Add GiroCode to PDF Invoice

The code. The same EPC QR builder as the EPC QR / GiroCode Generator (EPC069-12 version 3.0): you enter name, IBAN and optionally BIC, amount, purpose, a reference or free-text remittance, and a note. Errors are shown immediately, and the code only appears when the data is valid.

Placing it. A preview of the chosen page is shown with the code on top. Drag it with the mouse or finger, move it with the arrow keys (Shift for 5 mm steps), and set its size in millimetres. The size is that of the QR itself without its white quiet zone; a white border of four modules is added around it so it scans. Find free space scans the rendered page from the lower right and puts the code in the first blank area large enough for it; if the code covers existing content you get a warning with the share of the area that is not blank.

Minimum size. The EPC guideline gives no print size. The Swiss QR-bill guideline requires at least 0.4 mm per module, and the tool uses that verified figure as a cautious reference: below it you are warned and told how wide the code should be at least (modules multiplied by 0.4 mm). It is a safe lower bound, not an EPC requirement.

The result. The page content is kept and the code is appended to it. Pages with a rotation are handled: the code is drawn upright as the page is displayed. The file is saved again by the browser library, which has consequences: digital signatures no longer verify (the tool warns if it sees one), and PDF/A or tagged-PDF claims in the file are not updated. Check the result by scanning it from the screen or a print before you send it.

PDF files up to 50 MB, any page size, one code per run (run it again for another page). Encrypted PDFs are not opened. EPC QR version 001 and 002, euro only.

1. Drag in the invoice PDF.
2. Enter the payment details and check for messages.
3. Choose the page, set the size, and drag the code to a clear spot, or press Find free space.
4. Press Add QR code and download, then scan the result with a banking app.

• Adding a payment code to an invoice exported from software that has no QR option
• Putting the code on a reminder or a donation letter
• Fixing an invoice whose code was forgotten, without regenerating the whole document
• Producing a print-ready invoice with a code of a chosen size
• Testing several placements before you change an invoice template

The tool does not guarantee that every bank will scan every result. Scanning depends on the code size, print quality, contrast and the app. It adds a code to the page content as it is; it does not know the layout of your invoice and finds blank space only by looking at the pixels of the rendered page.

The edited file is a re-saved PDF: signatures break, and conformance claims such as PDF/A are not re-established. The code is not accessible to screen readers; keep the payment details in text on the invoice as well.
