How does in-browser camera scanning work?

The tool uses the standard HTML5 MediaDevices API to stream your webcam or phone camera video directly into a local canvas element. When you tap the shutter, a high-resolution frame is captured and filtered locally in memory without transmitting any image data to external servers.

What does the Magic B&W Document filter do?

The Magic B&W filter applies adaptive contrast stretching and paper thresholding. It automatically whitens grayish shadows and yellow paper backgrounds while sharpening black text, creating a clean document photocopy look.

Can I combine multiple photos or camera snaps into one PDF?

Yes. You can capture multiple pages using your camera, upload additional photos, rearrange page sequence, rotate sideways pages, and compile them all into a single unified multi-page PDF.

Is my camera feed or document photo stored anywhere?

No. All camera frames and image buffers remain strictly in your computer's local RAM. No server uploads, tracking, or external image processing occur at any stage.
