What is a uop file?
UOP stands for Uniform Office Presentation. It’s the presentation file format within the Uniform Office Format standard, an open document specification developed in China as an alternative to both Microsoft’s Office formats and the international OpenDocument standard.
UOF was built as a comprehensive office suite standard covering the three core document types. Word processing, spreadsheets, and presentations. UOP handles the presentation layer of that trio, the same role PPTX plays in Microsoft’s ecosystem and ODP plays in the OpenDocument world. Under the hood it’s XML describing the presentation structure, compressed into an archive, the same general approach modern open formats take.
The format exists primarily within Chinese office productivity software and government contexts. China developed UOF partly to reduce dependency on foreign proprietary formats in official and institutional workflows, giving domestic software developers a standardized open format to build around. Outside that context, UOP is rarely encountered.
Compatibility is the practical limitation. UOP files are handled by Chinese office applications that support the UOF standard, but the format has minimal support in the international software ecosystem. PowerPoint, LibreOffice, and Google Slides don’t open UOP files natively. If you receive one outside a Chinese software environment, your options for viewing it without the right application are limited.
ShareOtter renders UOP files in the browser so you can view the presentation contents without tracking down UOF-compatible software, which for most people outside China means software they’ve never installed and may not easily find.

How to Share uop Presentations Online
Three steps. No account, no software, no waiting around.
Select or Drop your File
Drag your UOP into the upload box above, or click to browse. Either way works.
Let it upload
Watch the progress bar. Most UOP files are done in a few seconds. Bigger files can take a little longer.
Copy your link
Done. Grab the link and send it anywhere. Slack, email, text, WhatsApp wherever your file needs to go.
Everything You Need to Share Files, Nothing You Don't
Sharing a file shouldn't mean losing control of it the moment you hit upload.
Instant Shareable Link
Upload once, get a link instantly. No waiting on emails to send, no attachment size limits bouncing your file back — just a clean URL you can paste anywhere, ready the second your upload finishes.
Password Protection
Lock any file behind a password before sharing. Only people with both the link and the password can open it, so sensitive files stay sensitive even if the link ends up somewhere you didn't intend.
Link Expiry Control
Set a link to expire after a day, a week, or whatever window makes sense. Once it's gone, it's gone — no stale links floating around in old emails months later.
Comments for Feedback
Let people comment directly on the file instead of replying in a separate email thread. Feedback stays attached to exactly what it's about, so nothing gets lost translating between a file and a conversation.
Email-Gated Access
Restrict a file to specific people by email. They'll get a magic link to sign in and view it — no password to share, no guessing who actually opened your file.
No Signup Required
Share a file in seconds without creating an account. Drop it, get your link, send it — sign up later only if you want to manage files long-term.
