About ABCQR

The project

ABCQR.com is a free QR code generator that runs 100% in your browser. No accounts, no tracking, no ads, no backend. Just type your data and get a QR code instantly.

We built it because most QR code generators are cluttered with ads, require signups, or send your data to remote servers. We wanted something simple, fast, and private.

The entire application is a static website — just HTML, CSS, and JavaScript. The QR code generation uses the open-source qrcode-generator library by Kazuhiko Arase (MIT license).

What you can do

Generate QR codes for links, text, email, phone numbers, calendar events, WiFi credentials, contact cards (vCard), map locations, social media profiles, and WhatsApp messages. Download as PNG or SVG. Customize colors and sizes.
