Converting PDF to PDF/A for Archival
PDF/A is ISO standard for long-term document archiving, ensuring docs remain readable and visually consistent for decades or centuries. This transforms standard PDFs into fully compliant PDF/A files with embedded fonts, standardized color spaces, proper metadata for permanent preservation.
Prep
Before starting:
- Choose any standard PDF needing long-term preservation
- Works with docs containing text, images, graphics, forms
- Handles PDFs up to 200MB
- Select files needing permanent preservation and accessibility
- Keep original PDFs as backup before archival conversion
Upload
Begin:
- Click "Upload PDF" to select document
- Drag-and-drop supported
- System validates format and begins immediate analysis
- Shows filename, size, basic characteristics after upload
- Option to change file if wrong selection
Understanding PDF/A Standards
Key archival principles:
- Self-contained - all resources (fonts, color profiles) embedded within file
- Device independent - appears identical on all devices and software
- Uncompressed - no lossy compression that could degrade over time
- Metadata structured - proper document info for future identification
- Future-proof - remains readable as technology evolves
Conformance Level
Choose from 8 ISO standards:
- PDF/A-1b (Level B): Basic visual reproducibility - ISO 19005-1
- PDF/A-1a (Level A): Full accessibility with text extraction
- PDF/A-2b (Level B): Enhanced features with JPEG2000 support
- PDF/A-2u (Level U): Unicode text mapping for searchability
- PDF/A-2a (Level A): Complete accessibility with modern features
- PDF/A-3b (Level B): Modern standard with embedded files support
- PDF/A-3u (Level U): Unicode mapping with attachments
- PDF/A-3a (Level A): Premium compliance with all features (Recommended)
PDF Analysis
System examines:
- Page count analysis - determines total pages and complexity
- Content assessment - identifies images, fonts, color spaces, special features
- Compatibility check - verifies elements compatible with PDF/A standards
- Complexity rating - rates as Low, Medium, or High complexity
- Potential issues - detects elements needing conversion or removal
Accessibility Levels
Choose appropriate accessibility:
- Basic (Level B): Visual preservation only, no text extraction
- Unicode (Level U): Text extraction and search capability
- Full (Level A): Complete accessibility for screen readers and assistive tech
- Each level provides different features and compliance requirements
PDF/A Features
During conversion:
- Font embedding - all fonts converted and embedded
- Color space standardization - converted to standardized color profiles
- Metadata compliance - document properties structured per ISO standards
- Transparency flattening - complex transparencies converted to compatible format
- Encryption removal - any security restrictions removed for accessibility
- Tag generation - accessibility tags added for screen readers (Level A)
- Attachment handling - embedded files preserved (PDF/A-3 only)
Industry Recommendations
Based on needs:
- Corporate docs - PDF/A-3b for general business archiving
- Government records - PDF/A-2a or PDF/A-3a for full compliance
- Legal docs - PDF/A-2u for searchable text and Unicode support
- Healthcare records - PDF/A-2a for accessibility and HIPAA compliance
- Educational materials - PDF/A-3b with embedded resources
- Library archives - PDF/A-3a for max preservation
- Enterprise systems - PDF/A-3u for international document exchange
Start Conversion
Generate archival PDF/A:
- Click "Convert to [Selected Standard]"
- Real-time progress bar shows stages
- Status messages indicate current compliance phase
- Processing time depends on PDF complexity and selected standard
- Cancel option available during conversion
Processing Stages
System processes through:
- Validation (0-20%) - analyze PDF structure and identify non-compliant elements
- Processing (20-50%) - apply PDF/A standards and modify document structure
- Compliance (50-80%) - implement all ISO requirements and validations
- Completion (80-100%) - finalize file and prepare for download
- Each stage includes quality checks and error handling
Compliance Validation
Rigorous quality assurance:
- 25 validation checks - comprehensive compliance testing
- Real-time scoring - percentage compliance scores
- Error detection - identify and report any compliance issues
- Warning system - highlight potential problems
- Success criteria - must pass minimum thresholds for each standard
Results
When done:
- ISO certification - clear indication of successful PDF/A conversion
- Processing time - total conversion time in seconds
- Compliance metrics - detailed scores for validation, font embedding, color space, metadata
- File comparison - original vs. PDF/A file size
- Validation summary - number of checks passed vs. total checks
Quality Metrics
Understanding compliance scores:
- Validation score - overall compliance with selected PDF/A standard
- Font embedding - success rate of font conversion and embedding
- Color space - accuracy of color profile standardization
- Metadata - proper structuring of document properties
- All scores shown as percentages

PDF/A (the "A" stands for "Archival") follows ISO standards that guarantee several things: all fonts embedded so text displays correctly even if fonts become unavailable, colors managed consistently, metadata structured properly, file contains no content depending on external resources. Ensures document will look exactly the same when opened 50 years from now as it does today. Supports different PDF/A "conformance levels" (like PDF/A-1b, PDF/A-2b, PDF/A-3b) to match specific archival needs. Essential for legal professionals archiving contracts and court docs, libraries preserving historical materials, government agencies maintaining permanent records, businesses storing important documentation, or anyone with content needing guaranteed long-term accessibility. Conversion process validates PDF against archival standards and makes necessary adjustments, creating file optimized for preservation while maintaining original content and appearance.
