A QR code (Quick Response code) is a two-dimensional barcode that stores data — URLs, text, WiFi credentials, contact info (vCard), payment details (UPI), and more. When scanned with a smartphone camera or QR reader app, it instantly opens the encoded information. QREndlessPro supports 1,421+ QR code types across 38 categories.

Is QREndlessPro free?

Yes, QREndlessPro is 100% free forever. There are no sign-ups, no subscriptions, no watermarks, and no hidden fees. All 7 tools (Generator, Bulk Generator, Customizer, Scanner, Enhancer, Decoder, and Expiry Checker) work entirely in your browser — your data never leaves your device.

What formats does QREndlessPro support?

QREndlessPro supports 7 export formats: PNG, SVG, PDF, EPS, JPEG, WebP, and Base64. QR codes can be generated in any size from 100px to 4096px, with custom colors, logos, and error correction levels (L, M, Q, H). Bulk QR codes can be exported as print-ready Grid PDFs or ZIP archives.

How do I create a QR code for WiFi?

Select 'WiFi' as the QR type in QREndlessPro, enter your network name (SSID), password, and encryption type (WPA/WEP). Click Generate — your WiFi QR code is ready instantly. Guests can scan it to connect without typing the password. You can also bulk-generate WiFi QR codes for hotels, offices, or events.

Can I add my logo to a QR code?

Yes! QREndlessPro's Customizer tool lets you embed a logo in the center of your QR code. It automatically upgrades error correction to Level H so the QR code remains scannable even with 30% of the code covered. You can also add custom colors, gradients, dot styles, and branded frames.

How do I scan a QR code from an image?

Use QREndlessPro's Scanner tool — either drag & drop an image file or use your device camera. It reads QR codes and 13+ barcode formats (EAN-13, Code 128, UPC-A, Data Matrix, Aztec, PDF417, etc.). Bulk scanning is supported — upload multiple images and export results as CSV.

Is my data safe? Does QREndlessPro collect my information?

QREndlessPro is 100% browser-based — all QR code generation, scanning, and decoding happens on your device. Your data is never uploaded to any server. There are no accounts, no tracking, no data collection. The tool even works offline after the first load as a PWA (Progressive Web App).
