Frequently Asked Questions

Every utility on our platform executes 100% inside your local web browser sandbox. We do not maintain any backend API servers that receive your inputs. Whether you format a JSON document, decode a JWT token, or generate cryptographically secure hash values, the data is loaded directly into your browser memory and calculated locally. No network request containing your inputs is ever triggered.

Yes! Secure Devutils is engineered as a Progressive Web Application (PWA). During your initial load, a Service Worker registers and caches all static files, page scripts, theme styles, and localization configurations. You can bookmark the page or install it onto your desktop and run it completely air-gapped without an internet connection.

If you are using a Chromium-based browser (Chrome, Edge, Brave, Opera), you will see an Install button in the browser address bar or in our custom homepage PWA banners. Once clicked, the app installs onto your computer, launches in its own distraction-free window, and pins to your start menu or dock.

Because all computing is performed inside your browser, there is no hard server-side limit. The capacity depends entirely on your system's hardware (specifically, available browser RAM). Secure Devutils uses Web Workers to process complex parses in background threads. We successfully support JSON payloads and files up to 100MB+, though very large text strings may experience rendering delays depending on device performance.

No. We do not load tracking cookies, third-party analytics code (like Google Analytics), or telemetry scripts. The only data written to your browser is pure layout settings (language choice and dark/light theme preference) stored locally inside localStorage purely to remember your setup on return.

Our conversions engine handles bidirectional transformations between JSON and YAML, JSON and XML, JSON and CSV/Excel, JSON to C# class structures (POCO), JSON to TypeScript interfaces, and CSS-to-Javascript styling objects.

Yes. Secure Devutils is completely free of charge and built for developers in security-critical or compliance-heavy environments (such as finance, healthcare, or government networks) where pasting proprietary configurations into standard web tools is prohibited.
