## What this tool does
Photo of a handwritten signature → transparent PNG with hardened ink, ready to place on contracts.

## Typical user problems
- You signed a white page, photographed it, and now need just the ink on a transparent layer to drop into contract PDFs and Word templates. Manual erasing in an editor is fiddly and always leaves grey paper residue.
- The contract arrived as a PDF; printing, signing and rescanning is a round trip you do not have time for. Extract your signature once and place it on the signature line.
