Old Word to docx
Upgrade .doc (Word 97-2003) to .docx (Word 2007+) with text, tables and images kept, one-click download
为什么这个工具要上传文件?
本站其它工具都在你的浏览器里本地处理、文件不出本机;但 .doc 转 .docx 需要服务端文档引擎重排版式模型,纯浏览器无法可靠完成,因此它是本站少数需要上传的工具之一。 上传的文件只用于这一次转换:不写入数据库、不留存在服务器(转换完成立即删除)、不上传到任何第三方、不会被任何人看到。 如果你的文件敏感到「连我们自己都不能经手」,请在本地用 Word「另存为 .docx」完成。

提示:常见文档几秒到十几秒。带打开密码(加密)的文档无法转换,请先去掉密码。
旧 Word 转 docx 的常见用法与效果边界
为什么要转。.doc 是 Word 97-2003 的老格式,新版 WPS 与在线文档协作平台对它的支持逐渐变差(打开慢、版式漂移、部分功能不可用);转成 .docx 后兼容性更好,也方便接着用本站的「Word 转 PDF」。
转换效果如何。文字、段落、表格、图片都会保留,转成 Word 2007 及以后通用的 .docx 格式,兼容性更好。个别老对象(OLE/ActiveX 控件、部分艺术字)可能变成静态图片或丢失;重要材料建议转换后先打开核对再使用。
格式与大小限制。只接受 .doc(Word 97-2003)。.docx 本身就是新格式、无需转换。单文件上限 20MB,超过请拆分文档或压缩其中图片。
Privacy note:文件仅用于这一次转换——不写入数据库、不留存服务器(转换完成立即删除)、不上传到任何第三方。若你的文件敏感到「连转换服务都不能经手」,请用 Word 自带的「另存为 .docx」在本地完成。
FAQ
Every other tool on this site processes locally in your browser and your files never leave the machine; but turning .doc into .docx needs a server-side document engine to re-lay the formatting model, and a pure browser cannot do it reliably - so this tool is one of the upload exceptions. The uploaded file serves this one conversion only: not stored, not retained, deleted the moment the conversion finishes, and seen by no one.
Text, paragraphs, tables and pictures are kept, coming out as the .docx common since Word 2007 with better compatibility. A few old objects (OLE / ActiveX controls, some artistic word effects) may turn into static pictures or be lost; for important material, open the result and check it before use.
The .doc is the old Word 97-2003 format, and newer WPS and online document platforms support it ever worse - slow to open, layouts drifting, some features gone; after converting to .docx compatibility improves, and you can go straight on to the Word-to-PDF tool here.
The cap is 20MB per file; common documents take seconds to a dozen or so. A document with an open password cannot be converted - remove the password first. If a conversion fails, the page says why, and your original file stays untouched.
