Your go-to destination for free, fast, and reliable online tools.
ToolPeg was built with a simple mission: provide high-quality, free online tools that anyone can use without signing up, downloading software, or dealing with paywalls. Whether you're a freelancer calculating profit margins, a developer formatting JSON, or a student converting units — we've got the tool for you.
ToolPeg is created and maintained by Syed Ejaz Ahammed, a full-stack developer passionate about building practical web tools that solve everyday problems. With hands-on experience in Next.js, TypeScript, React, and modern cloud infrastructure, Syed started ToolPeg in 2025 to give freelancers, students, and small-business owners free access to the utility tools they need most — without paywalls or account friction.
Every tool on ToolPeg is hand-built with attention to accuracy, speed, and user experience. The project is continuously improved based on real user feedback and real-world usage patterns.

Privacy is a core design principle, not an afterthought. The vast majority of ToolPeg's tools run entirely in your browser using client-side JavaScript — your data never leaves your device. We do not collect, store, or sell personal data. The site uses minimal analytics solely to understand which tools are most useful, and any advertising is clearly separated from tool functionality.
We are committed to keeping ToolPeg free and accessible to everyone. For full details, see our Privacy Policy.
Accuracy matters — especially for tools that touch finance, health, and payroll calculations. Every calculator on ToolPeg is tested against known reference values, and high-stakes categories include clear disclaimers advising users to verify results with qualified professionals or official sources before making important decisions.
ToolPeg processes most inputs directly in your browser, keeping your data on your device whenever possible. We do not store, sell, or share user data. Our commitment to privacy is built into the architecture, not just the policy.
