SIGNATURE IMAGE GUIDE
This tool creates a signature image
It saves strokes drawn with a mouse, finger, or stylus as a transparent PNG. That is useful for placing an image on a document or PDF, but it is not an identity-verification service and does not create a legally binding electronic signature, certificate, or audit trail.
How to place it naturally in a document
- Sign on a screen with enough empty space, using a dark color.
- Choose a stroke width that fits the text in the document.
- Download the transparent PNG, insert it, and check its size and position.
If a line is interrupted on mobile
Tap the signing area once, then draw slowly with a finger or stylus. After rotating the screen or resizing the browser, check the signature once more before downloading.
