If you have a scanned copy of your handwritten signature, you can insert it directly into any PDF — perfect for contracts, letters, and forms that require a wet-ink look without printing and scanning.

Sign on white paper, scan or photograph it, then open it in any free tool (e.g. remove.bg or Photoshop) to remove the white background and export as PNG.
Yes. The Sign PDF tool at pdfeditor.onl/sign-pdf lets you draw your signature directly in the browser with a mouse or finger — no scanning needed.
