Why file order matters
When combining several PDFs, the order controls how the final document reads. If pages are out of sequence, the merged result can become confusing or unusable.
Before you merge
- Name files clearly if possible
- Decide the final reading order first
- Remove duplicates if needed
- Check if each file opens correctly on its own
Best use cases for merging
Merging is especially useful for combining reports, contracts, scanned pages, invoices, and supporting documents into one upload-ready PDF.
