Merge PDF
Combine multiple PDF files into one, in the order you choose.
Introduction
Merge PDF combines several existing PDFs into one ordered document. It is well suited to a complete attachment pack when a recipient needs invoices, letters or supporting files in one place.
Use cases
- Create one case attachment from multiple supporting PDFs.
- Combine monthly records into a review bundle.
- Put invoices, slips and screenshots into a logical reading order.
Steps
- Add the source PDFs in the order the reader should see them.
- Reorder or remove a file if the sequence is wrong.
- Download the merged PDF and check the first, middle and final page.
Example
Practical example
Example: combine invoice pages, courier slips and support screenshots into one PDF before sending a reimbursement or account-support email.
Limitations
- A merged document preserves problems present in its original files.
- Password-protected or damaged PDFs may need separate handling.
- Check that the final file stays within the recipient’s attachment-size limit.
