Preserving Formatting & Quality
✅ Best Practices

- ✗Using low-quality compression settings
- ✗Not testing hyperlinks after merging
💡 Pro Tip: Handling Different Page Sizes
When merging PDFs with different page sizes (e.g., A4 and Letter), most tools will preserve the original sizes. For professional documents, consider converting all files to the same page size before merging to ensure consistency.
Advanced Page Management
Selective Page Merging
Sometimes you don't need to merge entire documents. Here's how to extract and combine specific pages:
Page Range Examples:
- Pages 1-5: Extract first five pages
- Pages 2,4,6: Extract specific non-consecutive pages
- Pages 10-end: Extract from page 10 to the last page
- Pages 1,3-7,10: Mix single pages and ranges
Bookmark Management
📚 Automatic Bookmarks
When merging PDFs, the tool can automatically create bookmarks for each source document, making navigation easier in the final merged file.
🏷️ Custom Bookmarks
Add custom bookmark titles for each section, making your merged PDF more professional and easier to navigate for readers.
Common Issues & Solutions
🔒 Password-Protected PDFs
Problem: Cannot merge PDFs that are password-protected or have restrictions.
Solution: Remove password protection first using a PDF unlock tool, then proceed with merging. Ensure you have permission to modify these documents.
📄 Large File Sizes
Problem: Merged PDF becomes too large to share or upload.
Solution: Use compression settings during merge, or compress the final merged PDF. Consider splitting large documents into smaller sections.
🖼️ Image Quality Loss
Problem: Images appear blurry or pixelated in the merged PDF.
Solution: Use high-quality merge settings and avoid aggressive compression. Ensure source PDFs have good image quality before merging.
🔗 Broken Hyperlinks
Problem: Internal links between pages no longer work after merging.
Solution: Use advanced merge tools that preserve internal link structure, or manually recreate important links after merging.
