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.

Organized for speed
Browse by category or see everything in one list. Jump back to what you use most without clutter.

Some advanced capabilities are offered as eyn-tools Pro (optional subscription or lifetime purchase). Free tools remain available without a subscription.
