Aster PDF Tools 앱 분석 (10월 1일)

Aster PDF Tools is a local PDF workspace for everyday document tasks. Import a PDF or image, review it, create a new copy, and keep processing on your device. Key features: - Smart Batch Scan: capture up to 20 pages, review page order, inspect quality, and create a local PDF. - English OCR: add a searchable text layer for English and Latin characters when the quality gate passes. - Local Signing: add a drawn, typed, or image signature and export a separate signed copy. - PDF Password Encryption: create a new PDF protected with AES-256 encryption. - Redact Sensitive Content: mark areas in the preview and export a flattened copy with the original unchanged. - Business Watermark: add text to every page and adjust its opacity before creating a new copy. - PDF viewer: navigate pages, change zoom, and use Highlight, Note, and Underline review tools. - Export and share: save a document as PDF, PNG, or JPG, or open the Android system share sheet. Privacy and boundaries: - Import, scanning, OCR, signing, encryption, redaction, and watermarking are processed on this device. - Imported files use Android system file access. Generated copies stay in app-private storage until you choose to export or share them. - The app does not request camera or media permissions directly. Smart scanning is provided by Google Play services, and gallery or file imports use the Android system picker. - OCR supports English and Latin characters. Documents in other scripts remain image-only and are not advertised as searchable. - Passwords and signatures are never saved. A signature added by this app is a visual PDF mark, not a certified or legal signature. No account or cloud sync is required. You choose what to import, review, secure, export, and share.
