How to combine PDFs for a job or school packet

A working order for cover letters, forms, and certificates: fix page order, merge the files, then compress if the packet is too large to send.

How to build one PDF from several application files

Put each document in the right internal order
If a scan is upside down or a form has a blank page in the middle, open Reorder PDF Pages first. Merge follows the order of whole files, not pages inside them.
Add files in the order the recipient asked for
Open Merge PDF and drop between 2 and 50 unlocked PDFs. The first file you add becomes the first pages of the packet.
Merge, then open the result
Download the combined PDF and count the pages. Merging does not unlock a password-protected file; the tool will refuse it.
Compress only if you need a smaller attachment
If email or a portal rejects the packet, run Compress PDF on the merged file. Keep the uncompressed merge until you have checked the compressed copy.

A packet is an order problem, then a file problem

Cover letters, application forms, and certificates often arrive as separate downloads. Recipients usually want one PDF in a stated sequence. Reorder PDF Pages is for the inside of one file. Merge PDF is for joining those files in the list order you choose.

Add the files again if you dropped them in the wrong sequence. The merge tool does not include a thumbnail sorter for the whole packet. Closing the tab before you download discards the merged copy; we do not keep a draft.

After you have one PDF

Open it and check every section the recipient named. If the packet is too large to attach, compress the merged file rather than sending a ZIP of originals unless they asked for that. If they need images instead of a multi-page PDF, convert the pages you need with PDF to JPG.
