What local processing means in practice
LocalFlux keeps the conversion path visible: your files are added on your PC, processed on your PC, and saved as new output files without an upload workflow.
No account gate
Use the app without creating an account, entering an email, or signing in to a conversion website.
No telemetry
LocalFlux does not add tracking to normal conversion work.
Originals stay untouched
Converted files are written as new copies, so source files are not overwritten or deleted.
Engines are bundled
ImageMagick, FFmpeg, and LibreOffice are included for supported image, audio, video, and document jobs.
Offline after install
After Microsoft Store installation, normal supported conversions can run without a browser connection.

Straight answers to the main buying questions
Does LocalFlux upload my files?
No. Normal conversions run on your Windows device.
What kinds of files can it convert?
LocalFlux handles common everyday formats for images, videos, audio, and office documents. It focuses on the formats people actually use, rather than promising all-to-all conversion.
Will it overwrite or delete my original files?
Never. LocalFlux always creates a brand new converted copy, leaving your original file completely untouched.
Does it work without an internet connection?
Yes. Once you install it from the Microsoft Store, normal supported conversions can run offline.
How does the app handle all these formats?
LocalFlux bundles trusted, industry-standard tools (like FFmpeg, ImageMagick, and LibreOffice) directly inside the app, so you don't have to install them separately.
