Dynamic Web TWAIN
What Dynamic Web TWAIN is
Dynamic Web TWAIN is a browser-based document scanning SDK that lets web applications control scanners using TWAIN, WIA, ICA, SANE, and eSCL. Scanning runs locally through the Dynamsoft Web TWAIN Service, and document data is not sent to Dynamsoft servers. The SDK exports pages as PDF, TIFF, JPEG, PNG, or BMP, including multi-page PDF and TIFF. Its viewer and editor provide annotation, zoom, deskew, and rotation. Disk caching supports unlimited pages per session, and a 64-bit mode is available for large data. Client operating systems include Windows 7 or later, macOS 10.15 or later, and Linux x64, ARM64, or MIPS distributions. It works with React, Vue, Angular, JavaScript, and TypeScript, with server-side compatibility for Node.js, PHP, ASP.NET, Java, and Python. A 30-day trial provides full SDK access without feature restrictions and needs no credit card. Pricing is on request; there is no free plan.
