Signature Background Remover
Photo or scan of your signature in, clean transparent PNG out — ready for PDFs, Word and e-sign documents.
How to remove the background from a signature
- Sign on plain white paper with a dark pen.
- Take a photo in good light (or scan it) and upload it.
- Adjust Sensitivity until the strokes are clean and the paper is gone.
- Click Download PNG — the background is transparent.
Tips for a clean signature
- Use a black or blue gel pen or marker — thin ballpoint lines can look faint.
- Shoot from straight above in daylight, and avoid your phone's shadow over the paper.
- Fill most of the photo with the signature for the sharpest result.

Frequently asked questions
How do I make my signature transparent?
Sign on plain white paper, take a photo or scan it, and upload it here. The paper is removed automatically and you download your signature as a transparent PNG.
The paper has shadows — will that work?
Yes. The tool measures the paper's brightness across the whole photo, so shadows and uneven light from a phone camera are removed too. If faint grey spots remain, lower Sensitivity.
Some of my strokes are missing or too thin
Raise Sensitivity to keep lighter pen strokes. Using a dark pen (black or blue) and good light gives the cleanest result.
Can I change the ink colour?
Yes. Keep the original pen colour or switch to black, blue or navy — handy for official documents that ask for blue ink.
Is my signature uploaded anywhere?
No. Everything happens in your browser. Your signature never leaves your device, which matters for something this sensitive.
How do I add the signature to a PDF or Word document?
In Word, use Insert → Pictures and choose the PNG. In most PDF editors (Adobe Acrobat, Preview on Mac and others), add it as an image or as your saved signature.
