Turn your signature into a transparent PNG

Sign a sheet of white paper, take a photo with your phone and upload it. The tool removes the paper, keeps only the ink and trims the margins: you get a transparent PNG you can place on top of any document.

How it works

  1. Photograph your signature

    Sign with a dark pen on white paper and take the photo in good light, with no shadows.

  2. Adjust the sensitivity

    Move the slider until the paper disappears and the whole stroke is visible. You can make the ink black or blue.

  3. Download the PNG

    Download the signature with a transparent background and paste it into Word, Google Docs or your PDF editor.

How to get a clean signature

Use a pen or marker with a thick, dark line; pencils and worn-out pens leave a faint stroke that blends into the paper. Take the photo from directly above, with the paper flat and even lighting: shadows from your hand or phone are the most common cause of gray smudges. If smudges remain, raise the sensitivity a little; if the stroke looks broken, lower it.

How to use the signature in your documents

In Word or Google Docs, insert the image and choose the “In Front of Text” wrapping option so you can move it freely over the signature line. In a PDF, use your reader's add image or signature feature. Keep the PNG somewhere safe: it's your signature, and anyone who has the file could paste it into a document.

Frequently asked questions

How do I make my signature with a transparent background?

Sign a sheet of white paper, take a photo of it and upload it to this tool. The paper is removed automatically and you download a PNG that contains only the stroke, with a transparent background.

How do I paste my signature into a Word document?

In Word, go to Insert, Pictures and choose the PNG. Then, in the layout options, select “In Front of Text” to place it over the signature line.

Is it safe to upload my signature here?

Yes, because it isn't uploaded. The photo of your signature is processed inside your browser and is never sent to or stored on a server.

Can I change the ink color?

Yes. You can keep the pen's original color or convert the stroke to pure black or to blue, the most common color for handwritten signatures.

Is a PNG signature legally valid?

An image of your signature is a basic electronic signature: it's accepted for many everyday purposes, but it isn't equivalent to a certificate-based digital signature. For important contracts, check which type of signature is required.

Does it work for stamps and logos too?

Yes. It works with any dark stroke on a light background: stamps, line drawings or scanned logos.
