Processing for this tool

Temporary server processing in GermanySignature modes

This tool uses temporary SentryPDF server processing on Fly.io in Frankfurt am Main, Germany. Temporary files are configured for 30 minutes and the cleanup sweep runs every 60 seconds.

If the file is highly confidential, prefer a browser-local tool or browser-local mode when one can do the job well.

Sign PDF supports visible signature appearance and certificate-based digital signing. Visible mode is not cryptographic; digital mode signs on the temporary server in Germany.
