What PlainMerge is
PlainMerge creates multiple personalized PDFs from a PDF template and spreadsheet rows. Users can drag spreadsheet headers into positions on the template or match them to native PDF form fields. It supports native PDF forms, custom fonts, multi-page documents, and QR code rendering. Spreadsheet inputs can be .xlsx, .xls, or .ods files. The app can produce personalized PDFs, send emails with PDF attachments, or do both. Its desktop version works offline and is available for macOS, Windows, and Linux. The maker also links to Mergram, an online service for merging PDFs in a browser without installation. PlainMerge is described as open source, and its GitHub repository displays an AGPL-3.0 license. The paid plan costs $59, paid once as a one-time fee for macOS, Windows, and Linux. There is no free plan, though a trial version is available for personal use; no trial duration is stated. Support is offered by email and GitHub Discussions. The product page says purchases are not refundable, while its privacy policy says data may be retained indefinitely, including in backups.
