About Sign PDF
Place a drawn or uploaded signature image on a PDF page — offline image stamp, not a cryptographic e-sign.
Wet-ink scans are slow. This places a PNG/JPEG signature image on a chosen page at a fixed position and size — a visual stamp, the same category as “paste my signature PNG,” not DocuSign certificate theater.
Page index is 0-based in the control. The image is not a free-drag canvas in the current UI; it lands at a consistent offset. Edit PDF text is for wording; Redact is for removing content.
If you need legally binding certificate signatures, use a proper e-sign product. This keeps the bytes on your device.

Common questions
Is this a legally binding electronic signature?
It is an image overlay. Whether that meets your jurisdiction’s rules is a legal question — we do not claim certificate-based e-sign.
Can I drag the signature anywhere?
Not in this UI. Position and size are fixed defaults for a quick stamp.
Is the PDF uploaded?
No.

Why this one doesn't upload your file
