Place a signature on an image with control

This workflow layers your signature over a local image and lets you position it visually. Use it for documents that explicitly allow an inserted signature image; it does not replace a digital certificate, e-sign service or witnessed signature when those are required.

Keep the mark readable without covering printed text, dates or seals. Review the final image at full resolution, because a placement that looks clear in the small editor can overlap content after download.

  • Confirm image signatures are allowed.
  • Leave surrounding text readable.
  • Save the unsigned original separately.

Signing runs entirely on your device. Your photos and signature data are never uploaded.

Frequently asked questions

How do I add a signature to a photo or image?

Upload your image, draw or place a transparent signature on top, position and size it, then download the signed image.

Can I overlay a transparent signature PNG?

Yes. Upload a transparent signature and drop it onto the photo, or draw a new one directly.

Will the signature have a white box around it?

No, if you use a transparent signature. Make one with the transparent signature tool first for a clean overlay.

Is it free and private?

Yes — free, no watermark, and the image is processed in your browser, never uploaded.
