Photograph each page, adjust the detected frame, then create one PDF for this session.
The app will suggest a page frame automatically. You can drag each corner before the page is added, so you do not have to line up the camera perfectly.
No pages scanned yet.
Document scanner processing is done locally in the browser with no external OpenCV download. Images are reduced to a phone-friendly working size before perspective correction. Text Preserve avoids hard thresholding so fine print remains visible. A warped-original preview is retained beside the processed preview. No OCR is performed.
Frame This Page
Drag the four corner handles to include exactly what should appear in the PDF.
The app starts with an automatic page frame. Adjust any corner that missed the paper edge, then tap Apply Frame.
