A transparent signature PNG can sit over a document without a white box. Signature maker creates one by drawing or typing; it does not import a photograph.
Draw on the pad or choose Type and enter your name. Set the available colour and stroke or text controls, then save the trimmed transparent PNG. Check its ink at the size it will appear on the document.
If you already photographed a signature, use Erase background separately and manually remove the paper before saving a transparent PNG. Signature maker itself has no photo-import or automatic background-removal feature.
Keep signature images private and use them only with permission. A reusable PNG is an image of a mark, not proof of identity, a certificate or an audit trail. Ask the recipient which signing method is acceptable.
The pad is large, so draw at a comfortable size with your finger or a stylus and let the tool trim it to the ink. A pen thickness of three to five looks natural, and thicker looks like a marker. Black is the most neutral choice and blue looks like a pen.
If you would rather not draw, the Type tab writes your name in a script style. The look of those styles depends on the fonts on your device, so check it on the screen you will use. The file is saved as signature.png, ready to upload into Sign PDF.
JPG cannot store transparency. Keep the signature as PNG for placement on a PDF.
No. Draw or type here, or manually erase a photo's background in Erase background.
Three to five looks most natural on a document. Thicker lines look more like a marker than a pen.
