How to use this tool
Frame and drop the paper
Zoom in if the signature is small, drag the corner brackets to frame the ink, then move the threshold. Sample the paper if the sheet is uneven.
Download a PNG
The left preview is the transparent ink. The right preview shows it on a page. JPEG fills white.

Built for predictable results
Built for ink, not portraits
A brightness threshold keeps strokes. This is not the portrait cutout used in Image Background Remover.
Two views of the same file
Checkerboard shows what you download. The page view shows how the signature sits on a document.
Private
The scan never leaves your device. Pixlery does not receive the file.

Frequently asked questions
Is the download a transparent PNG?
Yes by default. PNG and WebP keep paper pixels clear. JPEG cannot store transparency, so empty areas fill white.
How do I turn a scanned signature into a PNG?
Upload the scan, frame the ink, adjust the threshold until paper disappears, then download. That is the scan-signature and signature-to-PNG path on this page.
What if the pen is light or the paper is shadowed?
Sample a clean paper spot and raise the threshold slowly. Pale pencil and heavy shadows can still leave haze or drop thin strokes. High-contrast black ink on white paper works best.
Is this a legal electronic signature?
No. This makes an image of handwriting on paper. It does not create a qualified electronic signature or have legal effect by itself.
How is this different from Image Background Remover?
Use Image Background Remover for people or products. This page only lifts handwriting off paper and will not try a portrait model.
Can I crop first or put the PNG in a PDF?
Yes. Tighten the frame here, or refine the scan in Image Cropper. For a round mark, use Round profile picture. To place pages in a document, open Images to PDF.
