Upload a QR/barcode image or tap "Live Camera". Our engine powered by ZXing library extracts any text, URL, or WiFi credentials instantly — no app install.
Screenshot the WiFi share QR from your Android device → upload here → get SSID + password revealed. Never lose network access again.
Supports 20+ formats: QR, Data Matrix, Aztec, PDF417, EAN, UPC, Code128, and more. All processing stays on your device, respecting your privacy.
ZXing Org is the most reliable alternative to zxing.org with modern interface and WiFi QR password extraction. Whether you need to read a product barcode, recover a WiFi password from a QR code screenshot, or scan a boarding pass, our tool delivers instant results.
Unlike other tools, ZXing Org never sends your images to any server. Decoding is done locally via JavaScript: your sensitive WiFi passwords or personal QR codes remain completely private.
If your phone fails to auto-connect, simply use our decoder to reveal the plain-text password. Then manually join the network — easy and foolproof.
ZXing Org is the most reliable alternative to traditional barcode scanners, offering a modern, fast, and completely free QR code and barcode decoding solution. Whether you need to read a product barcode, recover a WiFi password from a QR code screenshot, scan a boarding pass, or decode a complex Data Matrix on industrial equipment, our tool delivers instant results directly in your browser — with zero data uploads and maximum privacy.
The ZXing (Zebra Crossing) open-source library powers our decoder, giving you enterprise-grade scanning capabilities. Unlike many online tools that only read basic QR codes, ZXing Org supports a vast range of formats including:
From retail products (UPC/EAN) to logistics (Code 128, ITF) and marketing campaigns (QR, Data Matrix), ZXing Org handles everything. No configuration needed — just upload or point your camera.
Unlike most online QR scanners that upload your images to remote servers for processing, ZXing Org works entirely in your browser. When you select an image or use your live camera, the ZXing JavaScript library scans the barcode locally on your device. No images are ever transmitted across the internet, no temporary copies are stored on external servers, and no one — not even us — can access your scanned content. This is especially critical when decoding sensitive information like WiFi credentials, personal identification numbers, payment QR codes, or confidential business barcodes. With ZXing Org, what you scan stays on your device, period.
One of the most popular and powerful features of ZXing Org is the ability to reveal hidden WiFi passwords from QR code screenshots. Here's how it works: On most Android devices, when you tap "Share" on a connected WiFi network, the system generates a QR code containing the network name (SSID) and password in a standardized format (WIFI:S:network_name;T:WPA;P:your_password;;). By taking a screenshot of that QR code and uploading it to ZXing Org, our decoder automatically detects the WiFi schema and presents you with both the SSID and the plain-text password. This is incredibly useful when:
ZXing Org displays the extracted password in a large, bold, copyable format, making it easy to paste into any WiFi connection screen. This feature alone has helped thousands of users regain access to their networks without resetting routers or calling ISPs.
ZXing Org is built with a mobile-first responsive design, ensuring a seamless experience on smartphones and tablets. Use the live camera scanner to decode QR codes in real-time — just point your phone's camera at any barcode, and the result appears instantly. Or, use the upload feature to decode screenshots or saved images from your gallery. Unlike native apps that require installation and permissions, ZXing Org works immediately in Chrome, Safari, Firefox, and Edge on both Android and iOS. No app store, no updates, no storage waste — just pure web-based convenience.
There are dozens of "free" QR code readers online, but most come with hidden drawbacks: image uploads to unknown servers, aggressive watermarks, daily scan limits, or intrusive ads that break usability. ZXing Org is different:
Personal: Decode QR codes on product packaging to access nutritional info, scan WiFi QR codes at coffee shops or hotels, extract data from event tickets, or share contact information (vCard QR codes).
Business & Logistics: Scan Code 128 or PDF417 barcodes on shipping labels, track inventory with UPC/EAN codes, decode Data Matrix on electronic components, or verify batch numbers using ITF barcodes.
Education & Research: Students and researchers can decode QR codes embedded in academic papers, museum exhibits, or interactive learning materials without installing specialized apps.
Accessibility: Individuals with visual impairments can use ZXing Org with screen readers to extract text from QR codes that might otherwise be inaccessible.
To get the best decoding results, follow these simple guidelines:
ZXing Org's decoder is tolerant of minor distortions, angle variations, and even some damage to barcodes, but optimal image quality yields the fastest and most reliable results.
We take security seriously. Because ZXing Org processes everything on your local device, there is no risk of data interception during transmission, no server-side logging of your images, and no database of scanned barcodes. The only data stored locally is your WiFi decoding history (if you choose to keep it), and that data never leaves your browser's local storage. You can clear it anytime from your browser settings. Advertisements displayed on the site are served by Google AdSense, which may use cookies for personalized ads — but these ads never interact with your decoded content. For complete details, refer to our Privacy Policy in the footer.
Does ZXing Org work offline? After the initial page load, the core decoder works without an internet connection because all scripts are cached in your browser. However, you will need a connection to load the page initially and for ads/analytics.
Can I decode barcodes from PDF files? Currently, ZXing Org works with common image formats (JPG, PNG, WebP, GIF). To decode from a PDF, you can take a screenshot of the barcode page and upload that image.
Is there an API for developers? At this time, ZXing Org is a free web tool without a public API. However, since it uses the open-source ZXing library, developers can integrate the same functionality into their own projects using the @zxing/library npm package.
Why does the camera scanner sometimes not detect codes? Ensure you have granted camera permissions to your browser. Additionally, some low-resolution webcams may struggle with very small barcodes; try enlarging the code or moving the camera closer.
Can ZXing Org generate QR codes? This tool is focused on decoding only. For QR code generation, we recommend using any of the many free QR code generators available online.
How accurate is the decoder for damaged or dirty barcodes? The ZXing library includes error correction capabilities (especially for QR codes, which have Reed-Solomon error correction). Minor damage, dirt, or creative overlays are often still decodable. However, severely damaged codes may fail.
ZXing Org combines the robust decoding power of the open-source ZXing project with a modern, ad-supported free model that prioritizes user privacy and ease of use. Whether you're a casual user needing to quickly scan a QR code, a network administrator recovering WiFi credentials, or a logistics professional verifying barcodes, ZXing Org delivers speed, accuracy, and complete confidentiality.
