Why browser tools
Utility without installation.
Some work needs an installed application. Some just needs a quick answer. These are for the second kind.
One thing, done well
Each tool does exactly what it is built for. No feature sprawl.
Nothing leaves your device
All computation runs in your browser. Nothing is sent to a server, and there is no account to sign in to.
Also from VCNet
