Combine multiple PDF files into a single document. Arrange pages, preserve quality, and merge PDFs instantly.
You can merge unlimited PDF files, but for best performance:
• Recommended: Up to 50 files per merge
• Maximum total size: 100MB
• Very large collections may take longer
• For 100+ files, consider merging in batches
There's no hard limit on file count, only size restrictions.
Yes! Our merger preserves original quality by default:
• Images remain at original resolution
• Text stays crisp and clear
• Vector graphics remain sharp
• Form fields and links are preserved
• Only compression if explicitly enabled
The output PDF will match the best input quality.
Our tool merges entire PDF files in the order you arrange them. For page-level control:
1. Files are merged in the order shown in the list
2. Drag and drop to rearrange file order
3. Each file's pages remain in original order
For page-level rearrangement, consider splitting PDFs first, then merging in desired order.
Bookmarks and links are preserved intelligently:
✅ Internal links within each PDF continue to work
✅ Bookmarks from each PDF are combined
✅ You can choose to add new bookmarks for each file
✅ Hyperlinks to external websites remain active
✅ Table of contents entries are preserved
Enable "Add bookmarks" option for best results.
Password-protected PDFs require decryption first:
• Remove passwords before uploading
• Most PDF editors can save unprotected versions
• Our tool doesn't support encrypted PDFs for security
• Merge only unencrypted PDF files
For confidential documents, process them offline first.
We recommend these size guidelines:
• Individual files: Up to 50MB each
• Total batch: Up to 100MB combined
• For larger files: 100-200MB may work but slower
• Over 200MB: Consider compressing first
• Very large PDFs: Split into smaller parts first
Performance depends on your device's memory.
