About Cheeky Tools

Cheeky Tools is 45 free tools — calculators for money, tax and health, image and PDF utilities, marketing tools for people who have to justify a budget, and text and developer tools.

The rules we hold ourselves to

• No email gate on a result. If you came for a number, you get the number. The only place we ask for an email is the full site audit, because it does real work — a crawl, third-party API calls and a generated report.
• Your files stay on your device. The image and PDF tools run entirely in your browser. Nothing is uploaded. Open your network tab and check — that is the point of saying it.
• Every formula is shown. Each calculator publishes its formula and a worked example, so you can check the answer rather than trust it.
• We say what a tool cannot do. Browser-based PDF compression is not Ghostscript. BMI is not a diagnosis. Investment returns are assumptions. Where a tool has a real limit, the page says so instead of quietly hoping you do not notice.
• No fake urgency. No invented visitor counters, no exit-intent popups, no countdowns.

The longer list — including the conversions we refuse to offer, and why — is on what we don't do.

India first

Most free calculators are built for somewhere else and then pointed at India. Ours are not. GST carries the real slab set and the CGST/SGST versus IGST split. BMI shows the Indian ICMR thresholds alongside the WHO ones, because they genuinely differ. The QR generator makes UPI payment codes. The image resizer knows the Indian passport photo size. Amounts are formatted in lakh and crore, because that is how the numbers are read.

Who builds it

Cheeky Tools is a Krimsonhouse property. Krimsonhouse builds AI and automation systems for businesses. Almost every tool here runs in your browser and costs us nothing to serve, which is why there is no reason to charge for it and no reason to nag you. If you find them useful and later want something built, you know where we are.
