Hardware bridge
Connect a scanner from the browser
Request WebUSB/WebHID access and prepare the protocol layer needed for real scanner image capture.
No hardware request yet.
Real scanning requires each scanner vendor's USB endpoint protocol or TWAIN/SANE bridge. Browsers cannot magically speak every scanner protocol without that command map.
User guide
How to use Browser Scanner Connector
Inspect WebUSB/WebHID availability and connect only through a known, documented device protocol adapter.
- 1
Use a supported Chromium browser over HTTPS.
- 2
Choose Connect and select a compatible device in the browser prompt.
- 3
Load the exact vendor/product protocol adapter and request a test status.
- 4
Scan only after endpoint and response validation succeeds.
Best for
- Prototype hardware integrations
- Managed enterprise devices with documented protocols
Important limitation
There is no universal browser scanner protocol. USB/HID access needs user permission, compatible devices, OS/browser support, and vendor-specific commands; arbitrary control transfers can be unsafe.
Frequently asked questions
Is this driverless for every scanner?
No. Each supported model needs a tested protocol adapter.
Does it work on Safari or Firefox?
WebUSB support is limited; check the target browser and platform.
