Add a document timestamp through a TSA

Use jetformat pdf timestamp to add a document timestamp through a TSA.

By Jetformat

A timestamp authority is a network dependency, so this step differs from a purely local edit. Choose an endpoint approved for your workflow.

Steps

  1. Start with a local PDF. Replace the sample paths and identifiers with your own.
  2. Run the command below. Save to a new output path so the source remains available for comparison.
  3. Check the result as described below before using it in another job.
jetformat pdf timestamp book.pdf --tsa https://freetsa.org/tsr -o ts.pdf

Options for this task

Option Meaning
--name Timestamp display name (default “Jetformat”)
--output Output PDF path (required)
--tsa Timestamp server URL (required)

Check the result

Validate the timestamp token and authority trust in a compatible PDF validator before relying on it.

Notes and limits

This operation uses page-based credits. Review the billing guide before processing a large document.

The examples keep the original file. Add --force only when you intend to overwrite an existing output. Run jetformat pdf timestamp --help to compare options with your installed version.

See the pdf command reference for the surrounding workflow.
