About

Gauritanaya is a set of free tools for the small jobs that come up every day: combining PDFs, shrinking a photo for an application form, working out a loan EMI or counting the words in an essay.

Why the tools run in your browser

Most online converters upload your file to their servers. Ours don’t. Each tool runs inside your browser, so your Aadhaar scan, salary slip or marksheet never leaves your phone or computer. It also makes the tools fast, because there is nothing to upload or download except the result.

What we promise

• The core tools are free, with no sign-up.
• No watermark on anything you create.
• Clear explanations of how each calculation works.

How the health tools are made

Every health tool uses formulas and thresholds published by health bodies or in peer-reviewed research, and lists them under Sources on its page. Where countries or populations use different standards, such as BMI cut-offs for Asian, Indian, Chinese, Japanese and Korean adults, the tool uses the one for your family background and shows the others alongside. The tools are not reviewed by a doctor and are for general wellness only: they are not a diagnosis or medical advice, and they don’t replace a qualified health professional.

Who runs Gauritanaya

Gauritanaya is a brand of Gauritanaya Enterprises & Ventures, a business based in India. The formulas and thresholds on calculator pages come from the published sources listed on each page.
