When 12 MB helps
Use it for larger support packets
Use 12 MB when the destination gives that room for a larger set of supporting pages. Do not assume every large upload allows 12 MB; check the real instructions in your workflow.
12 MB targetLarger support PDFs
Prepare a PDF for a 12 MB upload limit
12 MB is useful when the upload workflow allows a larger support or evidence packet and the PDF needs readable scans, images, or several pages. Use the target shown by the destination.
Keep it focused
Merge only what belongs together
Combine files only when the same upload step expects those documents in one PDF. Delete unrelated pages and keep the order clear before preparing.
Readability
Use the room to preserve detail
A larger target can protect fine text, stamps, photos, and scans from unnecessary degradation. Smaller is not always better when the upload allows more room.

Boundary: 12 MB is a target inside the preparation workflow, not a promise that a destination will accept the file. The destination portal has the final say.
