About Us
Ci Pattern Studio is an independent online toolkit that brings practical calculators and converters together in one clean, fast website. No installation, no sign-up, no clutter.
What we offer
Our tools cover everyday tasks such as unit and size conversion, JSON formatting, encoding, date calculations, colour conversion and fitness estimates. Every tool is free and opens directly in your browser.
How the tools work
All calculations run locally in your browser using JavaScript. The text and numbers you type are never uploaded to our servers, which is also why the tools work instantly and keep working when our backend is under maintenance.
Why it is free
Running a website still costs money. We keep the tools free through unobtrusive advertising and, on some pages, affiliate links to products that fit the tool you are using.
Who we are
Ci Pattern Studio is maintained by a small independent team. We build tools we would want to use ourselves: clear results, readable explanations, and no dark patterns.
