Verify file order carefully
Drag files into the exact sequence you want - the merge follows the top-to-bottom order shown in the interface.
Use consistent naming conventions
Name source files with clear prefixes or sequential numbers to simplify organization in large projects.
Maintain document structure
Enable bookmark preservation to maintain navigation trees and review the combined table of contents after merging.
Remove unnecessary content
Use page ranges to exclude blank pages, drafts, or irrelevant content before merging to optimize file size.
Add organizational elements
Insert blank pages, dividers, or cover sheets between merged documents for better organization and professional presentation.

PDF Merging FAQ
Can I control the order of merged files?
Yes, you can drag and drop files in the exact order you want them merged, or use filename sorting options for automatic organization.
Are bookmarks preserved during merging?
We attempt to preserve bookmarks from your source files. You can choose to keep existing bookmarks, discard them, or rebuild a combined table of contents.
Can I exclude specific pages before merging?
Yes, you can specify page ranges for each file to include only the relevant pages in your merged output.
Are there file size restrictions?
We support individual PDF files up to 100 MB. For batch processing and large merged documents, size limits may vary based on server capacity.
Can I add cover pages or separators?
Yes, you can insert custom cover pages, dividers, or blank separators at any point in your merge sequence for better organization.
Does merging affect document quality?
No, pages are preserved as original PDF objects wherever possible to maintain the same print and screen quality as your source documents.
Can I reverse a merge operation?
Merged files are exported as new documents. Keep your original files to revert changes or re-run the merge with different settings.
How many files can I merge at once?
Large-scale merges are possible, but for optimal performance with hundreds of files, consider using batch processing or a desktop solution.
