You get a mix of PDFs—invoices, contracts, receipts—and you need them sorted by type so the right workflow handles each one. Doing that by hand doesn't scale.

The fix: Define your classification rules on dev.pdf4me.com (using regex or JavaScript expressions), then run the same classification inside n8n: download a PDF (e.g. from Dropbox) → PDF4me Classify Document → use the returned className to route or organize. Classification lives in your PDF4me account; n8n just sends the file and gets back the class.

This guide has two parts. Part 1 is on dev.pdf4me.com: where to go and how to set up your first class (e.g. pdf4me_invoice with a regex like invoice(.*)). Part 2 is on n8n: a three-node workflow (Trigger → Download a file → Classify document) and how to read the result. All steps and screenshots are fact-checked from the PDF4me and n8n UIs.

If you're using n8n for automation, adding HTML headers and footers to your PDFs is straightforward—four nodes, no code. This guide shows you how to set up an n8n workflow that downloads a PDF from Dropbox, adds your custom header or footer using PDF4me, and uploads the branded file back. You paste HTML directly into the Add HTML header footer to PDF node—no separate header file needed.

You get PDFs—invoices, payment slips—each with a Swiss QR code that holds who’s paying, how much, and which reference. You want those files renamed by that data so you can find and sort them in a snap. Doing it by hand doesn’t scale.

The fix: an n8n workflow that downloads the PDF, uses Read Swiss QR Code (PDF4me) to pull out that structured payment data, merges it with the file, and uploads it with a new name—by creditor, amount, reference, or whatever you need. Same file, better filename, zero manual renaming.

This guide walks you through the full flow: download the PDF, read its Swiss QR code, then merge and upload with a filename built from the data you care about—creditor name and city, amount and reference, or debtor details.

You receive PDFs—shipping labels, inventory sheets, invoices—each with a barcode or QR code holding the tracking number, serial ID, or product code you need. You want them renamed by that value so you can find them later. Doing that by hand? It eats hours.

Sound familiar? You're not alone. Manual renaming doesn't scale.

The fix: an n8n workflow that downloads the PDF, uses Read Barcode From PDF (PDF4me) to extract the value from the barcode or QR code, merges that value with the file, and uploads it with the new name. Same content, new filename—no manual renaming.

This guide walks you through the full flow: download the PDF, read its barcode value, then merge and upload the file with the barcode as the new filename.

You receive PDFs—invoices, contracts, purchase orders, reports—and need them renamed by invoice number, customer name, order ID, or contract reference so you can find them later. Doing that by hand? It eats hours.

Sound familiar? You're not alone. Manual renaming doesn't scale.

The fix: an n8n workflow that downloads the file, uses PDF4me Parse Document to extract the value from inside the PDF, merges that value with the file, and uploads it with the new name—automatically. Same content, new filename. No code required.

This guide walks you through three steps: create a parse template in the PDF4me dashboard, wire up Download → Parse document in n8n, then add Merge and Upload so the file is saved with the extracted value as its name.
