Free online tools that just work

Yes. Every tool is free, with no sign-up and no account. If the site shows advertising, ads are kept clearly separate from the tools and never block a tool or its download.

No. Calculators, text, developer, image, PDF and file tools run inside your own browser. Files you choose are read locally and the result is created on your device, so they are never sent to our server. Two internet utilities need a server by their nature: What Is My IP Address (our server reads the address your request came from) and Website Status Checker (our server requests the address you type). Neither stores what it sees.

Yes. Every page adapts to small screens, buttons are large enough to tap, and image and PDF tools work with your phone’s photo library and Files app. A recent version of Chrome, Safari, Firefox, Edge, or Samsung Internet is recommended.

Each calculator uses the standard published formula, shown on its page with a worked example, and validates inputs to avoid silent mistakes. Results are estimates for planning: banks, schools, and government offices may apply their own rounding, fees, or rules, so confirm important figures with them.

Tools check your input before calculating. An error appears when a value is missing, outside the supported range, or in the wrong format, such as text in a number field or an unsupported image type. The message explains what to change.

Yes. Text, code, images, and numbers you produce with the tools are yours to use. Please check generated output, such as robots.txt rules or meta tags, before publishing it on a live website.

Current versions of Chrome, Edge, Firefox, Safari, and Samsung Internet. Very old browsers may not support the image encoders or secure random numbers some tools rely on; the tool tells you when a feature is unavailable.

Use the Contact page. Tell us which tool you used, what you entered, and what you expected to see, and we will look into it. Suggestions for new tools are always welcome.
