- Grayscale Document: Preserves tonal information with smaller file sizes
- Photograph: Uses higher DPI (600+) for detailed image reproduction
Configure your PDF file
You can customize advanced settings by clicking the gear icon:
- Resolution (DPI): Higher DPI means better quality but larger files
- Paper Size: Choose standard sizes or custom dimensions
- Scanning Sides: Single-sided or double-sided scanning
- File Format: PDF, JPEG, or other supported formats
- Compression: Balance file size and quality effectively
Click the Scan button to begin. For multiple pages, Adobe Acrobat prompts after each page whether to scan more pages or complete the process. This workflow is similar to batch processing PDFs programmatically.
What Happens After I Complete the Scanning Process?
Following these steps, you'll scan all pages and convert them into one PDF file. After scanning, Adobe Acrobat provides several post-processing options that enhance your documents:
- Enhance Scans: Automatically improves text clarity and removes backgrounds
- Recognize Text (OCR): Makes scanned text searchable and selectable
- Organize Pages: Add, delete, or reorder pages as needed
- Rotate Pages: Correct pages scanned in wrong orientation
Scanning multiple pages creates comprehensive PDFs with more data. The combined PDF can be optimized for different purposes, whether for web distribution, archival storage, or printing. You can also add metadata for better document organization, apply security settings, or create PDF/A compliant files for long-term preservation.
