About Byte Utility
A free collection of 88 browser-based tools for developers and everyday use. No installs, no accounts, no nonsense.
Instant results
Every tool runs entirely in your browser. Zero server round-trips — results appear as you type.
Zero tracking
No analytics, no cookies, no accounts, no ads. Your data never leaves your device, period.
Works offline
Pure client-side JavaScript. Once loaded, the tools work without an internet connection.
Works everywhere
Runs in any modern browser on desktop or mobile. No installs, no extensions, no dependencies.
Privacy promise
We built this because we were tired of tools that require sign-ups, collect your data, or show ads. Here's exactly what we do and don't do:
- No user accounts or sign-up required
- No analytics scripts (no Google Analytics, no Plausible)
- No third-party cookies or tracking pixels
- No data sent to any server — all processing happens in your browser
- localStorage is used only for tools that need it (templates, notes, preferences) and only in your browser
- Clearing your browser data removes everything
