This adds a picture of a signature. It does not create a cryptographic digital signature or verify identity.

The original remains unchanged. Open the downloaded PDF and inspect every edited page.
Useful edits, clear limits.
All PDF processing happens locally in your browser tab. Files and drawn signatures are discarded when you close the tab. The site does not receive them.
These tools add visible content or fill standard PDF fields. They do not remove hidden content, securely redact a PDF, certify a signature, or read scanned text. Password-protected PDFs are not supported.
