What this is
ToolTiki is a set of single-purpose tools: converters, calculators, generators and file utilities. Everything runs in your browser — calculations happen on your device and what you type into a tool is never sent to a server. There is no account, no upload and no paid tier. Every tool is free, for everyone, including commercial use.
Who makes it
TecWeb B.V., a small team in Sassenheim, working from a plain rule: one tool, one job, no configuration screens. Every tool cites the standard or formula it implements, and the arithmetic behind the finance and health tools is tested against those published equations rather than eyeballed.
How it is paid for
Display advertising through Google AdSense, and nothing else. Free tools, paid for by ads: that is the whole business model. We do not sell data, run affiliate links inside tools, or place an ad above the tool you came for. Ad slots are fixed per page — one small banner below the tool, one rectangle after the supporting content, and one in the sidebar on desktop.
How we measure
We use Google Analytics to understand which tools are used and how pages perform, and Google Search Console to see how people find us. Analytics runs only after you accept cookies — decline and no analytics script loads at all. What you type into a tool is never part of any measurement.

English and Dutch today. German is next, and the layout is already built to take the extra length.
