FAQ

Use dark ink on plain white paper, in bright even light, holding the camera directly above. Sharp, evenly lit photos give the cleanest result.

It decides which pixels count as ink. Too high keeps paper noise; too low eats thin strokes. Aim for solid strokes with a clean background.

About this tool: Signature Maker

A reusable transparent signature image

The Signature Maker converts a photo of your handwritten signature into a clean PNG with a transparent background — the asset you paste into PDFs, contracts and letters instead of printing, signing and scanning every time. Write on plain white paper, photograph or scan it, drop it in, and the tool isolates the ink from the paper.

The output is a high-contrast, transparent PNG that layers perfectly over document text: no white box, no grey paper texture, just your signature. Keep it once and reuse it in Word, Google Docs, PDF editors and e-mail — signing digital documents becomes a two-second paste.

Like every Piclizer tool, processing is local: your signature — legally sensitive material — is analysed in your browser and never uploaded. Store the result safely, exactly as you would protect a physical signature card.

Like every Piclizer tool, this one runs entirely in your browser — your files stay on your device.
