doc is the document format used by Office Word 2003 and earlier versions. docx is the newer Word format. In terms of compatibility, stability, file size, etc., the docx format offers more advantages, so we need to convert all old doc files to the new docx format. Here is a batch conversion method that can quickly convert hundreds of doc files to docx format with one click, without manually converting them one by one, saving a lot of time.

What are the benefits of batch converting doc to docx format?

1. Improved Compatibility

Modern office software such as Office Word, WPS, and Google Docs prioritize support for the docx format. If you open a doc file with these applications, it is prone to layout errors and feature failures. Therefore, to ensure files can be opened and viewed normally, you need to convert them to the more compatible docx format.

2. Unlock Advanced Features

Many advanced features, such as SmartArt, advanced charts, 3D models, etc., are only available in the docx format, not in doc. So batch converting to docx format allows you to use more efficient tools.

3. Save Storage Space

For the same content, a docx file is 30%–50% smaller than a doc file. After converting all doc files to docx, you can free up more storage space, and the transfer speed will also be faster.

4. Convenient Long-term Management and Archiving

Docx has become an international open standard, offering more guaranteed stability and compatibility. The doc format is gradually fading from the historical stage, with less support in the future, and may even become unopenable one day. Therefore, from a long-term perspective, batch converting to docx format is necessary.
