Overview
Merging PDF files combines separate documents into one ordered packet. It is useful when a submission, client handoff, or archive needs a single file instead of many attachments. A merge workflow should preserve page order and make it easy to review the final document before sharing.
After merging, consider adding page numbers, compressing the final packet for email, or splitting out sections for different recipients. A single merged file is easier to track, but it should still be named clearly.
When to use it
Merge PDFs for job applications, insurance claims, legal exhibits, accounting records, school submissions, onboarding packets, and reports assembled from multiple contributors. It is especially useful when a scanner creates one file per page or when a portal only accepts one upload.
Step by step
- Open the Merge PDF tool.
- Add each PDF in the order you want it to appear.
- Reorder files if the cover page, forms, or appendices are not in the right sequence.
- Run the merge process.
- Download the combined PDF and scan through the page order before sending.
Privacy
Merge PDF is a local-first organization task. Files can be combined in the browser where possible, which is appropriate for packets containing IDs, invoices, signed pages, contracts, and internal records.
