Tools Star Hub provides general-purpose online tools and guides. They are not a substitute for professional advice, including legal, financial, medical, engineering or tax advice.

Calculators perform the arithmetic described on each tool page. Loan, mortgage, paycheck, and sales tax results are estimates from the numbers you enter; they do not look up rates, tax rules, or lender terms. No tool calculates medical doses or engineering loads. PDF text extraction can miss text on a scanned page. Image and PDF compression or conversion can reduce quality. A QR code contains the text you enter, and a scanned link should be read before you open it. The password generator creates a string in your browser. It does not store passwords or replace a password manager.

Tool output can be affected by the values you enter and by browser limits. Check important calculations, conversions, and document changes independently.

The website is provided as is. We do not guarantee that every tool is uninterrupted or free of errors.
