Tips for Merging PDFs Smoothly

  1. Rename your files with numbers (01_cover, 02_report, 03_appendix) before uploading — it makes reordering faster and less error-prone.
  2. Check each individual PDF for the correct page orientation before merging; a sideways page is easier to fix beforehand than after.
  3. If your merged file feels too large afterward, run it through a PDF compression tool to bring the size down without affecting the merge.
