Chapter 1: Understanding PPT File Size

Why Files Become Large

PowerPoint presentations accumulate size through various elements:

Understanding causes enables effective solutions

File Size Benchmarks

Chapter 2: Image Compression

Understanding Image Compression

Images typically offer the greatest compression opportunity. Understanding how image compression works helps you make better decisions.

Key Concepts:

• Resolution: Pixels per inch (PPI)
• Dimensions: Width x height in pixels
• Format: How image data is stored
• Compression: Reducing file size by removing data

Image Compression Methods

Method 1: Built-in Compression

Steps:

1. Click any image in your presentation
2. Go to Picture Format > Compress Pictures
3. Uncheck “Apply only to this picture” for batch
4. Select resolution target
5. Click OK

Method 2: Pre-insertion Optimization

Steps:

1. Optimize images before inserting
2. Use appropriate format (JPEG for photos, PNG for graphics)
3. Resize to match display size
4. Insert optimized image

Chapter 3: Video Optimization

Video Compression Strategies

Video requires special handling due to its size potential.

Strategy 1: Compress and Embed

• Best for: Essential video content
• Process: Reduce file size while maintaining acceptable quality
• Tools: HandBrake, FFmpeg, built-in PowerPoint compression

Strategy 2: Link Externally

• Best for: Large video files, presentations with internet access
• Process: Host video externally, link from presentation
• Benefits: Dramatically smaller presentation file

Video Compression Settings

Video Decision Framework

1. Is video essential? → If no, consider removing
2. File size under 10MB? → Keep as-is or light compression
3. File size 10-50MB? → Apply compression
4. File size over 50MB? → Link externally

Chapter 4: Audio Optimization

Audio Compression Basics

Audio files often provide overlooked optimization opportunities.

Key Settings:

• Bitrate: Data rate, affects quality and size
• Sample rate: Audio detail level
• Format: MP3, AAC, WAV

Audio Optimization Settings

Audio Optimization Steps

1. Identify all audio in presentation
2. Determine optimal bitrate for each
3. Export and recompress if needed
4. Replace original with optimized version
5. Verify playback quality

Proper tools enable proper optimization

Chapter 5: Structural Optimization

Cleaning Presentation Structure

Beyond media optimization, presentation structure affects file size.

Areas to Clean:

1. Unused Master Slides

   • Go to View > Slide Master
   • Delete unused layouts
   • Reduces template overhead

2. Hidden Data

   • File > Info > Check for Issues
   • Run Document Inspector
   • Remove unwanted items

3. Cropped Image Areas

   • Select image
   • Compress Pictures
   • Check “Delete cropped areas”

4. Unnecessary Embeddings

   • Review embedded fonts
   • Remove if standard fonts available
   • Review embedded objects

Chapter 6: Tools and Resources

• HandBrake: Video encoding (download)

Chapter 7: Best Practices

Compression Workflow Best Practices

1. Before Starting

   • Create backup of original
   • Assess file composition
   • Set clear size targets

2. During Compression

   • Apply compression systematically
   • Verify quality at each stage
   • Document settings used

3. After Compression

   • Thoroughly test results
   • Verify on target platform
   • Archive both versions appropriately

Quality Preservation Best Practices

1. Match compression to display requirements
2. Preserve quality for critical visual elements
3. Test at actual display size
4. Keep original file until satisfied with results
5. Document successful approaches

Verification ensures quality results

Chapter 8: Troubleshooting

Common Issues and Solutions

Chapter 9: Quick Reference

Compression Setting Quick Guide

IMAGES:
- Email/Web: 96-150 ppi
- Presentation: 150-220 ppi
- Print: 220-330 ppi

VIDEO:
- Keep: < 10MB
- Compress: 10-50MB
- Link: > 50MB

AUDIO:
- Voice: 64-96 kbps
- Music: 128 kbps
- Professional: 192+ kbps

Decision Quick Reference

IF size > target:
  1. Compress images (biggest impact)
  2. Handle video (compress or link)
  3. Optimize audio
  4. Clean structure
  5. Re-verify

IF quality poor:
  1. Identify affected elements
  2. Use lighter compression
  3. Re-apply selectively
  4. Re-verify
