By Jetformat
Supply a PEM certificate and RSA private key. This creates a cryptographic signature; a drawn signature image or ink annotation is a different operation.
Steps
- Start with a local PDF. Replace the sample paths and identifiers with your own.
- Run the command below. Save to a new output path so the source remains available for comparison.
- Check the result as described below before using it in another job.
jetformat pdf sign book.pdf --cert cert.pem --key key.pem -o signed.pdfOptions for this task
| Option | Meaning |
|---|---|
--cert |
PEM certificate path |
--key |
PEM RSA private key path |
--name |
Signature display name (default “Jetformat”) |
--output |

Check the result
Use a PDF signature validator to review integrity, certificate trust, and signer identity. Editing a signed output can affect validity.
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 sign --help to compare options with your installed version.
