Yes. Every core tool is free to use without signup. Pro is optional and adds history sync, saved snippets, larger files, and power-user features.
Does my data leave my browser?
No. Format, encode, decode, generate — all runs locally in JavaScript. Your input never touches our servers.
Why an agency pitch on a tools site?
Same team built every tool you see. If you need that quality on your own product, hire us — single team, no marketplace middleman.
How often do you ship new tools?
New tools every month. The roadmap above shows what's next and what landed recently.
Will it always be free?
The core utilities stay free without an account. Pro funds optional account features such as sync, history, larger limits, and advanced workflows.
Need a team?
