How to make a transparent signature
Quick answer: sign on white paper, take a photo, upload it above and click Remove background. The paper becomes transparent, the edges are trimmed and you can switch the ink to black or blue. Download the PNG and place it on any PDF, Word or Google Docs file. The image never leaves your device.
- Sign on clean white paper with a dark pen.
- Take a photo in even light, with no shadows.
- Upload and click Remove background. A preview with a checkerboard shows the transparent areas.
- Adjust if needed. If grey paper remains, move the Background removal slider to the left and click again; if thin strokes disappear, move it to the right.
- Download the PNG.
