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 6 tools (Generator, Bulk Generator, Customizer, Scanner, Enhancer, and Decoder) 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).

Does this QR code expiry checker upload my image to a server?

No. The QR code image is processed entirely in your browser using JavaScript and the jsQR library. No image data is ever sent to any server. Your QR code never leaves your device — the tool even works offline after the page loads.

Can this tool tell me when my dynamic QR code will expire?

It cannot predict the exact expiration date because that depends on the QR service subscription. But it can tell you if the QR code is dynamic (may expire) or static (will not expire), and whether the URL is currently working. If the URL is not reachable, the QR code may have already expired.

What types of QR codes never expire?

Static QR codes never expire. These include WiFi QR codes, contact/vCard QR codes, text QR codes, phone QR codes, email QR codes, SMS QR codes, location QR codes, crypto QR codes, and direct URL QR codes where the full URL is encoded in the QR pattern.

My QR code is dynamic and expired. What do I do?

If your dynamic QR code has expired, you need to create a new QR code. Use QREndlessPro's free QR generator to create a static QR code that will never expire. If the old QR code image is blurry, run it through the QR Enhancer first to sharpen it.

What image formats are supported by the QR expiry checker?

The tool accepts PNG, JPG, WebP, SVG, GIF, BMP, and PDF files. PDFs are rendered in-browser with pdf.js. All processing happens in your browser — no file is uploaded to any server. You can drag and drop, click to browse, or paste (Ctrl+V) an image. EPS and AI files are not supported (convert them to PNG, SVG, or PDF first).

Is my data safe when using this QR code checker?

Yes. All processing happens in your browser. Sensitive data like phone numbers, email addresses, and WiFi passwords are automatically masked in the results to protect your privacy. The tool does not set cookies, does not track you, and does not require an account.

How do I know if my QR code is static or dynamic?

Upload your QR code image to this tool. It decodes the data and checks if it contains a direct URL, WiFi string, vCard, or text (static — never expires) or a short redirect URL from a QR service like bit.ly, qrco.de, or tinyurl.com (dynamic — may expire when the subscription ends).

Can I check multiple QR codes at once?

Currently the tool checks one QR code at a time. After checking, click "Check Another QR Code" to upload a new one. Each check takes under 2 seconds — all decoding happens instantly in your browser.

What is the difference between a static and dynamic QR code?

A static QR code stores all data directly in the QR pattern — it never expires and works offline. A dynamic QR code stores a short redirect URL that points to a server-controlled destination — it may expire if the subscription ends or the service shuts down. Dynamic codes allow edit-after-printing and scan tracking, but cost money and have expiration risk.

Is this QR code expiry checker free to use?

Yes, 100% free with no limits. No sign-up, no account, no watermark, no usage caps. Check unlimited QR codes forever. The tool is completely browser-based and works on every device — phone, tablet, and desktop.

What Is a QR Code?

A short, practical guide — what QR codes are, how they work, and where they are used today.

A QR code (Quick Response code) is a square barcode that stores information. When you scan it with your phone camera, it opens a website, connects to WiFi, makes a payment, or shows contact details — instantly.

QR codes were invented in 1994 by a Japanese company called Denso Wave. They were originally used to track car parts in factories. Today, you see QR codes everywhere — on restaurant menus, business cards, product packaging, event tickets, and payment apps.

Static QR Codes

The data inside a static QR code is fixed. Once you create it, the content cannot be changed. Static QR codes are best for WiFi passwords, contact details, and permanent links.

How QR Codes Work

A QR code stores data as black and white squares in a grid pattern. Your phone camera reads these squares and decodes the information. Error correction lets QR codes work even when partially damaged.
