Barcode and QR Code Scanner SDK for Web
Enable real-time localization and decoding in a web browser on a mobile or laptop. Transform any camera-equipped devices into barcode and QR code scanners with just a few lines of JavaScript code.
Exceptional Recognition Rate and Accuracy
Highest industry-leading accuracy with an enterprise-grade barcode detection algorithm, OCR capabilities, and the addition of camera enhancing functionality.
Unmatched Speed When Decoding From Video Streams
Scans 500+ barcodes per minute and achieves unbeatable decoding speed much higher than the 2nd best in the industry.
A Full-Capability Barcode Web SDK
Supports barcode and QR code scanning from any image files, captured images, or scanning in real-time. 200+ APIs cater to every possible scenario.
Integrate Barcode And QR Code Scanning In A Web Application
Highly Customizable to Fit Different User Scenarios
Dynamsoft’s barcode web SDK comes with 200+ APIs to optimize in the stages of image pre-processing, localization, recognition, result display, and more.
Built-in Control over Cameras
The built-in camera control via MediaDevices allows users to manipulate the camera functions just like in an native camera app.
Rich UI Elements
An interactive UI that guides the users to aim at the barcodes and highlights the areas where barcodes are found for a better scanning experience.
Scan Linear Barcode and QR Codes at Once
Supports localization and decoding of multiple barcodes and 2D codes at once. The speed is only a fraction slower than when decoding one barcode.
Optimized for QR and DataMatrix Codes
Utilizes sophisticated techniques to decode challenging QR codes and DataMatrix, such as wrinkled, glared, border-missing, or stained.
Decode from Images and Video Streams
Supports decoding barcodes from various inputs, including images, base64 strings, raw image data, and most importantly, video streams.
