About kittokit
For the tasks that need a quick tool: converting a file, checking some text or working out a number.
Get straight to your task
Choose one of 218 tools and get started. No account or software installation needed. The collection includes PDF and image tools, calculators and helpers for code.
Who is behind it
Carina in Höxter, Germany, runs kittokit as a private, non-commercial project. Use the contact details in the legal notice for questions or bug reports. Include the tool, your input and the result you expected.
What happens to your files
With tools that work locally, your files and input stay on your device. That does not hold for every feature. The weather radar loads map and radar images from data providers. Tools with AI models download the model once, and the size is shown on the tool. Each tool explains whether it can work offline or use a server fallback. Anything else a tool needs is stated on its page and in the privacy policy.
Calculators and their sources
Calculators for taxes, salary, loans or health run in your browser. Formulas, rates and sources are listed below the calculator in the how-to section, together with the version and date of the text. Results are a guide and do not replace professional advice.
Make it work for you
Use kittokit in German, English, French or Spanish, choose a light or dark appearance, or install it as an app. The controls support a mouse, keyboard and touch.
