Scan to PDF: Scan Multiple Pages in a Batch and Save as PDF

As document scanning experts, we get these question a lot:

  • Is document scanning from within a browser possible? If so, how?
  • How do I save the scanned images as a multi-page PDF file?
  • How do I automatically separate different files in one batch?

We’ll try to answer these questions. Before we provide the solution, we recommend you first give this web demo a try.

Scan multi-pages to PDF Online Demo

The demo application enables users to scan documents from TWAIN scanners and MFPs (Multi-Function Printer). They can save them as PDF files, either one-page PDF or multi-page PDF. Also, it utilizes barcodes as batch separators. If there is a barcode detected on the page, a new file will be created with the barcode value being the filename.

How to Use this Demo

Upon your first visit, the page prompts a message asking you to download and install Dynamic Web TWAIN, which this application is built upon. Dynamic Web TWAIN is a browser-based document scanning and webcam capture SDK. After automated installation, everything should be quite straightforward.

Learn about Scanner Protocols

As a developer, to interact with a scanner from software, you need to understand the scanner driver protocals. There are several protocols on the market: TWAIN, WIA, SANE, ISIS. TWAIN has the biggest market share. The majority of scanners on the market provide a TWAIN driver. For a more detailed comparison, check out the article TWAIN vs. WIA vs. SANE vs. ISIS.

Scan Documents to PDF in a Web Application

Scanners are peripherals devices so they cannot be accessed directly from a browser. You need a browser plugin/extension/windows service to access scanners in Chrome and Firefox, IE and Edge. There is immense complexity in browser compatibility with the TWAIN protocol. So, it’s near impossible to build a browser-based document scanning module from scratch within a reasonable time frame.

Fortunately, Dynamic Web TWAIN can relieve a developer from the trouble. Having evolved for 15 years, Dynamic Web TWAIN provides all the features you need including:

  • Customizable scan settings
  • Image capture from web cameras
  • Loading local image files, image editing
  • Saving scanned images to local drives or uploading them to a remote web server.

Furthermore, multiple imaging add-ons are available, including a barcode reader we used in the demo application. Learn more about web server and programming language support on Dynamic Web TWAIN overview
