Your inputs stay on your device

Tools marked “Runs in your browser · No data sent” perform every operation locally with JavaScript and the Web Crypto API. The text, files, and images you paste are never uploaded to a server.

History stays local

Recent operations are stored in your browser's IndexedDB so you can restore them. This history is never synced anywhere and you can clear it at any time from a tool's history panel.

Server-backed tools

A small number of tools (for example DNS or IP lookups) genuinely require a network request to function. These are clearly labelled “Server request required,” and only the minimum necessary data is sent to perform the lookup.
