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).

100% Private

Every hash is computed entirely in your browser using native Web Crypto. No upload, no server calls, no logging. Your data never leaves your device.

Native Web Crypto

SHA-1, SHA-256, SHA-384 and SHA-512 use `crypto.subtle.digest` — the same cryptographic primitive browsers use for TLS. No npm hash library, no polyfill.

Text & File

Hash any text you type or paste, or drop any file (binary included). Drag-and-drop supported. Up to 500 MB per file to keep the browser stable.

5 Algorithms at Once

Toggle MD5, SHA-1, SHA-256, SHA-384 and SHA-512 simultaneously and compare outputs side-by-side. One-click copy per row, plus Copy All to clipboard.

Is this hash generator safe to use for sensitive data?

Yes. All hashing happens locally in your browser using the native Web Crypto API (`crypto.subtle.digest`) for SHA algorithms and a pure-JS implementation for MD5. No text or file is ever uploaded — there is no network request at all.

Why does the tool include MD5 if MD5 is broken?

MD5 is cryptographically broken and unsuitable for security purposes (passwords, signatures, etc.). It is still widely used as a fast checksum for detecting accidental file corruption and for legacy integration. We show a clear warning whenever MD5 is selected. For any security-sensitive use, pick SHA-256 or SHA-512 instead.

How large a file can I hash?

Up to 500 MB. Beyond that the browser may run out of memory when calling `crypto.subtle.digest`, so the tool shows a warning and skips the file. For very large files you would normally use a streaming hash library, but that requires a polyfill since Web Crypto does not support incremental hashing.

Is SHA-256 suitable for storing passwords?

No. SHA-256 (and any other plain hash) is too fast and easily brute-forced. For password storage you must use a password-specific key derivation function such as bcrypt, scrypt or Argon2 with a per-user salt. This tool is designed for file integrity checks, checksums and learning — not password storage.

What is the difference between SHA-256, SHA-384 and SHA-512?

All three belong to the SHA-2 family. SHA-256 outputs 256 bits (32 bytes / 64 hex chars). SHA-384 and SHA-512 operate on 64-bit words and produce 384 and 512 bits respectively (96 and 128 hex chars). SHA-512 is generally faster on 64-bit CPUs and offers the largest security margin.
