Frequently asked questions
Quick answers to common questions.
Is KitSlick really free?
Yes — 100% free. No tier limits, premium restrictions, or catches.
Are my files or data stored anywhere?
Never. Your strings, media inputs, or scripts remain local within memory space inside your web sandbox runtime environment.
Does it work offline?
Yes! Since computation happens entirely client-side, most conversion, encoding, and formatting tools load and process without network dependencies.
Are there any limits on file size?
Limits depend mostly on your browser's allocated hardware memory capability since no processing happens on shared remote servers.
Why should I use KitSlick instead of other tools?
No tracking popups, zero mandatory registration friction points, uniform dark mode, and uncompromising performance utilities built intentionally for immediate delivery.
Your privacy is our top priority
All processing happens locally in your browser. We don't collect, store, or share your data.
