About ToolBox Hub

ToolBox Hub is a collection of small utilities that developers, designers, students and office workers reach for constantly — formatters, converters, encoders, calculators and generators. The idea is simple: put them all in one fast, honest place.

Everything runs in your browser

Every tool is implemented in client-side JavaScript. Nothing you type or drop into a tool is uploaded, logged or stored. That is not a policy promise we ask you to trust — it is how the site is built, and you can verify it in the network tab of your browser’s developer tools.

Fast, and installable

Pages are statically generated and served from a CDN, so they load in milliseconds. ToolBox Hub is also a Progressive Web App: install it once and the tools keep working with no connection at all.

How it is funded

The site is free and funded by advertising. Ads are placed below the tool rather than around it, never inside a result area, and never where they could be clicked by accident. If that ever stops being true, it is a bug — please report it.

Open source

ToolBox Hub is built with Next.js and TypeScript and released under the MIT License. Bug reports and tool suggestions are welcome through the issue tracker.
