Okular
KDE/okularReviewed by Radar
What it does
Okular is the KDE document viewer. It opens PDF, PostScript, comic book files and several image formats, and lets you add notes and highlights that are saved as standard PDF annotations. It is for anyone who reads or marks up documents on a computer. This GitHub repository is a read-only copy of KDE's own code server and has no downloads. KDE offers an official Windows installer (Windows Package Manager ID KDE.Okular, version 26.08.1), and the README sends users to okular.kde.org for downloads.
How easy it is to install

Risk signals (1)
- Infolicense files in licenses folder
The top-level file list includes a LICENSES/ folder, so license texts seem to be present in a per-file layout even though GitHub did not detect a single license file.

What Radar could not check
- Download size and disk space of the Windows installer, since the winget lookup did not report a size.
- Whether every document format listed in the README opens in the Windows version.
- Whether a macOS version is available.
- Which license applies to which part, since GitHub did not detect a single license file.
- How well annotations made in Okular show up in other PDF readers.
