Scan to PDF
Capture, auto-crop, enhance, rotate, and merge document photos into one polished PDF.
A practical guide to Scan to PDF
Document Scanner captures camera frames or uploaded photos, detects page edges, corrects perspective, applies scan filters, arranges pages, and exports one PDF locally.
Example: scan a signed receipt packet
Capture each page squarely, correct corners, retain color for signatures, arrange the sequence, and inspect small totals in the PDF.
Task-specific steps
- 1
Grant camera access or add photos, then capture each page in even light with all corners visible.
- 2
Correct the page boundary, rotation, brightness, contrast, and scan filter while checking fine text and stamps.
- 3
Arrange pages, choose export quality, build the PDF, and inspect every page before discarding paper originals.
Options that affect the result
- Enhanced, color, grayscale, and black-and-white filters suit different paper, stamp, and text needs.
- Perspective correction and page actions turn angled captures into an ordered document.
Limitations to know first
- Glare, blur, folds, curved pages, shadows, and low camera resolution cannot always be corrected after capture.
- A scanned PDF contains page images until OCR adds a searchable text layer.
Questions specific to this task
Which scan filter should I use?
Use color for stamps and signatures, enhanced or grayscale for general documents, and black-and-white only when high contrast does not erase detail.
Why are page edges detected incorrectly?
The background may lack contrast or shadows may resemble edges. Reposition the page or adjust the corners manually.
