💡 Tips & Best Practices
- Arrange your files in the desired order before merging — most tools process files sequentially
- Check page orientation and size consistency across source files for the best results
- Review the merged document's table of contents and bookmarks after combining
- For large merges, consider doing them in batches to avoid memory issues
- Name your output file descriptively so you can easily identify its contents later
