Aegis tool guides
Online utility tools for everyday work
Find a focused browser tool for passwords, hashes, JSON, encoding, QR codes, text comparison, time, numbers, units, and network checks. Each guide explains what the tool does before you open the interactive workspace.
Core utilities run in the browser. See the privacy policy for storage and network details.

Local-first by design
Core transformations happen in the browser, including password generation, hashing, text work, JSON formatting, QR creation, and unit conversion. The speed test makes network requests only when you start it.
