Free Online Utilities – Words, Passwords, QR

Online utilities

Small tools you reach for all the time: count the words and characters in a text, create a strong password or passphrase, make a QR code for a link, your Wi-Fi or a WhatsApp chat, and test how fast you type in words per minute.

There's also a case converter that changes text to UPPERCASE, lowercase or Title Case, and a JSON formatter that validates and pretty-prints JSON. Everything runs entirely in your browser — your text and passwords are never sent anywhere — and works in any language.
