Split PDF by barcode using Zapier: separate a scanned batch into one file per document with PDF4me
· 21 min read
Split by Barcode is a PDF4me action for Zapier that cuts one scanned batch into separate PDFs wherever a barcode appears. A six step Zap watches Dropbox, filters for PDFs, splits on a QR code, loops over the resulting documents, and saves each one with its own name and log line.
Scan twenty invoices in one pass and you get one PDF with eighty pages. Splitting it by page number only works if every invoice is the same length, and they never are. A barcode separator sheet solves that: the split happens wherever the barcode is, whatever the page count. These screenshots come from a Zap that ran on 03 November 2026.
