Advanced Merging Tips
📊 Merging Large Files
For very large PDFs (100+ pages), consider:
- • Merging in smaller batches first
- • Compressing individual files before merging
- • Using a desktop tool for better performance
🔒 Merging Secured PDFs
Password-protected PDFs require:
- • Removing protection first (if you have permission)
- • Using tools that support encrypted files
- • Re-applying security after merging
🎯 Pro Tip: Organize Then Merge
If you need to merge specific pages from different documents, first use the "Extract Pages" feature to pull out the pages you need, then merge those extracted files.
Common Issues & Solutions
❓ Merged file is too large
Solution: Use the PDF Compressor tool after merging to reduce file size while maintaining quality.
❓ Pages appear in wrong order
Solution: Carefully arrange files using the arrow buttons before clicking merge. Preview the order in the file list.
❓ Some fonts look different
Solution: Ensure source PDFs have embedded fonts. You can use PDF/A format for better font compatibility.
