Calculators are not professional advice
Financial calculators (loan EMI, interest and GST) use standard formulas and the figures you enter. Lenders and tax authorities may apply fees, rounding rules, different compounding or rates that change over time. Results are estimates and are not financial, tax or legal advice.
The BMI calculator is a general screening measure for adults and is not medical advice. It does not account for muscle mass, age, sex, ethnicity or pregnancy. Consult a qualified professional about your health.
File conversions
Converting or compressing files can change them. Image conversions remove metadata and may reduce quality; strong PDF compression turns pages into images; formatters rewrite whitespace. Keep your original files until you have checked the output.
Security tools
The JWT Decoder decodes tokens but does not verify signatures. Password protection strength depends on the password you choose. Do not treat any tool as a substitute for a professional security review.
External content
QR codes and previews may contain links to websites we do not control. Check where a link leads before opening it. We are not responsible for third-party content.
Browser and device limits
Every tool runs inside your browser, so results can depend on the browser you use and the memory available on your device. Very large files may fail on phones or older computers, and a few features — such as the colour eyedropper or native QR detection — exist only in some browsers. Each tool page lists its specific limitations.
Availability and changes
The tools are provided free of charge and “as is”. We may improve, change or retire a tool at any time, and we cannot guarantee that the site will always be available. Keep your original files and save important results locally.
