Clean Signature Online: Remove Grey Background (Black & White)

Taking a photo of a signature with a phone often results in a grey or shadowy background. Uploading this to IBPS or UPSC can lead to rejection.

The Fix: Use the DocSet Signature Cleaner.

How it Works

Our tool uses a "Threshold Algorithm".

If pixel is grey -> Turn Pure White.

If pixel is dark ink -> Turn Pure Black.

Instructions:

Sign on white paper with a Black Gel Pen.

Upload to DocSet.

Toggle "Enhance (B&W)".

Download the crisp image.

Note: For Banking Exams (IBPS/SBI), Black Ink is mandatory. Blue ink may be rejected.
