About
Small tools. Useful connections.
4ool means Tools for All. This is our everyday toolkit for turning information into a simple scan.
A QR toolkit that stays simple
Create a website, text, Wi-Fi, vCard, email, or WhatsApp QR. Read the contents of an image. Arrange the result on a printable card. Each tool works in your browser, without an account or a paid API.
QR codes made here are static: they contain the data you enter, not a service-managed redirect. We do not set an expiration date or a scan limit. A website linked by a QR still depends on its owner keeping that destination available.
Designed for everyday use
Help a guest connect to Wi-Fi, share your contact details, or put a useful link on a notice. Download a vector SVG for flexible sizing or a PNG, JPEG, or WebP for a digital layout. Verify the generated image, then test a real print before sharing it widely.
Your input and selected image files are handled locally. See our privacy notice for the distinction between QR processing, website hosting, and optional advertising.
