This skill provides comprehensive guidance for using pdf-to-pptx-tool, a professional CLI tool that converts PDF documents into PowerPoint presentations. Each PDF page becomes a high-quality slide with customizable resolution.
When to Use This Skill
Use this skill when:
-
You need to convert PDF documents to PowerPoint format
-
You want to customize conversion quality (DPI settings)
-
You need to debug conversion issues with verbose logging

convert - Convert PDF to PowerPoint
Converts a PDF document to PowerPoint format, creating one slide per PDF page with customizable quality settings.
Usage:
pdf-to-pptx-tool convert INPUT_PDF OUTPUT_PPTX [OPTIONS]
Arguments:
INPUT_PDF: Path to input PDF file (required)
Must exist and be a valid PDF file

Supports any PDF version
-
No size limit (memory permitting)
-
OUTPUT_PPTX: Path to output PowerPoint file (required)
Will be created or overwritten

-vvv: TRACE level (library internals)
Examples:
# Example 1: Basic conversion (default 200 DPI)
pdf-to-pptx-tool convert quarterly-report.pdf q4-presentation.pptx
# Example 2: High quality for detailed diagrams
pdf-to-pptx-tool convert technical-diagram.pdf slides.pptx --dpi 300
# Example 3: Lower quality for quick preview

completion - Generate shell completion scripts
Generates shell completion scripts for bash, zsh, or fish shells.
Usage:
pdf-to-pptx-tool completion SHELL
Arguments:
SHELL: Shell type (required)
Options: bash, zsh, fish
- Case-insensitive
Examples:
# Generate bash completion
eval "$(pdf-to-pptx-tool completion bash)"
# Generate zsh completion
eval "$(pdf-to-pptx-tool completion zsh)"
# Generate fish completion
pdf-to-pptx-tool completion fish | source
# Save to file for permanent installation
pdf-to-pptx-tool completion bash > ~/.pdf-to-pptx-tool-completion.bash
echo 'source ~/.pdf-to-pptx-tool-completion.bash' >> ~/.bashrc
Output: Shell-specific completion script printed to stdout.
Multi-Level Verbosity Logging
The tool supports progressive verbosity levels for debugging and monitoring conversions.
Logging Levels:
| (none) | WARNING | Errors/warnings only | Production, quiet mode
| -v
| INFO
| + Operations, progress
| Normal debugging
| -vv
| DEBUG
| + Detailed steps, file sizes
| Development, troubleshooting
| -vvv
| TRACE
| + Library internals (pdf2image, PIL, pptx)
| Deep debugging
Examples:
# Quiet mode - only see errors
pdf-to-pptx-tool convert input.pdf output.pptx
# INFO - see conversion progress
pdf-to-pptx-tool -v convert input.pdf output.pptx
# Output:
# [INFO] Starting PDF to PPTX conversion
# [INFO] Converting input.pdf to output.pptx (DPI: 200)
# [INFO] Converting PDF pages to images...
# [INFO] Converted 5 pages
# [INFO] Creating PowerPoint presentation...
# [INFO] Saving presentation to output.pptx
# DEBUG - see detailed processing
pdf-to-pptx-tool -vv convert input.pdf output.pptx
# Additional output:
# [DEBUG] Input: input.pdf, Output: output.pptx, DPI: 200
# [DEBUG] Validating input file: input.pdf
# [DEBUG] Input file size: 2.45 MB
# [DEBUG] Using DPI setting: 200
# [DEBUG] Processing slide 1/5
# [DEBUG] Output file size: 8.23 MB
# TRACE - see library internals
pdf-to-pptx-tool -vvv convert input.pdf output.pptx
# Shows pdf2image, PIL, and pptx library debug messages
DPI Quality Guidelines
Choose DPI based on your use case:
| 72 | Low | Smallest | Quick previews, draft slides
| 150 | Medium | Small | Web presentations, email
| 200 | Good | Medium | Default - recommended for most
| 300 | High | Large | Print quality, detailed diagrams
| 600 | Very High | Very Large | Professional print, posters
Trade-offs:
-
Higher DPI: Better quality, larger file size, slower conversion
-
Lower DPI: Faster conversion, smaller files, lower quality
-
Sweet spot: 200-300 DPI for most presentations
Batch Processing
Process multiple PDFs efficiently:
# Convert all PDFs in directory
for pdf in *.pdf; do
