What Kitharu is for
Shrinking a photo, timing a lap, and spelling a Korean name come up often, and installing a program each time is a nuisance. Kitharu is a free set of tools for finishing that work in the browser. There is nothing to install and no account to make. Categories and stars make a tool easy to find again.
Documents, calculators, text, image compression, and Korean name spelling finish in this browser. The files you choose and the text you type are not sent to a server. When the work is done, the result stays on your device. Kitharu does not keep a copy.
