In their own words
Dynamic Web TWAIN
Dynamic Web TWAIN is a browser-based document-scanning SDK for web applications that 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. Scanned pages can be exported as PDF, TIFF, JPEG, PNG, or BMP, including multi-page PDF and TIFF files. The built-in viewer and editor provide annotation, zoom, deskew, and rotation. Disk caching supports unlimited pages per session, and a 64-bit service mode is available for large data. Supported client systems include Windows 7 or later, macOS 10.15 or later, and Linux distributions for x64, ARM64, or MIPS. Listed browsers include Chrome, Firefox, and Edge on Windows and Linux, and Safari on macOS. The SDK 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 gives full SDK access without feature restrictions and requires no credit card. Pricing is available on request; there is no free plan. PDF Rasterizer, Barcode Reader, OCR, and Webcam add-ons are licensed separately.
