Split PDFs by Barcode in Make: Iterator + PDF4me Split by Barcode (Step-by-Step)

When you scan a stack of documents into one PDF, the easiest way to split it is by barcode separator pages. PDF4me’s Split by Barcode module does exactly that—and Make’s Iterator turns the split results into individual files you can upload to Dropbox.

This guide is fact‑checked from the provided Make screenshots, including the exact module names, fields, and sample values.

What You Need

• Make — Create a Make account and open a new scenario.
• PDF4me API key — Get your API key and connect it to PDF4me.
• Dropbox — This guide uses Dropbox, but any storage connector with download + upload works the same.

4. Dropbox – Upload a File — Uploads each split PDF file.
