It is a very good alternative to Sumatra, and evidently its greatest advantage over this are the PDF annotations. Some functions that I use a lot in Sumatra and that are NOT in Okular are:

  • Open multiple files in tabs, in a single window. Okular works Office style, it will open one window per file, which is not practical.

  • File history, and possibility to reopen them ALL automatically when starting the program.

  • In the Windows version, Okular occupies more than 400 Mb, while Sumatra less than 20 Mb.

Finally, a very commented problem is the lack of a "standard" installer in Windows. I had the same problem, and after abandoning all this and trying MuPDF (quite limited) I gave it a last chance, and it turns out that IF THERE IS an installer that is very hidden...the link is below.

There you will find the typical *exe, and also a 7z compressed that will make the portable version (the executable is in the bin folder). If you navigate within that web, you will also find the "Nightly" versions of Okular, and also other applications of the KDE community


Mensaje Original:

Es una muy buena alternativa a Sumatra, y evidentemente su mayor ventaja respecto a esta son las anotaciones en PDF. Algunas funciones que uso bastante en Sumatra y que NO están en Okular son:

  • Abrir múltiples archivos en pestañas, en una sola ventana. Okular trabaja al estilo Office, se abrirá una ventana por archivo, lo cual no es práctico.

  • Historial de archivos, y posibilidad de reabrirlos TODOS automaticamente al iniciar el programa.

  • En la version de Windows, Okular ocupa mas de 400 Mb, en cambio Sumatra menos de 20 Mb.

Finalmente, un problema bastante comentado es la falta de un instalador "estándar" en Windows. Tuve el mismo problema, y tras abandonar todo esto y probar MuPDF (bastante limitado) le di una última oportunidad, y resulta que SI EXISTE un instalador que esta muy oculto...lo encuentran en:

https://binary-factory.kde.org/view/Windows%2064-bit/job/Okular_Release_win64/

Alli encontraran el típico *exe, y tambien un comprimido 7z que hará las veces de versión portable (el ejecutable esta en la carpeta bin). Si navegan dentro esa web, también encontrarán las versiones "Nightly" de Okular, y tambien otras aplicaciones de la comunidad KDE.

Although this might have been true in the past, today Okular does support tabs. You can enable it in the settings.

This is the only PDF (PDF only!) reader that satisfies me fully in all 3 dimensions: open source, functionality and speed. All the other readers that I tried have a shortfall in at least one of the 3 - Adobe Reader, Foxit Reader, Sumatra, DPF.js, STDU, Icecream ebook reader. I won't describe it in full, you'd better try it and see for yourself. I'll just mention my favourite functional features - cursor pointing to the active chapter in the contents tab, Trim margins option, filter field for all tabs - Contents, Thumbnails, Reviews, Bookmarks and a convenient hand tool switch (it's called Browse). But keep in mind - it's good only for PDFs and only for reading. It's bad for reading epubs for example and can't edit files. Also its installation on Windows is hidden somewhy, but all you need to do is install KDE via KDE on Windows from Sourceforge. This installer incapsulates the programs including Okular.

I don't like Okular because the font rendering is terrible (on Windows, at least, haven't tried on other platforms). It seems to completely lack font anti-aliasing, and I found no way to adjust the font type or font display. And since the program is all about displaying text, that's a dealbreaker.

The fact that it's free and open source is reason enough to use it. User-friendly.

It has the best support for various formats like .CBZ, also regularly updated.

It just does what I need: read & print PDF document, highlight text, and add review comments.
