DocViewKit Omni · For Browser
No upload required—view documents directly in your browser.
Choose or drop a local file, or right-click a document link on the web, to preview it safely in a separate tab. Documents are processed on your device and never pass through DocViewKit servers.
Free to useNo telemetryOn-demand origin access
Local filesChoose or drop a file; its bytes stay in the extension page
Remote linksRight-click a document link to start a one-time preview
Minimal permissionsRequest only the exact origin required for the selected link
No remote codeViewer and format components are packaged with the extension
More direct, more controlled.
The extension does not take over every download, read browsing history, or request site-wide access during installation.
Preview web links
Use the context menu on a document link, approve its origin, then fetch from the source website and render locally.
Clear privacy boundaries
No document content, filenames, paths, browsing history, usage statistics, or diagnostic telemetry is collected.
Isolated failures stay isolated
A damaged or incompatible object is isolated where possible so one problem does not hide the entire document.
