Falcon PDF

This is a community package of Falcon PDF, maintained independently and unaffiliated with ANRMS Private Limited. It repackages the official upstream .deb unmodified and follows upstream releases automatically. Falcon PDF is proprietary software, free to use with no ads.

Falcon PDF is a cross-platform PDF viewer and editor.

• Fast PDF rendering, search and navigation.
• Annotate, fill forms, edit and sign documents.
• More than 30 PDF tools: merge, split, compress, convert, rotate, reorder, encrypt.
• An eBook reader for EPUB, FB2 and MOBI, with read-aloud.
• Optional favourites sync through your Google Drive.

Permissions: this package grants network access (sync, sign-in, AI summaries and read-aloud voices), audio output, the GPU, and your Documents and Downloads folders. The app's Open dialog shows only those folders. A PDF anywhere else still opens when you open it from your file manager, or you can widen access with an override:

• Browse, open and save anywhere in your home directory: flatpak override --user --filesystem=home com.falconpdf.app

Your library, sign-in and sync state stay inside the sandbox under ~/.var/app/com.falconpdf.app. The app draws its window through X11 (XWayland on a Wayland session). Updates come from this repository.

On a HiDPI screen the window takes its scale from the desktop's X settings. GNOME and KDE provide it; compositors that don't, such as Hyprland with xwayland:force_zero_scaling or sway, leave the interface at 1× and too small to read. Set the scale yourself (a whole number, e.g. 2 on a 200% display):
