Terms of Use
Last updated: September 2026
By using Best Free Tools (bestfreetools.dev) you agree to these terms. They are short, because the site is simple: free tools that run in your browser.
The service
Best Free Tools provides free online utilities — calculators, converters, generators, formatters and lookups. Every tool runs in your web browser and no sign-up is required. We may add, change or remove tools at any time.
Acceptable use
You may use the tools for any lawful purpose, personal or commercial. You agree not to misuse the site: no attempting to disrupt it, no scraping it in a way that harms service for others, and no use that breaks the law in your country.
Accuracy and reliance
We work hard to make every tool accurate, and each page explains the method it uses. Still, all tools and content are provided "as is" without warranties of any kind. Results that affect health, legal, tax or financial decisions — for example the pregnancy due date or compound interest calculators — are estimates for planning only. Always confirm important figures with a qualified professional.
Your content
Because the tools process everything on your own device, we never take possession of the text, files or data you work with. Your content remains entirely yours.
Advertising
The site is supported by third-party advertising (Google AdSense). Ads are provided by the advertising network; we are not responsible for the content of third-party ads or the sites they link to.
Limitation of liability
To the maximum extent permitted by law, Best Free Tools is not liable for any loss or damage arising from your use of, or inability to use, the site or its tools.
Changes
We may update these terms from time to time; the date above shows the latest version. Questions? See the contact page.