echo "Converting $pdf..."
pdf-to-pptx-tool convert "$pdf" "${pdf%.pdf}.pptx"
done
# With custom DPI
for pdf in *.pdf; do
pdf-to-pptx-tool convert "$pdf" "${pdf%.pdf}.pptx" --dpi 300
done
# With error handling
for pdf in *.pdf; do
if pdf-to-pptx-tool -v convert "$pdf" "${pdf%.pdf}.pptx"; then
echo "✓ Converted $pdf"
else
echo "✗ Failed to convert $pdf"
fi
done
Shell Completion
Enable tab completion for faster usage:
# Bash - add to ~/.bashrc
eval "$(pdf-to-pptx-tool completion bash)"
# Zsh - add to ~/.zshrc
eval "$(pdf-to-pptx-tool completion zsh)"
# Fish - save to completions directory
mkdir -p ~/.config/fish/completions
pdf-to-pptx-tool completion fish > ~/.config/fish/completions/pdf-to-pptx-tool.fish
Benefits:
-
Tab-complete commands:
pdf-to-pptx-tool <TAB> -
Tab-complete options:
pdf-to-pptx-tool convert --<TAB> -
Tab-complete file paths automatically
Common Issues
Issue: "poppler not found" or PDF conversion fails
# Symptom
RuntimeError: Failed to convert PDF pages: poppler not found
Solution: Install poppler system library:
# macOS
brew install poppler
# Ubuntu/Debian
sudo apt-get install poppler-utils
# Fedora
sudo dnf install poppler-utils
# Verify installation
pdftoppm -v
Issue: "File not found" error
# Symptom
✗ Error: Input PDF file not found: document.pdf
Solution:
-
Verify file path is correct
-
Use absolute paths if needed
-
Check file permissions
# Check file exists
ls -l document.pdf
# Use absolute path
pdf-to-pptx-tool convert /full/path/to/document.pdf output.pptx
Issue: Output file is too large
# Symptom
Generated 50MB PPTX from 2MB PDF
Solution: Reduce DPI setting:
# Try lower DPI
pdf-to-pptx-tool convert input.pdf output.pptx --dpi 150
# Or use default 200 DPI
pdf-to-pptx-tool convert input.pdf output.pptx
Issue: Images look blurry in PowerPoint
# Symptom
Text and diagrams appear pixelated
Solution: Increase DPI setting:
# Use higher quality
pdf-to-pptx-tool convert input.pdf output.pptx --dpi 300
# For print quality
pdf-to-pptx-tool convert input.pdf output.pptx --dpi 600
Issue: Conversion is very slow
# Symptom
Large PDF takes minutes to convert
Solution:
- Use DEBUG logging to see progress:
pdf-to-pptx-tool -vv convert large.pdf output.pptx
- Consider lower DPI for faster conversion:
pdf-to-pptx-tool convert large.pdf output.pptx --dpi 150
- Split large PDF into chunks and convert separately
Issue: Permission denied writing output file
# Symptom
PermissionError: [Errno 13] Permission denied: 'output.pptx'
Solution:
-
Check directory write permissions
-
Use different output location
# Write to home directory
pdf-to-pptx-tool convert input.pdf ~/output.pptx
# Or create directory first
mkdir -p output-dir
pdf-to-pptx-tool convert input.pdf output-dir/output.pptx

Debug Workflow
When conversion fails, use this debugging workflow:
# 1. Check file exists and is readable
ls -lh document.pdf
file document.pdf
# 2. Verify poppler is installed
pdftoppm -v
# 3. Try with DEBUG logging
pdf-to-pptx-tool -vv convert document.pdf test.pptx
# 4. Try with lower DPI if memory issues
pdf-to-pptx-tool -vv convert document.pdf test.pptx --dpi 150
# 5. Check Python and dependencies
python --version
pdf-to-pptx-tool --version

Best Practices
-
Start with default DPI (200): Good balance of quality and file size
-
Use verbose logging for debugging:
-vvshows detailed conversion steps -
Test with sample PDFs first: Verify quality before batch processing
-
Monitor output file sizes: Adjust DPI if files are too large
-
Batch process efficiently: Use shell loops for multiple files
-
Enable shell completion: Speeds up command-line usage
-
Keep poppler updated: Ensures compatibility with latest PDF features
-
Use absolute paths: Avoids confusion with relative paths
-
Verify prerequisites: Check poppler installation before bulk conversions
-
Handle errors gracefully: Check exit codes in scripts
