Key Concepts You Need to Know

  • Font embedding prevents text substitution and layout shifts
  • Image resolution should match the output medium (72 DPI for web, 300+ for print)
  • Linearized PDFs (Fast Web View) load progressively for better web performance
  • Tagged PDFs enable screen reader accessibility and WCAG compliance
  • Cross-viewer testing ensures consistent rendering across all platforms

Tips & Best Practices

Always embed fonts to ensure consistent rendering across all viewers

Test PDFs on multiple devices, browsers, and operating systems

Use PDF/A for long-term archival to ensure future compatibility

Optimize for web with linearization for faster online viewing

Create a quality checklist specific to your document type

Avoid These Common Pitfalls
  • Not embedding fonts causes text substitution on different systems
  • Using too-high image resolution wastes space without quality benefit
  • Not linearizing PDFs for web causes slow loading and poor user experience
  • Skipping accessibility tags excludes users who rely on screen readers
  • Not testing across viewers leads to inconsistent rendering

Embed all fonts, use standard color spaces, test across multiple viewers (Acrobat, browsers, mobile), and avoid features that aren't universally supported.
For web viewing, 72-150 DPI is sufficient. For print, use 300 DPI minimum. Higher resolutions increase file size without visible quality improvement.
Linearize (Fast Web View) your PDFs, compress images, reduce file size, and use progressive loading. PDFly's compression tool automatically optimizes for web viewing.
Accessible PDFs have proper tags, reading order, alternative text for images, sufficient color contrast, and keyboard navigation support. Follow WCAG 2.1 guidelines for best results.
