ToolBrainy offers free online tools for everyday tasks. Our tools are built to be helpful and accurate. Here's what you should keep in mind when using them.
ToolBrainy displays advertisements through Google AdSense. We earn revenue when ads are shown or clicked. Ad content is selected and served by Google and its partners — ToolBrainy does not control which specific ads appear. Advertising revenue is how we keep all tools free for everyone. Clicking an advertisement does not affect our editorial decisions or the functionality of any tool.
All tools on ToolBrainy — including calculators, PDF tools, text converters, and others — provide results for informational purposes only. Always verify results independently for any decision that matters.
For financial, medical, legal, or technical decisions, consult a qualified professional. ToolBrainy results are not professional advice.
Tools such as the Currency Converter, Mortgage Calculator, Salary Calculator, and Percentage Calculator are for informational and educational purposes only. They do not constitute financial, investment, tax, or legal advice. Exchange rates, interest rates, and tax rules change frequently and vary by jurisdiction. Always consult a licensed financial adviser before making financial decisions based on any tool output.
Our calculators (BMI, age, percentage, and others) use standard formulas and are designed to be accurate. That said, they produce estimates, not clinical or professional determinations. A BMI result, for example, doesn't account for muscle mass, age, or individual health factors. Use it as a starting point, not a final answer.
PDF merging, splitting, compression, and conversion results depend on the source file's quality and format. Compressed PDFs may lose some visual fidelity at high compression. Text extracted from PDFs may not preserve exact formatting, especially in scanned or image-based files. Always keep a backup of your original files before processing.
Tools like the Word Counter and Case Converter follow standard rules but may not handle every edge case in every language. They work well for common English-language content. Always proofread output for critical documents.
ToolBrainy is provided "as is" with no warranty, expressed or implied. We make every reasonable effort to keep tools accurate and available, but we cannot guarantee uninterrupted service or perfect results at all times.
Some tools use open-source JavaScript libraries loaded from public CDNs. We don't control those third-party resources and can't be responsible for the content or accuracy of any external sites linked from ToolBrainy.
To the extent permitted by law, ToolBrainy and its team accept no liability for direct, indirect, incidental, or consequential damages arising from using, or being unable to use, this site or its tools.
If a tool is producing incorrect results or behaving unexpectedly, let us know. We take accuracy seriously and investigate every report.
