QR Code Studio — Web Edition
Choose a QR type — Text, URL, Wi-Fi, vCard & more — fill in the fields, then click Generate QR Code. The QR is rendered instantly in your browser using the qrcode library. Nothing is sent anywhere.
Pick custom foreground & background colors, set the output size up to 1024 px, adjust the quiet zone margin, and overlay your own logo image at the center. Use ECL H when adding a logo.
Choose from L, M, Q, or H error-correction levels. Higher levels let scanners recover data even if part of the QR is damaged or covered by a logo — at the cost of a denser, more complex code.
Share your Wi-Fi credentials without typing. Enter the SSID, password, and security type. Anyone who scans the code on Android or iOS will be prompted to join your network instantly. No apps needed.
Switch to the Read tab to decode QR codes. Point your webcam at a code for live scanning, or upload an image file. Decoding uses jsQR — 100% local, no server, no upload.
The Batch tab lets you paste a list of inputs — one per line — and generate all QR codes at once. Download the entire set as a ZIP file containing individual PNG images, named by content.
CrunchyQR runs entirely in your browser. Your Wi-Fi passwords, contact info, and URLs never leave your device. No servers, no logs, no tracking. Close the tab — history is gone by design.
