JoltFile for desktop
The web converter handles everyday files right in your browser. The desktop app removes the ceiling: files of any size, whole folders at once, formats a browser tab can't touch — with the same guarantee that your files never leave your device.
Why a desktop app?
No size limits
Browser tabs cap out around 1 GB of working data. The desktop app converts multi-gigabyte videos and entire photo libraries without breaking a sweat.
Batch & watch folders
Drop in a whole folder, or point JoltFile at a directory and let it convert everything that lands there — hands-free, in the background.
Global keyboard shortcuts
Convert the file under your cursor from anywhere in the OS. Power users never open a window they don't have to.
GPU-accelerated
Hardware video encoding turns hour-long conversions into minutes — far beyond what a browser sandbox allows.
Fully offline & private
Same promise as the website, with no browser at all: processing happens on your machine, and files never leave your device.
Every pair the web app can't do
EPUB ebooks, PDF → DOCX layout recovery, multi-page PDF → image — the desktop engine covers the full format matrix.
