You have a .doc or .docx and the machine in front of you has no Word. Upload it here and it opens in the browser — no plugin, no ActiveX, no client-side install of any kind.
The Word viewer takes nine extensions: DOC, DOCX, ODT, RTF, DOCM, DOT, DOTX, DOTM and OTT, up to 15 MB per file. Spreadsheets and slides have their own pages — the online excel viewer for .xls and .xlsx, and the online powerpoint viewer for .ppt and .pptx.

You always wanted to know if there is any free online word doc viewer? The answer is our website, Doconut.app! There are no sign-ups or pop-ups. Just free to use. If you love the site and would like to have it in your Website or WebApp, please check Doconut.
The usual problem is a computer without Microsoft Office — a borrowed laptop, a locked-down work machine, a phone. The document opens here regardless, in every major browser, desktop or mobile.
You can print what you are reading, and printing to PDF works the way it does for any page in your browser, so a DOCX can leave here as a PDF if that is what you needed. What the site does not do is convert files: there is no format menu, because it is a viewer.
Your document is deleted once you have viewed it, and there is nothing to sign up for.
If you want this viewing inside your own site or archive rather than on ours, that is a different product: the Doconut .NET SDK, which installs into WebForms, MVC, .NET Core or Blazor applications and runs in your environment. Doconut.app itself is a website, not a component — there is nothing here to embed.
