Why Koaris
Private by design
Most tools process everything locally in your browser. Nothing is uploaded unless a tool clearly needs a server.
Free, no strings
No account or trial to manage. Every tool is free to use, with any processing limits explained on its page.
Fast and focused
Each tool does one job well, loads quickly and works on desktop and mobile.
