How do I make my signature transparent?
Take a photo of your signature on white paper and drop it here. The tool measures the paper brightness, makes it transparent and keeps the ink — even in phone photos with grey or uneven paper.
Why does my signature look faint or patchy?
Increase Sensitivity and Edge smoothness, or choose black ink. A darker pen, better light and a straight-on photo also help.
Can I use it to sign a PDF?
Yes. Download the PNG, then add it with our PDF Signature tool or any PDF editor.
Is it safe to process my signature here?
Yes — the image is processed in your browser and never uploaded. Still, only share signature images with people and services you trust.
Are my images uploaded?
No. Everything happens in your browser, so your images never leave your device.
