Ask usIs it really free?
Yes. Every tool here is free, no signup required. Pro adds history sync, saved snippets, larger files, and a few power-user-only tools.
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?

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?
Every tool here is free right now, no signup. Down the road we may add a Pro tier for sync, history, and team features — but the core utilities stay free forever.
Need a team?
