your DOC files into the upload box. You can add many at once.
- Pick the settings. DOCX is already selected as the output format. The conversion starts as soon as a file is added.
- Download. Each file appears in the list when it is ready. Download them one by one, or all together with Download all.
Why convert DOC to DOCX?
Old DOC files can open in compatibility mode with features switched off, and some websites and apps only accept DOCX. Converting gives a modern Word file that is smaller and works with current Word, Google Docs and phones.
When to keep the DOC
There is little reason to keep using DOC, except for very old software that only reads it.
Tips for the best result
- Text, formatting, tables and images are carried over.
- Open the DOCX and check complex layouts, such as text boxes and drawings, which can shift slightly.
- DOCX files are usually smaller than the same DOC.
Common problems and fixes
- A drawing or text box moved.
- Old drawing objects are rebuilt in the new format. Drag them back into place in Word.
- The file is password protected.
- Remove the password in Word first; protected files cannot be opened for conversion.
DOCX – Microsoft Word Document
DOCX is the standard Microsoft Word format. It stores text, styles, images and tables in a zipped XML package.

Frequently asked questions
Will macros be kept?
No. DOCX cannot contain macros. Use the DOCM format if you need them.
Can Google Docs open the result?
Yes. DOCX opens in Google Docs, Word, LibreOffice and Word on phones.
How do I convert DOC to DOCX?
Click Select File or drop your DOC file onto the upload box. The converted DOCX appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
