      • Easy to distribute: absolutely no supporting DLL needed for distribution.

    Dynamic Web TWAIN Structure Diagram
  • Improved customer experience
    • ActiveX Edition digitally signed by VeriSign.
    • Reduced web page load time. The size of the distribution file is only 197k, and only takes seconds to be downloaded and installed.
    • Reduced image upload time. Dynamic Wed TWAIN supports major compression methods including JPEG, TIFF, PDF and PNG.
    • Improved customer confidence. Absolutely no local file operations required.
    • Supports downloading and uploading via SSL channel.
    • Proxy connections supported, no need for customers to reconfigure their firewalls.
  • Save time and money
    • Greatly reduced development time. The TWAIN 1.9 specification alone is 552 pages long. How many days will it take you simply to read it, let alone build a TWAIN compatible application with it? If compression support is required, it could take months. With Dynamic Web TWAIN, most applications can implement TWAIN support with no more than a few lines of code.
    • Even greater time savings. By tapping into Dynamsoft's TWAIN knowledge base via our Virtual Developer Service, the total time needed to build your scanning solution could be reduced from several months to several hours.
  • Other benefits
    • Improved product quality
    • Speeded up product delivery
