PDFs
Place it on a PDF with the PDF signer. The signature goes on top of the page, so the original text and fonts are unchanged.
Make a Digital Signature PNG
Create a transparent PNG of your signature to place on documents, PDFs, and images. This is a picture of your signature, which is what most people mean by the phrase.
Private by design. Your signature is processed on your device and never uploaded.
How to make a digital signature PNG
- 01
Pick how to create it
Upload a photo of a signature on paper, draw one on screen, or type your name in a handwriting font. The tool above has a tab for each.
- 02
Make the background transparent
Uploaded photos are cleaned automatically. Drawn and typed signatures are already transparent.
- 03
Download the PNG
The PNG keeps its transparency, so it sits on the page without a white box.
- 04
Use it where you need it
Sign a PDF or image with it here, or insert it as a picture in a document editor or email signature.
Where a signature PNG is useful
Images and scans
Sign a photo of a form or a screenshot and keep the file in its original format.
Word processors and slides
Most editors can insert a picture. Because the PNG is transparent, it shows the page behind it. Send the final file as a PDF if you do not want it edited.
Email signatures
Many mail apps let you add an image to your signature block. Use a small PNG so it loads quickly.
Why PNG and not JPG
Transparency
JPG cannot be transparent, so a JPG signature always carries a white or coloured rectangle. PNG does not.
Sharp edges
JPG compression smudges thin lines. A PNG keeps pen strokes crisp, even when you scale them down.
Frequently asked questions
What is a digital signature PNG?
It is an image of your signature saved as a PNG with a transparent background. You place it on a document to show where and how you sign.
Is a PNG signature legally binding?
It depends on the document, where you are, and who receives it. A signature image is a simple electronic signature. It does not prove identity by itself. This is not legal advice: for contracts that matter, ask the other party or a qualified professional what is required.
Is this the same as a certificate-based digital signature?
No. A certificate-based digital signature is cryptographic and tied to an identity. PureSign creates and places the image of your signature. It does not issue certificates or verify who you are.
Can I make one without creating an account?
Yes. The tool works as a guest. An account is only needed to save signatures to a vault.
Is the file uploaded?
No. Photos, drawings, and the finished PNG stay in your browser unless you choose to save the signature to your vault.
