Automatic or manual
Detect document boundaries and capture when the frame is stable, while keeping a manual shutter available.
Buyer and developer guide
Browser document scanning SDK for JavaScript
SavyScan adds automatic and manual camera capture, page editing, and multipage PDF output to a web application without sending document pixels to a SavyScan server.
01 / Product fit
When a browser scanner is the right tool
Use a browser document scanning SDK when employees or customers need to capture readable paperwork inside an existing web workflow. SavyScan is designed for purchase orders, packing slips, invoices, receipts, field forms, and other page-shaped documents.
The host application controls authentication, storage, email, and business records. SavyScan controls the camera and page-editing experience, then returns image and PDF Blobs to the host application.
02 / Capabilities
From camera frame to multipage PDF
Correct every page
Adjust corners, correct perspective, rotate, apply enhancement modes, retake, delete, and revisit pages.
Return useful files
Assemble multiple corrected pages into a PDF Blob and return a JPEG preview to the host application.
03 / Compare approaches
SDK, file input, or native application?
| Approach | Best for | Tradeoff |
|---|---|---|
| SavyScan browser SDK | Guided capture embedded in a JavaScript web workflow | Requires HTTPS, camera permission, and validation on target devices |
| Basic file input | Simple uploads with minimal implementation | No consistent live detection, crop, page editor, or capture guidance |
| Native scanning app | Deep operating-system integration | Users leave the web workflow or teams maintain native applications |
| Server-side image processing | Centralized post-upload processing | Document pixels must leave the device before correction |
04 / Privacy boundary
Local processing by default
Captured pages and generated PDFs remain in browser memory until the integrating application explicitly uploads, stores, or emails them. SavyScan licensing and privacy-safe diagnostics do not require document images or PDF contents.
Clear responsibility boundary. The customer application decides where completed files go and is responsible for its own storage, retention, access control, and regulatory requirements.
05 / Compatibility
Tested mobile-browser baseline
The complete capture, crop, rotation, multipage, PDF preview, and email-attachment workflow passed with real documents on iPhone Safari, iPhone Chrome, Samsung Chrome, and iPad Safari during the 0.5.0 beta qualification.
Browser camera behavior varies by device and operating-system release, so every customer should qualify its intended workflow and device mix during the free trial. See the compatibility evidence and requirements.
06 / Evaluation
What to verify during a trial
- Launch SavyScan from the intended HTTPS application and domain.
- Test automatic and manual capture with representative documents.
- Crop, rotate, enhance, retake, delete, and revisit pages.
- Build a multipage document and complete the scan.
- Preview the PDF and deliver it through the real upload or email workflow.
- Repeat on the Apple and Android devices the application supports.
