Tools

Small tools, handy daily.

A few little utilities I use myself. Everything runs in your browser — nothing you type is sent anywhere.

IP Info

See your public IP, location and network provider. Works from the terminal with curl too.

Turn any text or link into a QR code. Pick colours and download as PNG or SVG.

Random numbers, strings, passwords, UUIDs and placeholder text in one place.

Flip yes or no, true or false, heads or tails — or let it pick from your own list.

What's my device? Check your phone or computer model, OS, screen size, battery level, CPU, GPU and network.

Format, validate and minify JSON, or decode a JWT to see its header, payload and expiry.

MD5, SHA-1, SHA-256, SHA-384 and SHA-512 for text or files — files never leave your device.

Base64, URL, HTML entities and hex with proper UTF-8, so Myanmar text and emoji survive.

Convert epoch seconds or milliseconds to readable dates in any timezone, and back again.

See one moment across cities, with daylight saving handled. Myanmar time included by default.

A serial monitor for Arduino, ESP32 and USB-UART devices. Pick a baud rate, read text or hex, and send commands.
