How to Remove the Background From a Signature (Free Transparent PNG)

Scanned or photographed your signature? Here's how to remove the white background and get a clean transparent PNG to drop into PDFs and documents — free, in your browser.

To sign a PDF or a contract digitally, you usually need your signature as a transparent PNG — so it sits on the document like real ink, not inside a white box. Here's how to take a photo or scan of your handwritten signature and remove the background for free, right in your browser.

Step by step

• Step 1 — Sign your name in black pen on white paper and take a clear, well-lit photo (or scan it).
• Step 2 — Open Skrubly's AI Background Remover and drop the image in.
• Step 3 — It removes the white paper background, leaving just your signature on transparency.
• Step 4 — Download the transparent PNG and drop it onto your PDF or document.

Why do it in your browser (privacy matters here)

Your signature is sensitive — it's the kind of thing you really don't want sitting on a stranger's server. Because Skrubly runs the AI in your browser, your signature image is never uploaded anywhere. That's a big deal for something as personal as your signature, and most online background removers can't say the same.

Tips for a clean signature

• Use a dark pen on plain white paper for the best contrast.
• Good, even lighting with no shadows gives the cleanest edges.
• If the result looks faint, sign with a thicker pen and retake the photo.
