FAQ
ドキュメントスキャン FAQ
ローカルスキャン、四隅補正、プライバシー処理についての短い回答です。
Does it work like a scanner app?
It covers the common scanner workflow: image upload or camera capture, edge cleanup, perspective correction, brightness, and PDF export.
Is OCR included?
No. This tool focuses on making a clean PDF from document photos, not extracting text.
Why are the corner handles transparent?
The handles are designed not to cover the exact document edge while you place the four corners.
Are ID photos safe to process?
The processing happens locally in your browser, so selected images are not uploaded by the tool.
