Why Merge PDF Files?
Combining multiple PDF documents into a single file is one of the most common document management tasks. Whether you're consolidating reports, combining scanned pages, or organizing project files, merging PDFs saves time and keeps your documents organized.
Common Use Cases
- Business Reports: Combine monthly reports, financial statements, or presentations into quarterly or annual compilations.
- Legal Documents: Merge contracts, addendums, and supporting documents into complete case files.
- Academic Work: Combine research papers, references, and appendices into a single submission.
- Scanned Documents: Merge multiple scanned pages into one cohesive document.
Tips for Best Results
Before merging, ensure all your PDFs are in the correct orientation. Use our Rotate PDF tool if needed. For large merges, consider the final file size - our Compress PDF tool can help reduce it after merging.
