EYN Tools

eyn-tools is a utility hub for everyday tasks: convert units and currencies, work with colors and images, generate secure passwords and IDs, inspect your network and device, and edit or analyze text—all in one place with a clean, consistent design.

Convert & calculate Length, weight, volume, and more. Live currency rates. Percentage math, a standard calculator, word count, and age-from-date. Number formatting (scientific, engineering, locale). Binary, octal, decimal, and hex. Time zones with DST-aware conversion.

Color & media Pick and convert colors (HEX, RGB, HSL, OKLCH). Pull palettes from photos. Crop and convert images, compress files, browse storage, and use on-device vision where available.

Security & privacy-minded tools Hashing and encoding, local password strength checks, secure random data, AES encryption for text, and email validation—designed so sensitive work stays on your device when the tool allows it.

Generators Passwords, passphrases, PINs, UUIDs, CUID2, NanoID, names, barcodes, fake sample data, Lorem-style placeholder text, and customizable QR codes.

Text & developers Side-by-side diff, regex testing with matches and groups, Markdown preview, case conversion, timestamps, and a webhook tester for quick HTTP checks.

Device & troubleshooting Battery and screen details, session clipboard history, geolocation with map context, mic test and voice notes, phone info, timers, and network tests—including advanced options for subscribers.
