- To submit one file instead of many separate uploads
- To attach supporting annexures to a main document

Best practice before merging PDFs
Before you merge PDFs, rename the source files clearly and arrange them in the final order you want. If you are working with scans, check that each file is upright and readable first. It is much easier to fix the order before combining than after the final merged PDF is downloaded.
Tip: if some pages are sideways or upside down, use a rotate PDF tool before merging so the final packet is clean.
