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.

Convert files locally, without handing them to a website

Get LocalFlux from the Microsoft Store and handle supported everyday conversions on your Windows PC.
