Add Signature to PDF: practical guide
Place a signature onto a PDF
This tool is useful when you need to add a signature image or signature mark to an existing PDF for routine document workflows.
Common signing workflows
Use it for acknowledgements, approvals, forms, internal documents, letters, and other files where a visible signature needs to be placed on the page.
Visible signature vs digital certificate signature
Adding a visible signature image is not the same as applying a cryptographic digital signature backed by a certificate. Requirements vary by organization and jurisdiction.

You may also need Add Date to PDF, Add Text to PDF, or Flatten PDF depending on the workflow.
Check acceptance requirements
For legal, regulated, or official submissions, confirm whether a simple visible signature is accepted or whether a certified electronic-signature platform is required.

What format works best?
A transparent PNG usually looks best.
Should I use this on documents I do not own?
Only add a signature when you are authorized to sign or mark the document.
