Why UtilityBase
Simple tools, done right
Instant
Every tool loads fast and works immediately. No installs, no waiting, no setup screens.
Private by design
Most tools run entirely in your browser. Your text, images, and mic or camera streams are never uploaded. A few that fetch live data connect to an external service, and say so.
No accounts
Nothing to sign up for and nothing to subscribe to. Open a tool, use it, close the tab.
Actually useful
Each tool is built to solve a real task well, with clear instructions, sensible defaults, and no clutter.
Free online tools that work in your browser
UtilityBase is a growing collection of free browser-based utilities for everyday tasks. Test your hardware with the keyboard tester, microphone tester, or dead pixel test. Work with text using the word counter and case converter. Generate secure passwords, random numbers, and UUIDs, or handle quick math with the percentage calculator.
Everything here runs client-side using standard web APIs, which means your data stays on your device and the tools keep working even on a slow connection once the page loads. There's no account to create and no software to install, just open the tool you need and get on with your day.
