QuickKit is a small collection of free online tools for everyday tasks: calculating percentages and loan payments, counting words, converting text case, generating passwords and more. The aim is simple: tools that load fast, work on any device and do one job well.
How the tools work
Every tool is written in plain JavaScript and runs inside your browser. When you type text or numbers, the calculation happens on your own device. We do not need your input to produce the answer, so we do not collect it. There are no accounts and no sign-up.
How the site is funded
The tools are free to use. The site may show advertisements to cover hosting and the time it takes to build and maintain the tools. Ads are kept in clearly separated areas of the page. See the privacy policy for details of how advertising and cookies work.
Accuracy and limits
We test each tool's calculations and explain the formulas on its page, but results are estimates for general information. They are not financial, medical, legal or academic advice. For decisions that matter, such as a loan, a deadline or an official GPA, confirm the figures with the relevant institution.
