Why you may need this tool

Many submissions and sharing workflows require a single PDF file. When documents are split across multiple files—scans, appendices, receipts, or separate pages—sending them individually increases the risk of missing pages or confusing order. Merging PDFs helps you produce one coherent document that is easier to review, upload, archive, and share.

How to use

Add PDFs, confirm the order, merge, then quickly verify the first and last pages before you share the result.

Examples

Submitting multiple attachments as one file

Portals often accept only one file for a submission. Merging allows you to combine the required pages into a single PDF and reduce upload mistakes.

Creating a readable sequence for review

Reviewers expect a logical order and consistent flow. Reordering and merging helps you avoid confusion caused by scattered documents and inconsistent naming.

Benefits & differentiators

A single merged file reduces overhead for both the sender and the reviewer. It also makes naming and storage easier: one file per submission or case is simpler to track. When you can control ordering, you can build a clear document flow (cover → body → appendix), which improves readability and reduces back - and - forth requests for clarification.

Who this is for

Recommended if you: - need to upload one PDF instead of multiple files - combine scans, appendices, or receipts into a package - want a clear cover/body/appendix flow - reduce page loss and ordering mistakes
