Possible disadvantages

  While Okular provides basic annotation features, it lacks advanced PDF editing capabilities like modifying text and images within a PDF.
• Learning Curve
  New users might find the extensive range of features and settings overwhelming, leading to a steeper learning curve compared to simpler document viewers.
• Performance Issues
  Some users have reported performance issues when handling very large files, which can result in slower operation and responsiveness.

  To get the best experience, Okular requires KDE libraries, which might not be ideal for users who prefer not to integrate KDE components into their system.
• Mobile Support
  Okular does not have a dedicated app for mobile platforms like Android and iOS, limiting its usability on tablets and smartphones.

Possible disadvantages

• Steep Learning Curve
  For users who are not familiar with command-line interfaces or the specifics of PDF and PostScript formats, it can be difficult to learn.

• Performance
  Processing large or complex documents can be resource-intensive and may result in slower performance, depending on the system's capabilities.
• Complex Configuration
  Ghostscript requires detailed configuration for certain operations, which can be challenging without sufficient technical expertise.
