About ToolHive

Fast, private tools that run entirely in your browser.

ToolHive is a growing collection of small, focused utilities — converters, encoders, generators, calculators and PDF tools. Every one of them runs 100% in your browser. Your text, files and images never leave your device, so there is no account to create and nothing to upload.

Verified by design

Each tool is generated from a recipe that ships with real test cases. Those cases are checked automatically before a tool goes live, and the exact same code that passes the tests is the code that runs in your browser — no separate, untested build. The worked examples you see on each tool page are drawn from that verified test set.

Private by design

Because everything happens locally, privacy is not a policy we ask you to trust — it is how the tools physically work. No servers see your data because your data is never sent to one.
