About Remove Signature Background
A background remover built for signatures. It measures the paper around every stroke, so phone shadows, cream or gray paper and uneven light divide out, and it measures the paper's grain, so texture comes out empty while faint pencil stays solid. Strokes keep smooth edges with no white halo, specks and smudges are dropped, and the desk around a photographed sheet is ignored. Compare before and after with the slider, erase anything left over, keep your pen's color or pick one, then download a transparent PNG or a JPG on white, or send it straight to Sign PDF.

Frequently asked questions
How do I make my signature transparent?+
Sign on white paper, take a photo in good light and add it here. The paper becomes transparent automatically and only the ink is kept, so the PNG sits on any document without a white box around it.
Does it work with shadows, lined paper or a desk around the sheet?+
Yes. Uneven light and phone shadows are evened out, the desk around the sheet is dropped, and Remove printed lines erases the line you signed on or the lines of ruled paper while keeping the strokes that cross them.
Can I keep the color of my pen?+
Original color keeps your pen's real color without the paper's tint. You can also make every stroke black, blue or any color you choose.
Something is left over or a faint stroke is missing. What can I do?+
Move the Clean-up slider toward Cleaner to drop leftover marks, or toward Keep faint ink for pencil and light pens. For a single spot, use the Eraser and paint over it.
Is my signature uploaded anywhere?+
No. The photo is processed in your browser and never leaves your device.
