Introduction

Dynamsoft Dynamic Web TWAIN (DWT) is a software development kit (SDK) that enables users to scan and upload documents from a web environment. DWT handles the whole data flow, from image acquisition at the scanner, to displaying and editing scanned images in the browser, and finally uploading to the server.

Here we provide a series of usage guides, so that you can quickly start making use of both basic and advanced features of DWT with just a few lines of code - see our general usage and extended usage guides for more. You can also use our Hello World demo that demonstrates how to enable basic scanning, viewing, and uploading functionality in a web application.

DWT add-ons provide additional features such as scanning using a webcam video feed, document barcode reading, and PDF rasterization.

We also have an API reference where you can find more comprehensive descriptions of our product.
