Draw or type a signature

Draw mode

A white canvas with a black stroke, sized to the pad. It listens for pointer events, so a mouse, a trackpad, a stylus and a finger all work without a separate mobile path. Each completed stroke updates the stored image, and a bin button clears it if the first attempt was unconvincing. What is captured is the whole canvas, which is why the stamper aligns the ink to the left of its box: the mark stays where the person drew it.

Type mode

You type your name and it appears in a script face at 44 pixels. Behind that, after a short pause, the name is drawn onto an off-screen canvas at twice the pixel density and exported as a PNG. So what is submitted is an image, not text with a font attached. That matters, because a font that failed to load or a reader that substituted one could otherwise change what a signed document looks like.

Switching between them keeps both

The pad holds a drawn version and a typed version separately, so flipping between the modes does not destroy your first attempt. Whichever mode is active is the one submitted. Starting to draw clears the typed name and typing clears the drawing on the canvas, so there is never any doubt about which mark is live.

How it is stored

The image is uploaded to storage as a PNG or JPEG under its recipient's own key, and the row keeps the storage key plus a sha256 of the bytes rather than the picture itself. That hash is printed on the certificate of completion as the signature image hash, so the mark on the page can be tied to a specific set of bytes rather than just looking about right.

The record says which you used

Draw or typed is stored on the recipient row and carried into the signed event in the audit trail alongside the image hash, the hash of the document at that moment, and the consent version accepted. Neither mode is treated as lesser. The record simply says what happened, which is more useful in a dispute than a claim that all signatures are equally handwritten.

How it works, in three steps

1. Step 1

   Open the pad

   Tap any signature or initials box on the document, or the button in the header, and the pad opens over the page.

2. Step 2

   Pick a mode

   The pen button draws on the canvas. The letter button takes your typed name and renders it in a script face.

3. Step 3

   Use it everywhere

   Press Use signature and the mark fills every signature, initials and block spot at once, then the header steps you through them.

Limits worth knowing

• One signature image per signer per envelope. It cannot differ between fields on the same document.
• The image must be a PNG or JPEG, capped at two million characters of encoded data, which the pad never approaches.
• There is no upload-your-own-image option and no stored signature carried between envelopes.
• Type mode uses one script face. There is no choice of style.
