This tool runs entirely in your browser. Nothing is uploaded, nothing is stored, and you can even turn off your internet connection before you start.

How it works

  1. Add two files: the PDF with form fields in it, and a CSV whose first row is the column headings.
  2. Name the columns after the fields. Case, spaces and underscores are ignored, so “Full name” fills “full_name”.
  3. Choose one merged PDF for printing, or a file per row for sending out.
  4. Download and check the first copy before you print two hundred.

Frequently asked questions

Where do the form fields come from?
From the PDF you add. Make them in Acrobat, LibreOffice Draw or any form editor: a text field named “name”, another named “date”, and so on. A PDF with no fields has nothing to fill, and the tool says so.
Why are the fields no longer editable afterwards?
Because each copy is flattened — the field becomes ordinary printed text. Two copies of the same form in one file would otherwise share their field names and show the same values on every page.
Which field types work?
Text fields, checkboxes, dropdowns and radio groups. A checkbox is ticked for anything except an empty cell, 0, no, false or off.
How many rows can it do?
Up to five hundred in one run. Past that a browser struggles to hold the result; split the list and run it twice.
Is my list uploaded?
No. The PDF and the spreadsheet are read in your browser and the copies are made there — which matters, because a mail merge list is usually a list of real people.
