SIGNATURE & HANDWRITING
Online Signature Pad
Write or sign with a mouse, touchpad, finger, touchscreen or stylus, then save the result as a PNG.
Phone or touch display: draw with your finger. Desktop: click and drag with a mouse or touchpad.
The saved PNG is automatically cropped around your handwriting. Your drawing stays in your browser.
How to create a signature image
- Write or sign inside the drawing area.
- Adjust pen width, ink color or background if needed.
- Use Undo or Clear to make corrections.
- Select Save PNG to download the image.
Use your finger on mobile
The pad is touch enabled. On a phone, tablet or touch monitor, draw directly with your finger. While your finger is inside the drawing area, the browser does not scroll the page.
Use a mouse or touchpad on desktop
On a computer, click and drag with a mouse. A laptop touchpad works the same way because the browser receives it as pointer input.
Transparent PNG for documents
Transparent PNG is useful when you want to place handwriting or a signature over a PDF, Word document, slide or image. Utilumi crops the exported image around the handwriting automatically.
Private browser-based drawing
Your strokes stay in the browser session and the PNG is generated locally. For regulated or legally sensitive workflows, follow your organization's approved signing process.
