A DOCX, an XLSX or a PPTX arrives and the machine in front of you has no Office on it. OnlineDocumentViewer.com renders it in a browser tab instead. Here is what that gets you, and where it stops:
1. No Install, No Account 🚀
Upload a file and read it. No download, no plugin, no sign-up, and no paid tier — 70+ extensions across seventeen viewer pages, all free.
2. Any Device 🔄
Windows, macOS, Linux, a tablet or a phone. The viewer is a web page, so the operating system stops mattering.
3. A Limit Per Format 📏
There is no single site-wide ceiling: 25 MB for PDF, PSD, Visio, TIFF, EPUB and images; 20 MB for Excel, PowerPoint and Project; 15 MB for Word and RTF; 10 MB for CAD and email; 5 MB for HTML, XML and plain text. A drawing and a text file do not cost the same to render.
4. Nothing Is Kept 🔒
The file travels over TLS, renders on the server, and is deleted when the session ends. No account, no library, no second copy. That is the whole privacy story, and it is short because there is nothing left to retain. No certification backs it — we hold none.
5. Free of Charge 💰
Completely free. No licence, no subscription and nothing to upgrade to. The commercial product is the Doconut SDK, a .NET library for teams embedding a viewer in their own software — a different product, not a plan on this site.
What it does not do
It views. No editing, no annotation, no signing, no OCR, no batch upload, and no integration into another application. If you need the contents in a different format, the converters are separate pages.
Start at the viewer hub and pick the page for your format.
