Upload Signature/Photo

Select your camera snapshot or scanned image from your device.

2

Choose Mode & Color

Pick 'Portrait & Object' or 'Signature' mode and pick a solid color or transparent backdrop.

3

Download PNG

Click 'Remove Background Now' and save your crisp PNG immediately.

Frequently Asked Questions (FAQ)

1. How do I remove shadows and paper yellowing from my signature?
Select 'Signature & Document Mode'. Our intelligent luminance threshold filter strips away paper shadows, notebook lines, and light variations, isolating pure dark blue or black ink into a clean transparent PNG.
2. Can I use this transparent signature on PDF documents and MS Word?
Yes. The output is downloaded in true alpha-channel PNG format, meaning you can place your signature over PDF contract lines or Word certificates seamlessly.
3. Are my signatures or personal photos uploaded to remote servers?
No. All pixel rendering and background subtraction happen 100% locally inside your device's browser memory via HTML5 Canvas. Your sensitive signatures never leave your phone or computer.
