FAQ

Are my files uploaded?

No. Localkit is a static web page. Files are read and processed by your own browser and never sent to a server. You can verify it in the DevTools Network tab or by going offline.

Is it free?

Yes. There is no account, no watermark and no file limit beyond what your device memory allows.

Does it work offline?

Yes. After the first visit the app is cached, and it can be installed as an app on desktop and mobile.
