Document Scanner

Scan documents with your phone or webcam, clean them up, and export to PDF, JPG or PNG.

How to use

1. Tap “Start camera”, allow camera access, frame the document, and capture the page.
2. The scanner uses the camera’s high-resolution still-photo path when available, then automatically flattens a reliably detected page.
3. Use Detect edges to repeat boundary detection and perspective correction.
4. Use Deskew, Crop and Rotate when you want to adjust the page manually.
5. Fine-tune with rotate, crop, filters and brightness/contrast.
6. Export all pages to PDF, or single pages to JPG/PNG.

Features

• High-resolution back-camera capture with continuous autofocus where supported
• Best-effort boundary detection and perspective deskew
• Original colour image retained when no reliable boundary is found
• Perspective deskew for angled shots
• Grayscale, black-and-white and enhance filters
• Multi-page export to PDF, JPG or PNG

Good to know

• Camera access needs a secure page (HTTPS) or localhost, and the browser’s permission.
• Edge detection works best when the paper contrasts with the surface behind it.
