Frequently Asked Questions
Is Toolsbase really free?
Yes, all tools on Toolsbase are completely free to use. No account registration is required, and we plan to keep all tools free going forward.
Is my input data safe?
Most tools process data entirely within your browser, and your input is not stored on Toolsbase servers. You can safely use the tools even with confidential or personal information. However, some network tools (such as IP lookup, DNS lookup, and Whois lookup) perform lookup requests to external services to provide results. These tools clearly indicate that behavior on their pages.

Toolsbase supports the latest versions of all major modern browsers, including Google Chrome, Microsoft Edge, Mozilla Firefox, and Safari. We recommend using the latest browser version for the best experience.
Will new tools be added?
Yes, we regularly add new tools. We prioritize developing practical tools based on user feedback and requests. You can submit tool requests through our contact page.
Can I use the results commercially?
Yes, results processed through Toolsbase can be used freely for both personal and commercial purposes. However, please refrain from redistributing the tools themselves or copying site content without permission. See our Terms of Service for details.
