How to Create and Download a Digital Signature (Step-by-Step)

Draw or type your legal electronic signature and export a crisp, transparent PNG ready to sign PDF contracts and documents:

1Choose Mode: Draw or Type

Select 'Draw' to sign naturally with your mouse, finger, or stylus pen on the canvas, or 'Type' to generate elegant cursive script signatures.

2Customize Ink Color & Stroke Width

Pick classic fountain pen Black, legal Blue, or custom shades, and adjust pen thickness from fine point to bold fountain pen stroke.

3Refine & Smooth Signature

Use the clear button to retry if needed. The built-in Bezier curve engine smooths pen jitter for a natural handwriting appearance.

4Download Transparent PNG

Click 'Download Signature' to save an ultra-sharp PNG with a transparent background, ready to paste into Adobe Acrobat, Word, or Google Docs.

Free Online Digital Signature Maker & Electronic Signer

Signing PDF documents, employee contracts, invoices, and tenancy agreements digitally shouldn't require printing sheets of paper, writing with ballpoint pens, and scanning murky gray files back to your computer.

Our Digital Signature Maker offers a responsive, pressure-sensitive electronic signature pad optimized for smartphones, tablets, iPads with Apple Pencil, stylus pens, trackpads, and desktop mice. It exports crisp transparent background PNG images with zero white borders that you can easily insert into Microsoft Word, Google Docs, Adobe Acrobat, and email clients.

Need to convert your documents after signing? Merge signed pages with our JPG to PDF Converter or format text notes using our Text to PDF Converter.
