Remove Signature Background — Free Online Tool
Have a photo of your handwritten signature but the white background ruins your document? This tool turns it into a transparent PNG you can paste onto any document — contracts, PDFs, letters, and forms.
How It Works
- Upload a photo or screenshot of your signature (dark ink on white paper works best)
- Adjust the threshold slider until the background disappears
- Choose to keep the original ink color, or force it to black, red, or blue
- Download as a transparent PNG
Tips for Best Results
- Write with a dark pen on plain white paper
- Take the photo in good, even lighting — avoid shadows
- Get as close as possible so the signature fills the frame
- If edges look rough, lower the threshold slightly
