How to Merge on Mac
- Open Merge PDF in Safari or Chrome
- Drop all your PDF files at once (or add them one by one)
- Drag to reorder — arrange files in the sequence you want
- Click Merge — download the combined PDF
Why not Preview? Preview works for 2-file merges. But for combining 5+ files into a specific order, the browser tool is significantly faster — you see all files at once, drag to reorder, and merge in one click.
How to Merge on Windows
- Open Merge PDF in Chrome or Edge
- Drop PDF files from File Explorer
- Reorder if needed and click Merge
Windows has zero built-in PDF merge capability. The browser tool fills this gap without installing anything.
Common Merge Workflows
- Contract + attachments: Merge the main contract with exhibits, schedules, and signature pages into one document
- Report assembly: Combine cover page, executive summary, data sections, and appendix from separate files
- Application package: Merge resume, cover letter, transcripts, and references into a single submission file
- Meeting packet: Combine agenda, previous minutes, financial reports, and proposals for board distribution
- Scan collection: Merge multiple scanned pages into one continuous document
After Merging — Common Next Steps
- Compress PDF — merged files can be large. Compress to reduce size for emailing or storage
- Add Page Numbers — add continuous numbering across the merged document
- Add Watermark — stamp branding or confidentiality notices
- Bates Numbering — add legal document numbering for court filings
