PDF files can quickly become unwieldy. At RevisePDF, we've built a compression tool that significantly reduces file sizes while maintaining quality.
Our Technical Stack
- Python/Flask for the web application
- PyMuPDF for PDF analysis
- Ghostscript for compression
- Supabase for authentication
The Compression Pipeline
-
File Upload and Validation
- Secure handling with size checks
- Virus scanning
-
PDF Analysis
- Analysing PDF structure
- Determining optimal compression strategy
-
Compression Processing
- Applying optimised parameters
- Downsampling images appropriately
Key Challenges We Solved
- Preserving Text Quality: Using different settings for text vs images
- Handling Large Files: Implementing asynchronous processing
- Balancing Size vs Quality: Creating multiple compression presets
Results
Typical compression rates range from 65-75% reduction in file size!
