Document Processing
January 14, 2024
Learn advanced PDF optimization techniques to dramatically reduce file sizes while maintaining document quality. Perfect for web publishing and email distribution.
PDF files can quickly become bloated with high-resolution images, embedded fonts, and unnecessary metadata. This guide shows you how to optimize PDFs for web delivery and email distribution.
Understanding PDF File Structure
PDFs contain multiple components that affect file size:
- Images: Often the largest component
- Fonts: Can be embedded or referenced
- Vector graphics: Scalable but can be complex
- Metadata: Document information and properties
- Compression: Various algorithms for different content
Image Optimization Strategies
Choose appropriate DPI settings based on use case:
- 72-96 DPI: Web viewing, email
- 150 DPI: Office printing, presentations
- 200-250 DPI: High-quality printing
- 300+ DPI: Professional printing, archival
Font Optimization
Reduce font-related bloat:
- Subset fonts to include only used characters
- Use common system fonts when possible
- Convert text to outlines for small amounts
- Embed only necessary font variants
