Frequently Asked Questions

Why does my signature need a transparent background? ▼

A transparent background lets you stamp your signature onto documents, contracts, or emails without a white box covering the text underneath it.

What does the sensitivity slider do? ▼

It controls how aggressively light-colored pixels are treated as background. Increase it for scans with shadows or off-white paper, decrease it if parts of your signature are being removed.
