Sign a PDF With Your Signature Image

A form wants a signature on page four, and printing nine pages to sign one line is not a serious option. Add your signature as a picture, choose the page and corner, and the file comes back with your ink drawn into the page itself — not an annotation a viewer can hide. Nothing leaves your device.

How to sign a PDF with your signature image

  1. Choose both files together: the PDF and a picture of your signature.
  2. Pick the pages that need signing — leave the box empty for every page.
  3. Set the width and nudge the position until it sits like you wrote it.
  4. Press Sign the PDF, save the result, and check the page before you send it.

How the signature is drawn into the file

Your PNG becomes part of the page: an image placed at print resolution with its transparency carried through, so the ink sits over the line the form drew and whatever is underneath stays visible. It is not an annotation a reader can delete or fail to render — every tool that opens the PDF sees your signature exactly where you put it, at the size you chose.

Placement is measured from the corner you pick, in millimetres, on the page as it looks on screen. A scan that carries its own sideways flag is handled in the space you see, so bottom-right means bottom-right of the page in front of you, not of the raw scan underneath.

What happens to the rest of your document

Only the pages you named are touched. Everything else travels through byte for byte, and the page count, order and text never change. Two things a rewrite cannot carry are said out loud when they apply: bookmarks are lost, and a filled form keeps its answers as printed ink rather than editable fields.

A photo of a signature on white paper has no transparency to keep, so it is laid onto white and the note beside the result says so. Crop the picture tight around the ink before you start and the stamp sits cleanly on whatever is underneath.

Questions

Is a typed name in a script font the same thing?
No, and portals increasingly say so. A picture of your own signature is the thing they are asking for; this page draws that picture into the file without turning it into anything else.
Can anyone tell the PDF was signed with a tool?
There is no stamp, watermark or added page naming us, and the file carries no editor metadata from this step. What a careful reader CAN see is that the document was rewritten rather than appended to — same as any PDF editor produces.
Why do you need the signature as an image?
Because drawing it is the whole job: the engine places a picture object on the page. Photograph your signature on white paper, crop it tight, and save it as PNG — that is the one input this page cannot make for you.
Do either of my files leave my device?
No. The reading, the placement and the writing all happen inside this tab. That is the reason to use this instead of a site that asks you to upload a signed contract to somebody else’s server first.
