About DOC to DOTX Conversion
Short answer: yes, you can convert DOC to DOTX online for free, and quality is well preserved with the right settings. Just upload your .doc file to CocoConvert, pick DOTX as the output, and click Convert. The whole process takes seconds.
Now for the details. DOC is the legacy Microsoft Word format (pre-2007) — still widely circulated. DOTX is a widely used file format. Converting between these two formats lets you convert between formats quickly.
