What “sign PDF” means here

You already have a signature scan. This page draws it onto the PDF in this browser. HR and many visa checklists accept that. It is not DocuSign, Adobe Sign, or a PAdES certificate. Flatten the file afterwards if the portal rejects live form fields. Last checked: September 2026.

On this device

pdf-lib stamps the image. Close the tab and both files are gone. No account. No watermark. Crop a 10–20 KB ink JPEG on the signature resizer first if the form also wants a separate signature upload.
