Notre avis
Okular can replace Sumatra PDF for most users who need a lightweight, keyboard‑friendly viewer that handles PDFs, PostScript, DjVu, EPUB, MOBI and other formats. It offers a richer feature set—annotations, form filling, incremental search, and tabbed browsing—while remaining relatively small. Users who prioritize speed over advanced features may still prefer Sumatra, but Okular provides a solid, cross‑platform alternative with a familiar KDE look.

Ce qui fonctionne pareil
- Both open PDFs and other formats (PDF, PostScript, DjVu, EPUB, MOBI, CHM, XPS)
- Both have minimal UI and support keyboard shortcuts
- Both support tabbed browsing and incremental search
Ce qui change
- Okular adds annotation tools (highlight, underline, note, shape) and form filling, which Sumatra lacks
- Okular integrates with KDE file manager; Sumatra is standalone
- Okular is part of KDE, so it may use more system resources than Sumatra’s ultra‑light footprint
- Sumatra does not support exporting annotations; Okular can export annotated PDFs
- Okular’s UI is slightly heavier than Sumatra’s very minimal interface
Ouvrir vos fichiers Sumatra PDF
Both applications can open PDF, PostScript, DjVu, EPUB, MOBI, CHM, and XPS files. Okular can also export annotated PDFs back to the same format, while Sumatra only displays them. If you have custom configuration files or bookmarks saved in Sumatra’s settings, they will not transfer automatically to Okular.

Okular is slightly heavier because it is part of KDE, but it still starts quickly and uses modest memory. Users who need the absolute lightest footprint may notice a small difference.
