Cisdem Document Reader is a macOS document viewer that opens PDF and several Windows-focused document formats in one reading app.
What is Cisdem Document Reader?
Cisdem Document Reader is a native macOS document viewer designed to open and read PDF files along with several document formats that Mac users may not handle easily with built-in tools. It helps users view files such as WordPerfect, WPS, XPS, OXPS, DjVu, Visio, and winmail.dat attachments from a single app. The app is aimed at people who receive mixed document types for work, school, or cross-platform collaboration and want a straightforward way to read them on a Mac. It includes viewing tools such as full-screen mode, page thumbnails, zoom controls, bookmarks, search, rotation, and multi-tab reading. It also supports printing and exporting documents or images for wider compatibility. Cisdem Document Reader is published by ENOL INTERNATIONAL CO., LIMITED.

Safety overview
Status: Mostly safe
This is a legitimate document-reading app for macOS. It normally needs access only to the files you choose to open, and that level of access is consistent with its purpose. Documents you read can still contain sensitive business, school, or personal information, so use the app the same way you would any other file viewer and avoid opening untrusted files unless you need to. Removing the app will stop its document viewing and export features, but it should not affect macOS itself.
Recommendation: Keep Cisdem Document Reader if you use it to open PDF, Visio, WordPerfect, WPS, XPS, DjVu, or winmail.dat files on your Mac. If you do not use those formats or prefer other document viewers, you can remove it without affecting normal macOS operation.
