Tips for Flawless PDF Merging

1. Rename Files Chronologically Before Uploading

If you are uploading more than 10 documents, naming them in sequence (e.g., Doc-1, Doc-2, etc.) helps you quickly verify the structure at a glance without having to open and read through each preview box.

2. Check for Portrait and Landscape Mixes

Merging vertical (Portrait) pages with horizontal (Landscape) pages works perfectly in our tool, but if your merged file is intended for physical printing, try to keep the orientations consistent for a cleaner look.
