Free Online Document Scanner — Scan to PDF in Your Browser

Q: What is an online scanner and how does it work?

An online document scanner is a browser-based tool that uses your device's camera or uploaded photos to digitize paper documents. Using computer vision algorithms (homography perspective transformation and adaptive binarization), it detects edges, flattens tilted angles, enhances text contrast, and exports multi-page PDFs directly on your device without server uploads.

Q: Is Scanner.cam a free CamScanner alternative without watermark?

Yes. Scanner.cam is a 100% free web alternative to mobile CamScanner. It does not add any watermarks, does not require account signup or app store downloads, and allows unlimited multi-page PDF exports.

Q: Are my scanned documents private and secure?

Yes, absolutely. Unlike traditional mobile scanning apps that upload your sensitive documents, contracts, and IDs to cloud servers, Scanner.cam executes all image processing locally in your browser using client-side Web Workers. Your images never leave your device.

Q: How can I avoid shadows in my scans?

Use even, diffused light and avoid casting shadows over the page. Then apply the Magic Color filter, which evens out uneven room lighting and finger shadows, or Clean B/W for crisp printed text.

Scanner.cam is a 100% free, private online document scanner and CamScanner web alternative. Turn your phone camera or webcam into a high-precision document digitizer: straighten skewed angles, remove shadows, and export clean multi-page PDFs — with zero server uploads, no watermarks, and no account signup.

No app install: works instantly in any desktop or mobile browser (iOS Safari, Android Chrome, Edge, Firefox).
Flatbed-grade quality: 8-parameter homography perspective correction and Sauvola adaptive thresholding for crisp, shadow-free scans.
