Utilities

Everyday utilities for the jobs that come up between the calculations: shrinking a photo to fit an upload limit, putting a link or your Wi-Fi details into a QR code, or creating a password you do not have to invent yourself.

Each one runs entirely in your browser. Images are processed by your browser's own canvas, QR codes are drawn on your device, and passwords come from its cryptographic random generator — none of it is uploaded, logged or kept.
