Adding a date to every page of a PDF is useful for version control, legal documents, and reports that need to show when they were prepared or approved. Here is how to do it automatically for free.
Go to pdfeditor.onl/header-footer and upload your PDF.
In the header or footer zone where you want the date, type {{date}}. The tool will automatically replace this with today's date when generating the PDF.
Tip: Place the date in the Left zone of the footer for a clean document layout: date on the left, page number on the right.
You can add context around the date: "Prepared: {{date}}" or "Version dated {{date}}". Combine it with page numbers: "{{date}} — Page {{page}}".
Click Download. Every page now carries the date. This is especially useful for sending reports where the recipient should know when the document was finalized.
The {{date}} token inserts today's date automatically. For a custom date, simply type the date as plain text in the zone — for example "March 2026".
The token uses the ISO format (YYYY-MM-DD) by default. For a different format, type the date manually as plain text.
