Conversion Methods

Quality Settings

DPI determines image-to-page scaling. At 72 DPI, a 1920x1080 image fills 26.7 x 15 inches; at 300 DPI, it fits 6.4 x 3.6 inches. 150-200 DPI balances size and quality for most documents. Compression: high quality for portfolios, medium for sharing (50-70% smaller with minimal loss), low for web-only viewing.

Batch Conversion

Two approaches: all images into one multi-page PDF (document scans) or each image as individual PDF (filing). Sort by filename or date before conversion for correct page order.

Mobile Methods

iOS: Files app β†’ select photos β†’ Share β†’ Print β†’ pinch-to-zoom preview creates PDF. Android: Gallery β†’ Share β†’ Print β†’ Save as PDF. Scanner apps (Adobe Scan, Microsoft Lens) capture with perspective correction and export directly.
