Yes. Every tool on TL3 Tools runs entirely in your browser using JavaScript. Your text, files, images, and data never leave your device. We do not transmit, store, or have access to anything you process through these tools. This is a fundamental design decision — all processing is 100% client-side.
Yes. TL3 Tools is completely free to use. There are no paywalls, usage limits, account requirements, or subscription fees. You can use any tool as many times as you like, for any purpose.
No account or sign-up is required. All tools are accessible immediately without registration. We do not track individual users or tie usage to accounts.
Yes. The site is fully responsive and works on smartphones, tablets, and desktops. Tool interfaces adapt to smaller screens with touch-friendly controls and input fields.
Since all processing is client-side, performance depends on your device. For text tools, large files (several MB) work well. For image tools, very large images may take longer to process but still work locally. We recommend keeping files under 50 MB for the best experience.
We use a minimal cookie to remember your cookie preference (accepted or rejected). Google Analytics and Google AdSense may set their own cookies. No personal data is collected by us. You can reject cookies when prompted. See our Privacy Policy for full details.
Yes, you need an internet connection to load the tool page and the required JavaScript files. Once loaded, the actual data processing happens locally in your browser. Some tools have additional features (like downloading generated images) that require browser capabilities available even offline once the page is cached.
We support all modern browsers including Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge. Internet Explorer is not supported. We recommend keeping your browser updated to the latest version for the best experience.
We offer tools across several categories: Text Processing (case conversion, find/replace, sorting, diff checking), Developer Tools (JSON formatting, Base64 encoding, regex testing), Calculators & Converters (BMI, age, unit conversion, finance), Generator Tools (passwords, QR codes, UUIDs), CSS & Design Tools (gradients, shadows, color palettes), Image Tools (resizing, format conversion, color picking), and Math & Science tools.
Our calculators use standard formulas and JavaScript's double-precision floating-point arithmetic, which provides sufficient accuracy for general-purpose use. For example, BMI uses the standard WHO formula, BMR uses the Mifflin-St Jeor equation, and financial calculators use precise amortization formulas. Critical decisions should always be verified with a professional.
We regularly maintain and update our tools. Bug fixes are typically deployed quickly, while new features and new tools are added on an ongoing basis. Check back periodically to see what is new.
