Is WPS Office safe?
What actually happens to your files — and how to decide when it fits.
🛡️ A neutral look — facts about the software, not a takedown
WPS Office, made by Kingsoft, is a broad, MS Office-compatible suite. It encrypts local files with AES-256 and offers cloud sync across devices, which you can turn off in settings. The thing to weigh isn't the company — it's the model: like any suite built around an account and cloud, its connected features route data through servers. For sensitive documents, where the file is processed is what matters.
What happens to your files
WPS Office works primarily as installed software that edits files locally on your device, with AES-256 encryption available for local files. It also offers cloud sync across devices, which you can turn off in settings.
When connected features and cloud sync are on, the relevant data routes through servers — as it does in any account-and-cloud suite. The practical question is which features you use and whether sync is enabled for a given file.
So is it actually safe?
For everyday work, WPS is a capable, widely used office suite with local AES-256 encryption and optional cloud sync. It earns that credit.
For confidential material, the consideration is structural, and the same one that applies to every cloud-and-account suite: when sync or connected features are on, data routes through servers. Keeping a sensitive file local — or processing it in-browser — keeps that question from arising.
Why in-browser processing removes the question
When a tool does its work entirely inside your browser, your file stays on your device and isn't sent to a server — so sync settings, account state, and server locations stop being relevant.
That's the model Vikone uses for redaction: the file stays on your device, and you can confirm it yourself.
How to verify any tool yourself
You don't have to take anyone's word for it. Two quick checks tell you whether a file leaves your device:
Go offline
Disconnect from the internet and try the tool. If it still works, the processing is happening locally — nothing is being uploaded.
Watch the Network panel
Open your browser's developer tools, go to the Network tab, and run the tool. If you see your file being sent in a request, it's leaving your device.
When using WPS is perfectly fine
Plenty of tasks don't need browser-only processing:
- Non-sensitive documents — public forms, drafts, throwaway files.
- Local editing with cloud sync turned off.
- Everyday office work where cross-device sync is convenient.
For anything sensitive that you'd rather not sync, keeping it local or using an in-browser tool sidesteps the question entirely.
Need to redact something sensitive?
Vikone redacts PDFs entirely in your browser — the file stays on your device.

Does WPS upload my files?
Local editing stays on your device. When cloud sync or connected features are on, the relevant data routes through servers — you can turn sync off in settings.
Does WPS store my files?
Files you keep local stay on your machine, with AES-256 encryption available. Files you sync are governed by its cloud settings and privacy policy.
Can I use WPS for confidential documents?
For confidential files, keep them local with sync off, or use an in-browser tool, so the data isn't routed through a server.
What's a more private alternative for redaction?
A tool that processes in your browser keeps the file on your device. Vikone's redaction works this way, and you can verify it by going offline.
