DOCX to DOC moves the words and leaves the layout
A portal still asks for .doc, the Word format from before 2007.
The text is pulled out of the DOCX and saved as a Word file the browser can write. Images, headers, and text boxes are not rebuilt. The download is for simple wording, not a designed letterhead.
When this DOCX file should stay in the original app
If the portal can take DOCX, send DOCX. Check the .doc in Word before you submit it. A scan pasted as a picture will not become editable text.
When DOCX to DOC is the right page
DOCX to DOC sits on this site because DOCX and DOC are not interchangeable, even when they look similar in a file list. A portal still asks for .doc, the Word format from before 2007. Use DOCX when someone must change the wording, not only read it. People meet DOC on old email attachments and on forms that were never updated.

What you give up by leaving DOCX
DOCX is the Word file people edit today. Word, Google Docs, and LibreOffice all open it. A browser conversion into DOCX will not rebuild text boxes, headers, or a magazine layout from a PDF.
Keep the file you edited. A PDF made from the text is a reading copy, not the master.
What you gain, and do not gain, with DOC
The download has to be DOC, because that is the format the next step named. People meet DOC on old email attachments and on forms that were never updated. If the other side truly cannot open DOCX, a simple DOC of the words can unblock them.
What you get here is the wording in a Word file, not a clone of an old template.
A test that matches the real file
Start from the question the other software asked. If it asked for DOC, DOCX to DOC is the matching page. If it asked for something else, switch tools instead of hoping a similar extension will pass. A portal still asks for .doc, the Word format from before 2007. The text is pulled out of the DOCX and saved as a Word file the browser can write. Images, headers, and text boxes are not rebuilt. The download is for simple wording, not a designed letterhead. The limit is the part people skip, and it is the part that decides whether the download is usable. If the portal can take DOCX, send DOCX. Check the .doc in Word before you submit it. A scan pasted as a picture will not become editable text. The file stays in your browser and is not uploaded. The limit is 100 MB. Keep the original until the download has been opened in the program that will use it. Check three things in the download: it opens, the DOCX material you cared about is still there, and the file size or the layout is what the form described. A new extension alone is not those three things. If a portal, a teacher, or a client rejects the file, send them the original DOCX as well when you are allowed to. DOCX to DOC is a convenience copy. It is not a new master. Document tools on this site carry words. DOCX to DOC will not clone a brochure, a letterhead, or floating images. If the page has to look exact, export from Word, Google Docs, or LibreOffice. Use this download for a draft, a paste, or a simple handoff, and keep the file you can still edit.
Here is the decision for DOCX to DOC. You start with DOCX and you stop when a real program accepts DOC. It stores paragraphs, basic headings, and tables well enough for drafts and letters. Browsers cannot read a real Word 97 binary document, and they cannot write a certified legacy DOC with full styling. If those two sentences describe a tradeoff you do not want, do not convert. Renaming the extension by hand will not do this job. Running the tool twice on its own output will not do it either.
If the portal can take DOCX, send DOCX. Check the .doc in Word before you submit it. A scan pasted as a picture will not become editable text.
A related step, if you still need one, is DOC to DOCX.
Other jobs start from the homepage, where each tool is named for the conversion it actually does.
