Common PDF Questions Answered
Why can't I merge my PDF files?
If merging isn't working, check that:
- You've uploaded at least 2 PDF files
- All files are valid PDF documents (not corrupted)
- No files are password protected
- Your internet connection is stable
How much can I compress a PDF?
Compression results vary depending on:
- Original file quality and contents
- Images in the document (more images = greater potential reduction)
- Text density and formatting complexity
Typical compression can reduce file size by 30-70% without noticeable quality loss.
Is there a file size limit?
Our web-based tools can handle most standard PDF files. For optimal performance:
- Individual files under 50MB process fastest
- Total merge size under 100MB recommended
- Larger files may take longer but will still process
PDF Best Practices
- Always keep backups of original files before processing
- For sensitive documents, process offline or use secure tools
- Name your files descriptively before merging for better organization
- When compressing, try medium setting first to balance quality/size
Security Note: All file processing happens in your browser - your documents are never uploaded to our servers, ensuring complete privacy.
