# Delimiter.live

> Delimiter.live is a free collection of browser-based and web-based text, data conversion, formatting, extraction, encoding, developer, and network utility tools.

All tools are free, require no account, and each tool page states whether it processes data in your browser or on the server. 115 tools across 6 categories, plus guides, reference tables and topic hubs.

## Data processing

- Text, data conversion, developer, extraction and encoding tools run entirely in the visitor's browser. Input is never transmitted to Delimiter.live.
- Network tools (DNS lookup, IP lookup, HTTP header checker, URL redirect checker, My IP) and the QR code generator and bcrypt tool run on the server. Input is processed to produce a response and is not stored in a database.
- The IP lookup tool passes the address you enter to a third-party geolocation provider.
