Sign a sheet of paper, take a photo, and get a transparent PNG signature that sits cleanly on any document.
A photographed signature carries the paper with it — grey tint, shadows from your phone, and texture. Dropped onto a PDF it looks like a pasted rectangle.
Removing the background leaves just the ink. Precision mode is designed for thin structures like hair, which makes it a good fit for fine pen strokes.
Sign on white paper: Use a dark pen with a bold line. Photograph it flat in even light, avoiding your phone's shadow.
Remove the background: Precision mode keeps the thin, tapered ends of strokes.
Download as PNG: Transparent PNG drops onto Word, Google Docs, PDF editors and email signatures.
Thin strokes kept: Fine pen lines are preserved instead of breaking up.
No grey box: Paper tint and shadows are removed completely.
Vector option: Run the PNG through the Vectorizer for an infinitely scalable SVG signature.

Which pen works best? A black felt-tip or gel pen gives the cleanest, highest-contrast result.
