Frequently Asked Questions

Got questions about our utility suite? We have got the answers.

Are these tools safe to use for sensitive data?

Yes, absolutely. All calculations, formatters, and image resizes occur locally inside your browser cache. No raw files, text strings, or passwords are sent over the network to any server.

How do I use this website offline?

Since our service worker is integrated with PWA standards, once you load this page once, your browser caches the styles, structure, and scripts. You can bookmark and open it in standard offline modes, or install the app via the PWA install icon on your desktop/mobile browser address bar.

Is there any usage limit?

No limits whatsoever. You can use all 23 converters, formatting scripts, and sizing utilities indefinitely without account registrations, credentials, or premium payments.
