About ToolHub

ToolHub is a free collection of online tools — calculators, converters and everyday utilities — built for people who want quick answers without ads overload, sign-ups or privacy trade-offs.

Our philosophy

• Privacy first. Every tool runs entirely in your browser. Your data is never uploaded to a server, logged or shared.
• Free forever. No accounts, no paywalls, no usage limits.
• Fast by design. Static pages, no bloated frameworks, works on slow connections and old devices.

How it's funded

The site is supported by unobtrusive display advertising and occasional affiliate links. Ads never interfere with the tools, and we never sell your data — because we never collect it in the first place.
