Overview

QR Code is a two-dimensional barcode standard used to share data quickly through camera scanning. This tool generates QR for URL, WhatsApp link, Wi-Fi network, free text, and PIX key with live updates on each field change.

You can tune technical settings that affect readability and resilience: output size, quiet zone margin, error correction level, and color contrast. You can also add a centered logo with size, roundness, and background controls while preserving scan reliability.

For printed materials, keep high contrast and test with multiple scanner apps before publishing.

FAQ

What content can I encode in the QR?

You can generate for URL, WhatsApp, Wi-Fi, text (up to 1000 characters), and PIX key.

Does adding a logo hurt readability?

It can if the logo is too large or has poor contrast. Use Q/H correction, a light logo background, and test on different phones.

What is this tool for?

It runs fully in your browser: useful to validate, format, or convert data in everyday development.

Are my inputs sent to a server?

Processing happens locally with JavaScript. We do not store what you paste into the text areas.

Can I use this for real production data?

Use at your own risk. For secrets (passwords, tokens), prefer controlled environments and your company policies. And always review the generated contents. Never trust blindly things you see on the internet.
