How do the tools work?

Most of the tools here run directly in your browser. When you merge a PDF or compress an image, the file does not leave your computer, and the result downloads straight to your device. There is no sign-up, no email address and nothing to install. A few tools connect to an outside service to do their job (IP lookup, page speed testing, text recognition from images); this is stated on the tool's page and in the Privacy Policy.

How do I find the right tool?

Tools are grouped into ten categories by what they do: PDF, image, text, calculators, developer, SEO, security, social media, utilities and AI-assisted tools. If you know what you need, type a few letters into the search box at the top of the page. For ready-made sets picked for a job or a need, see Collections.

How should I use the results?

Most calculator pages show the formula and a worked example, so you can see where a result comes from. Calculations that depend on rules, such as tax or salary, use current rates from official sources, but results are still for information only. Before an important financial or legal decision, confirm the result with the relevant authority or a professional. If you think a tool gives a wrong result, send us the page address and the values you entered, and if you want to learn a task step by step, browse the guides.
